74VCX32245

Low Voltage 32-Bit Bidirectional Transceiver

with 3.6V Tolerant Inputs and Outputs (Preliminary)

General Description

The VCX32245 contains thirty-two non-inverting bidirec-

tional buffers with 3-STATE outputs and is intended for bus

oriented applications. The device is byte controlled. Each

byte has separate 3-STATE control inputs which can be

shorted together for full 32-bit operation. The T/R inputs

determine the direction of data flow through the device.

The OE inputs disable both the A and B ports by placing

them in a high impedance state.

The 74VCX32245 is designed for low voltage (1.65V to

3.6V) V

The 74VCX32245 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing low CMOS power dissipation.

Features

Note 1: To ensure the high-impedance state during power up or power

down, OE should be tied to V

value of the resistor is determined by the current-sourcing capability of the

driver.
