74LCX2244

Low Voltage Buffer/Line Driver with 5V Tolerant Inputs

and Outputs with 26â¦ Series Resistors in the Outputs

General Description

The LCX2244 contains eight non-inverting buffers with

3-STATE outputs. The device may be employed as a mem-

ory address driver, clock driver and bus-oriented transmit-

ter/receiver. The LCX2244 is designed for low voltage

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

ing to a 5V signal environment. The 26â¦ series resistors

help reduce output overshoot and undershoot.

The LCX2244 is fabricated with an advanced CMOS tech-

nology to achieve high speed operation while maintaining

CMOS low power dissipation.

Features

s 5V tolerant inputs and outputs

s 2.3V to 3.6V VCC specifications provided

s 7.5 ns tPD max (VCC = 3.3V) 10 ÂµA ICC max

s Power down high impedance inputs and outputs

s 26â¦-series resistors in the outputs

s Supports live insertion/withdrawal (Note 1)

s Â±12 mA output drive (VCC = 3.0V)

s Implements patented noise/EMI reduction circuitry

s Latch-up performance exceeds 500 mA

s ESD performance:

Human body model > 2000V

Machine model > 200V

s Leadless DQFN package

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

should be tied to VCC through a pull-up resistor: the minimum value or the

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