16-Bit Dual-supply Bus Transceiver with 3-state Outputs
REJ03D0157-0200Z Rev.2.00 Jan.07.2004
Description
The HD74ALVC165245A 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 1.4 V to 3.6 V, and the B port is designed to track VCCB, which operates at 1.2 V to 2.7 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.

The absolute maximum ratings are values which must not individually be exceeded, and furthermore, no two of which may be realized at the same time. 1. The input and output voltage ratings may be exceeded even if the input and output clamp-current ratings are observed. 2. The maximum package power dissipation was calculated using a junction temperature of 150C.

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.
