74LCX244

Low Voltage Buffer/Line Driver with 5V Tolerant

Inputs and Outputs

Features

■ 5V tolerant inputs and outputs

■ 2.3V to 3.6V VCC specifications provided

■ 6.5ns tPD max. (VCC = 3.3V), 10µA ICC max.

■ Power down high impedance inputs and outputs

■ Supports live insertion/withdrawal(1)

■ ±24mA output drive (VCC = 3.0V)

■ Implements proprietary noise/EMI reduction circuitry

■ Latch-up performance exceeds 500mA

■ ESD performance:

– Human body model > 2000V

– Machine model > 200V

■ 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.

General Description

The LCX244 contains eight non-inverting buffers with

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

memory address driver, clock driver and bus-oriented

transmitter/receiver. The LCX244 is designed for low

voltage (2.5V or 3.3V) VCC applications with capability of

interfacing to a 5V signal environment.

The LCX244 is fabricated with an advanced CMOS tech-

nology to achieve high speed operation while maintain-

ing CMOS low power dissipation.
