GENERAL DESCRIPTION
The ADG792A/ADG792G are monolithic CMOS devices, each comprising three 4:1 multiplexer/demultiplexers that are controllable through a standard I2C serial interface. The CMOS process provides ultralow power dissipation yet delivers high switching speed and low on resistance. The on resistance profile is very flat over the full analog input range, and wide bandwidth ensures excellent linearity and low distortion. These features, combined with a wide input signal range, make the ADG792A/ADG792G the ideal switching solution for a wide range of TV applications, including RGB and YPbPr video switches. When turned on, the switches conduct equally well in both directions. In the off condition, signal levels, up to the supplies, are blocked. The ADG792A/ADG792G switches exhibit breakbefore-make switching action. The ADG792G also has two general-purpose logic output pins controllable through the I2C interface to control other non-I2C-compatible devices, such as video filters. The integrated I2C interface provides a large degree of flexibility in the system design. To build larger switching arrays, the user can set the three I2C address pins allowing as many as eight devices to connect to the same bus. The ADG792A/ADG792G operate from a single 3 V or 5 V supply voltage and is available in a compact 4 mm x 4 mm body, 24-lead, Pb-free, LFCSP package.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Only one absolute maximum rating can be applied at any one time.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

ADG792A/ADG792G THEORY OF OPERATION
The ADG792A/ADG792G are monolithic CMOS devices, each comprising three 4:1 multiplexer/demultiplexers controllable via a standard I2C serial interface. The CMOS process provides ultralow power dissipation yet it delivers high switching speed and low on resistance. The on resistance profile is very flat over the full analog input range and the wide bandwidth ensures excellent linearity and low distortion. These features, combined with a wide input signal range, make the ADG792A/ADG792G the ideal switching solution for a wide range of TV applications. The switches conduct equally well in both directions when on. In the off condition, signal levels up to the supplies are blocked. The integrated serial I2C interface controls the operation of the multiplexers and general-purpose logic pins. The ADG792A/ADG792G have many attractive features, such as the ability to individually control each multiplexer, the option of reading back the status of any switch, and two general-purpose logic output pins controllable through the I2C interface (available with the ADG792G only). The following sections describe these features in more detail. 4. The transitions on the SDA line must occur during the low period of the clock signal, SCL, and remain stable during the high period of SCL, because a low-to-high transition when the clock signal is high can be interpreted as a stop event which ends the communication between the master and the addressed slave device. After transferring all data bytes, the master establishes a stop condition, defined as a low to high transition on the SDA line while SCL is high. In write mode, the master pulls the SDA line high during the tenth clock pulse to establish a stop condition. In read mode, the master issues a no acknowledge for the ninth clock pulse (the SDA line remains high). The master then brings the SDA line low before the tenth clock pulse, and then high during the tenth clock pulse to establish a stop condition.
I2C ADDRESS
The ADG792A/ADG792G has a seven-bit I2C address. The four most significant bits are internally hardwired and the last three bits (A0, A1, and A2) are user-adjustable. This allows the user to connect up to eight ADG792A/ADG792Gs to the same bus. The I2C bit map shows the configuration of the seven-bit address.
I2C SERIAL INTERFACE
The ADG792A/ADG792G are controlled via an I2C-compatible serial bus interface (refer to the I2C-Bus Specification available from Philips Semiconductor) that allows the part to operate as a slave device (no clock is generated by either the ADG792A or the ADG792G). The communication protocol between the I2C master and the device operates as follows: 1. The master initiates data transfer by establishing a start condition defined as a high to low transition on the SDA line while SCL is high. This indicates that an address/data stream follows. All slave devices connected to the bus respond to the start condition and shift in the next eight bits, consisting of a seven bit address (MSB first) plus an R/W bit. This bit determines the direction of the data flow during the communication between the master and the addressed slave device. The slave device whose address corresponds to the transmitted address responds by pulling the SDA line low during the ninth clock pulse (this is termed the acknowledge bit). At this stage, all other devices on the bus remain idle while the selected device waits for data to be written to, or read from, its serial register. If the R/W bit is set high, the master reads from the slave device. However, if the R/W bit is set low, the master writes to the slave device. 3. Data transmits over the serial bus in sequences of nine clock pulses (eight data bits followed by an acknowledge bit).
Seven-Bit I2C Address Bit Configuration
MSB 1 0 1 0 A2 A1 LSB A0
WRITE OPERATION
When writing to the ADG792A/ADG792G, the user must begin with an address byte and R/W bit, after which time the switch acknowledges that it is prepared to receive data by pulling SDA low. Data is loaded into the device as a 16-bit word under the control of a serial clock input, SCL. Figure 31 illustrates the entire write sequence for the ADG792A/ADG792G. The first data byte (AX7 to AX0) controls the status of the switches and the LDSW and RESETB bits from the second byte control the operation mode of the device. Table 6 shows a list of all commands supported by the ADG792A/ADG792G with the corresponding byte that needs to be loaded during a write operation. To achieve the desired configuration, one or more commands can be loaded into the device. Any combination of the commands listed in Table 6 can be used with the following restrictions: * * Only one switch from a given multiplexer can be on at any given time. When a sequence of successive commands affect the same element (that is, the switch or GPO pin), only the last command is executed.

ADG792A/ADG792G
LDSW BIT
The LDSW bit allows the user to control the way the device executes the commands loaded during the write operations. The ADG792A/ADG792G execute all the commands loaded between two successive write operations that have set the LDSW bit high. Setting the LDSW high for every write cycle ensures that the device executes the command immediately after the LDSW bit is loaded into the device. This setting is used when the desired configuration can be achieved by sending a single command, or when the switches and/or GPO pin are not required to be updated at the same time. When the desired configuration requires multiple commands with a simultaneous update, the LDSW bit should be set low while loading the commands, except for the last one when the LDSW bit should be set high. Once the last command with LDSW = high is loaded, the device simultaneously executes all commands received since the last update. operation of the multiplexers and GPO pins, this bit should be set high. When RESETB = low, or after power-up, the switches from all multiplexers are turned off (open) and the GPO pins are set to low.
READ OPERATION
When reading data back from the ADG792A/ADG792G, the user must begin with an address byte and R/W bit. The switch then acknowledges that it is prepared to transmit data by pulling SDA low. Following this acknowledgement, the ADG792A/ ADG792G transmit two bytes on the next clock edges. These bytes contain the status of the switches, and each byte is followed by an acknowledge bit. A logic high bit represents a switch in the on (close) state, and a low represents a switch in the off (open) state. For the GPO pin (ADG792G only), the bit represents the logic value of the pin. Figure 32 illustrates the entire read sequence. The bit maps accompanying Figure 32 show the relationship between the elements of the ADG792A and ADG792G (that is, the switches and GPO pins) and the bits that represent their status after a completed read operation.
POWER ON/SOFTWARE RESET
The ADG792A/ADG792G have a software reset function implemented by the RESETB bit from the second data byte loaded into the device during a write operation. For normal
