74LCXR2245 Rev. 1.2.0

March 2008

74LCXR2245

Low Voltage Bidirectional Transceiver with 5V Tolerant Inputs

and Outputs and 26

Ω Series Resistors on Both A and B Ports

Features

■

Ω series resistor on all outputs

– Human body model

> 2000V

– Machine model

> 200V

Note:

1. To ensure the high-impedance state during power up

resistor: the minimum value or the resistor is

determined by the current-sourcing capability of the

driver.

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 volt-

interfacing 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

Ω series resistor

helps reduce output overshoot and undershoot.

The LCXR2245 is fabricated with an advanced CMOS

technology to achieve high speed operation while main-

taining CMOS low power dissipation.

Ordering Information

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

All packages are lead free per JEDEC: J-STD-020B standard.
