EIA-232-E and CCITT V.28
The MC145583 is a CMOS transceiver composed of three drivers and five receivers that fulfills the electrical specifications of EIA-232-E, EIA-562, and CCITT V.28 while operating from a single + 3.3 or + 5.0 V power supply. This transceiver is a high-performance, low-power consumption device that is equipped with a standby function. A voltage tripler and inverter converts the + 3.3 V to 8.8 V, or a voltage doubler and inverter converts the + 5.0 V to 8.8 V. This is accomplished through an on-chip 40 kHz oscillator and five inexpensive external capacitors. Drivers: * 5 V Minimum Output Swing at 3.3 or 5.0 V Power Supply * 300 Power-Off Impedance * Output Current Limiting * Three-State Outputs During Standby Mode Receivers: * 25 V Input Range * 3 to 7 k Input Impedance * 0.8 V Hysteresis for Enhanced Noise Immunity * Three-State Outputs During Standby Mode Ring Monitor Circuit: * Invert the Input Level on Rx1 to Logic Output Level on RIMON at Standby Mode

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, it is recommended that the voltage at the DI and DO pins be constrained to the range GND VDI VCC and GND VDO VCC. Also, the voltage at the Rx pin should be constrained to (VSS - 15 V) VRx1 - Rx5 (VDD + 15 V), and Tx should be constrained to VSS VTx1 - Tx3 VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., GND or VCC for DI, and GND for Rx). Min 3.0 4.5 - 40 Typ 3.3 5.0 -- Max 3.6 5.5 85 Unit V C

PIN DESCRIPTIONS
VCC Digital Power Supply (Pin 27) This digital supply pin is connected to the logic power supply. This pin should have a not less than 0.33 F capacitor GND. GND Ground (Pin 2) Ground return pin is typically connected to the signal ground pin of the EIA-232-E connector (Pin 7) as well as to the logic power supply ground. VDD Positive Power Supply (Pin 23) This is the positive output of the on-chip voltage tripler and the positive power supply input of the driver/receiver sections of the device. This pin requires an external storage capacitor to filter the 50% duty cycle voltage generated by the charge pump. VSS Negative Power Supply (Pin 5) This is the negative output of the on-chip voltage tripler/inverter and the negative power supply input of the driver/ receiver sections of the device. This pin requires an external storage capacitor to filter the 50% duty cycle voltage generated by the charge pump. RIMON Ring Monitor Circuit (Pin 4) The Ring Monitor Circuit will convert the input level on Rx1 pin at standby mode and output on the RIMON pin. STB Standby Mode (Pin 6) The device enters the standby mode while this pin is connected to the logic high level. During the standby mode,
driver and receiver output pins become high-impedance state. In this condition, supply current ICC is below 5 A (typ). C5+, C5-, C2+, C2-, C1+, C1- Voltage Tripler and Inverter (Pins 1, 3, 28, 26, 25, 24) These are the connections to the internal voltage tripler and inverter, which generate the VDD and VSS voltages. Rx1, Rx2, Rx3, Rx4, Rx5 Receive Data Inputs (Pins 7, 8, 9, 11, 13) These are the EIA-232-E receive signal inputs. A voltage between + 3 and + 25 V is decoded as a space, and causes the corresponding DO pin to swing to GND (0 V). A voltage between - 3 and - 25 V is decoded as a mark, and causes the DO pin to swing up to VCC. DO1, DO2, DO3, DO4, DO5 Data Outputs (Pins 22, 21, 20, 18, 16) These are the receiver digital output pins, which swing from VCC to GND. Output level of these pins is high impedance while in standby mode. DI1, DI2, DI3 Data Inputs (Pins 19, 17, 15) These are the high impedance digital input pins to the drivers. Input voltage levels on these pins must be between VCC and GND. Tx1, Tx2, Tx3 Transmit Data Output (Pins 10, 12, 14) These are the EIA-232-E transmit signal output pins, which swing toward VDD and VSS. A logic 1 at a DI input causes the corresponding Tx output to swing toward VSS. The actual levels and slew rate achieved will depend on the output loading (RL /CL ). The minimum output impedance is 300 when turned off.

ESD PROTECTION ESD protection on IC devices that have their pins accessible to the outside world is essential. High static voltages applied to the pins when someone touches them either directly or indirectly can cause damage to gate oxides and transistor junctions by coupling a portion of the energy from the I/O pin to the power supply buses of the IC. This coupling
will usually occur through the internal ESD protection diodes which are designed to do just that. The key to protecting the IC is to shunt as much of the energy to ground as possible before it enters the IC. Figure 1 shows a technique which will clamp the ESD voltage at approximately 15 V using the MMBZ15VDLT1. Any residual voltage which appears on the supply pins is shunted to ground through the capacitors C1 and C2.
