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)
V
CC
applications with I/O compatibility up to 3.6V.
The 74VCX245 is fabricated with an advanced CMOS
technology to achieve high-speed operation while main-
taining low CMOS power dissipation.
