74LCXH16245

Low Voltage 16-Bit Bidirectional Transceiver

with Bushold

General Description

The LCXH16245 contains sixteen non-inverting bidirec-

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

oriented applications. The device is designed for low volt-

age (2.5V or 3.3V) VCC applications with capability of inter-

facing to a 5V signal environment. The device is byte

controlled. Each byte has separate control inputs which

could be shorted together for full 16-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 LCXH16245 data inputs include active bushold cir-

cuitry, eliminating the need for external pull-up resistors to

hold unused or floating data inputs at a valid logic level.

The LCXH16245 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing CMOS low power dissipation.
