74VCX245

Low Voltage Bidirectional Transceiver

with 3.6V Tolerant Inputs and Outputs

General Description

The VCX245 contains eight non-inverting bidirectional buff-

ers with 3-STATE outputs and is intended for bus oriented

applications. The T/R input determines the direction of data

flow. The OE input disables both the A and B ports by plac-

ing them in a high impedance state.

The 74VCX245 is designed for low voltage (1.4V to 3.6V)

The 74VCX245 is fabricated with an advanced CMOS

technology to achieve high-speed operation while main-

taining low CMOS power dissipation.

Features

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

down, OE

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

driver.
