Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at

74VCX245 Low Voltage Bidirectional Transceiver with 3.6V Tolerant Inputs and Outputs
June 1999
Revised December 2013
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.
