16-Bit Dual-supply Bus Transceiver with 3-state Outputs
REJ03D0158-0201 Rev.2.01 Apr. 12, 2005
Description
The HD74ALVC166245A has 16 bus transceivers with three state outputs in a 48-pin package. When (DIR) is high, data flows from the A inputs to the B outputs, and when (DIR) is low, data flows from the B inputs to the A outputs. A and B bus are separated by making enable input (OE) high level. This 16-bit non-inverting bus transceiver uses two separate power-supply rails. And this product has two terminals (VCCA, VCCB), VCCA is connected with A bus side, VCCB is connected with control input and B bus. VCCA and VCCB are isolated. The A port is designed to track VCCA, which accepts voltages from 1.2 V to 2.7 V, and the B port is designed to track VCCB, which operates at 1.4 V to 3.6 V. Therefore, Bidirectional broad voltage conversion is possible. Low voltage and high-speed operation is suitable at the battery drive product (note type personal computer) and low power consumption extends the life of a battery for long time operation.
Features
* This product function as level shift transceiver that change VCCA input level to VCCB output level, VCCB Input level to VCCA output level by providing different supply voltage to VCCA and VCCB. * VCCA = 1.2 V to 2.7 V, VCCB = 1.4 V to 3.6 V (VCCA < VCCB) * All control input VI (max) = 3.6 V (@VCCB = 0 V to 3.6 V) * All A bus side input outputs VI/O (max) = 3.6 V (@VCCA = 0 V or output off state) * All B bus side input outputs VI/O (max) = 3.6 V (@VCCB = 0 V or output off state) * High output current A bus side: 2 mA (@VCCA = 1.2 V) B bus side: 4 mA (@VCCB = 1.50.1 V) 4 mA (@VCCA = 1.50.1 V) 6 mA (@VCCB = 1.80.15 V) 6 mA (@VCCA = 1.80.15 V) 18 mA (@VCCB = 2.50.2 V) 24 mA (@VCCB = 3.30.3 V) 18mA (@VCCA = 2.50.2 V) * Ordering Information

Power-up considerations
Level-translation devices offer an opportunity for successful mixed-voltage signal design. A proper power-up sequence always should be followed to avoid excessive supply current, bus contention, oscillations, or other anomalies caused by improperly biased device pins. Take these precautions to guard against such power-up problems. 1. Connect ground before any supply voltage is applied. 2. Next, power up the control side of the device. (Power up of VCCB is first. Next power up is VCCA.) 3. Tie OE to VCCB with a pullup resistor so that it ramps with VCCB. 4. Depending on the direction of the data path, DIR can be high or low. If DIR high is needed (A data to B bus), ramp it with VCCB. Otherwise, DIR low is needed (B data to A bus), ramp it with GND.
