74LV574
Octal D-type flip-flop;
positive edge-trigger (3-State)
The 74LV574 is a low-voltage Si-gate CMOS device and is pin and
function compatible with 74HC/HCT574.
The 74LV574 is an octal D-type flip–flop featuring separate D-type
inputs for each flip-flop and non-inverting 3-state outputs for oriented
applications. A clock (CP) 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
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.
Output voltage levels are compatible with input levels of CMOS,
NMOS and TTL IC
