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

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

: series resistor helps reduce out-

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.

Features

s 5V tolerant inputs and outputs

s Power down high impedance inputs and outputs

s Supports live insertion/withdrawal (Note 1)

s

s Implements patented noise/EMI reduction circuitry

s Latch-up performance exceeds 500 mA

s Equivalent 26

: series resistor on all outputs

s ESD performance:

Human body model

! 2000V

Machine model

! 200V

Note 1: To ensure the high-impedance state during power up or down, OE

resistor is determined by the current-sourcing capability of the driver.
