74LCX821

Low Voltage 10-Bit D-Type Flip-Flop

with 5V Tolerant Inputs and Outputs

General Description

The LCX821 consists of ten D-type Flip-Flops with

3-STATE outputs for bus organized system applications.

applications with capability of interfacing to a 5V signal

environment.

The LCX821 is fabricated with an advanced CMOS tech-

nology to achieve high speed operation while maintaining

CMOS low power dissipation.

Features

■ 5V tolerant inputs and outputs

■ Power-down high impedance inputs and outputs

■ Supports live insertion/withdrawal (Note 1)

■

±24 mA output drive (V

■ Implements patented noise/EMI reduction circuitry

■ Latch-up performance exceeds 500 mA

■ 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.

Ordering Code:

Devices also available in Tape and Reel. Specify by appending the suffix “X” to the ordering code.
