74AHC574; 74AHCT574
Octal D-type flip-flop; positive edge-trigger; 3-state
Rev. 02 — 24 January 2008
Product data sheet
1. General description
The 74AHC574; 74AHCT574 are high-speed Si-gate CMOS devices and are pin
compatible with Low Power Schottky TTL (LSTTL). They are specified in compliance with
JEDEC standard no. 7A.
The 74AHC574; 74AHCT574 are octal D-type flip-flops featuring separate D-type inputs
for each flip-flop and 3-state outputs for bus oriented applications. A clock (CP) and an
output enable (OE) input are common to all flip-flops.
The 8 flip-flops will store the state of their individual D-inputs that meet the set-up and hold
times requirements on the LOW-to-HIGH CP transition.
When OE is LOW the contents of the 8 flip-flops are available at the outputs. When OE is
HIGH, the outputs go to the high-impedance OFF-state. Operation of the OE input does
not affect the state of the flip-flops.
The 74AHC574; 74AHCT574 is functionally identical to the 74AHC564; 74AHCT564, but
has non-inverting outputs. The 74AHC574; 74AHCT574 is functionally identical to
the 74AHC374; 74AHCT374, but has a different pinning.
