Low Voltage 16-Bit Bidirectional Transceiver

with 5V Tolerant Inputs/Outputs

and 26: Series Resistors in the Outputs

General Description

The LCXR162245 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) V

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.

In addition, all A and B outputs include equivalent 26

(nominal) series resistors to reduce overshoot and under-

shoot and are designed to sink/source up to 12 mA at

The LCXR162245 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing CMOS low power dissipation.
