Product Description
The 74HC/HCT574 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 74HC/HCT574 are octal D-type
flip-flops featuring separate D-type
inputs for each flip-flop and
non-inverting 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 time 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 574 is functionally identical to
the 564, but has non-inverting
outputs.
The 574 is functionally identical to
the 374, but has a different pinning.
