54ACTQ574

Quiet Series Octal D Flip-Flop with TRI-STATE^®Outputs

General Description

Features

n I_CCand I_OZreduced by 50%

The ACTQ574 is

a high-speed, low-power octal D-type

flip-flop with a buffered Common Clock (CP) and a buffered

common Output Enable (OE). The information presented to

the D inputs is stored in the flip-flops on the LOW-to-HIGH

clock (CP) transition.

n Guaranteed simultaneous switching noise level and

dynamic threshold performance

n Inputs and outputs on opposite sides of the package

allowing easy interface with microprocessors

n Functionally identical to the ACTQ374

n TRI-STATE outputs drive bus lines or buffer memory

address registers

n Outputs source/sink 24 mA

n Faster prop delays than the standard ACT574

n 4 kV minimum ESD immunity

ACTQ574 utilizes Quiet Series technology to guarantee

quiet output switching and improve dynamic threshold per-

™

formance. FACT Quiet Series features GTO output con-

trol and undershoot corrector in addition to a split ground bus

for superior performance.

The ACTQ574 is functionally identical to the ’ACTQ374 but

with different pin-out.
