General description
The 74HC574; 74HCT574 is a high-speed Si-gate CMOS device and is pin compatible
with Low-power Schottky TTL. It is specified in compliance with JEDEC standard no. 7A.
The 74HC574; 74HCT574 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 74HC574; 74HCT574 is functionally identical to:
74HC564: but has non-inverting outputs
74HC374; 74HCT374: but has a different pin arrangement
