74LVX574

Low Voltage Octal D-Type Flip-Flop with

3-STATE Outputs

General Description

The LVX574 is a high-speed octal D-type flip-flop which is

controlled by an edge-triggered clock input (CP) and a buff-

ered common Output Enable (OE) input. When the OE

input is HIGH, the eight outputs are in a high impedance

state. The LVX574 is functionally identical to the LVX374

but with inputs and outputs on opposite sides of the pack-

age. The inputs tolerate up to 7V allowing interface of 5V

systems to 3V systems.

Features

s Input voltage translation from 5V to 3V

s Ideal for low power/low noise 3.3V applications

s Guaranteed simultaneous switching noise level and

dynamic threshold performance

Ordering Code:

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