74LCXR2245

Low Voltage Bidirectional Transceiver with

5V Tolerant Inputs and Outputs and

26: Series Resistors on Both A and B Ports

General Description

The LCXR2245 contains eight non-inverting bidirectional

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

ented applications. The device is designed for low voltage

(2.5V and 3.3V) V

ing to a 5V signal environment. The T/R input determines

the direction of data flow through the device. The OE input

disables both the A and B ports by placing them in a high

impedance state. The 26

put overshoot and undershoot.

The LCXR2245 is fabricated with an advanced CMOS

technology to achieve high speed operation while maintain-

ing CMOS low power dissipation.

Ordering Code:

Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
