74LCX2244

Low Voltage Buffer/Line Driver with 5V Tolerant Inputs

and Outputs with 26Ω Series Resistors in the Outputs

General Description

Features

■ 5V tolerant inputs and outputs

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) V_CCapplications with capability of interfac-

■ 2.3V to 3.6V V_CCspecifications provided

■ 7.5 ns t_PDmax (V_CC= 3.3V) 10 µA I_CCmax

■ Power down high impedance inputs and outputs

■ 26Ω-series resistors in the outputs

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

help reduce output overshoot and undershoot.

■ Supports live insertion/withdrawal (Note 1)

■ ±12 mA output drive (V_CC= 3.0V)

The LCX2244 is fabricated with an advanced CMOS tech-

nology to achieve high speed operation while maintaining

CMOS low power dissipation.

■ Implements patented noise/EMI reduction circuitry

■ Latch-up performance exceeds 500 mA

■ 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 V_CCthrough a pull-up resistor: the minimum value or the

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