74VCXH245 Low Voltage Bidirectional Transceiver with Bushold

June 1999

Revised April 2005

74VCXH245

Low Voltage Bidirectional Transceiver with Bushold

General Description

The VCXH245 contains eight non-inverting bidirectional

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

ented applications. The T/R input determines the direction

of data flow. The OE input disables both the A and B Ports

by placing them in a high impedance state. The VCXH245

data inputs include active bushold circuitry, eliminating the

need for external pull-up resistors to hold unused or float-

ing data inputs at a valid logic level.

The 74VCXH245 is designed for low voltage (1.2V to 3.6V)

applications.

The 74VCXH245 is fabricated with an advanced CMOS

technology to achieve high-speed operation while main-

taining low CMOS power dissipation.

Features

1.2V to 3.6V V
