DESCRIPTION
The 74ALVC574 is a high-performance, low-power,
low-voltage, Si-gate CMOS device and superior to most
advanced CMOS compatible TTL families.
The 74ALVC574 is an octal D-type flip-flop featuring
separate D-type inputs for each flip-flop and 3-state
outputs for bus oriented applications. A clock (CP) input
and an output enable (OE) input are common to all
flip-flops.
The eight 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 eight flip-flops is
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 ‘574’ is functionally identical to the ‘374’, but the ‘374’
has a different pin arrangement.
