DESCRIPTION
The 74LCX574 is a low voltage CMOS OCTAL

technology. It is ideal for low power and high
speed 3.3V applications; it can be interfaced to 5V
signal environment for both inputs and outputs.
These 8 bit D-Type flip-flops are controlled by a
clock input (CK) and an output enable input (OE).
On the positive transition of the clock, the Q

outputs will be set to the logic state that were
setup at the D inputs.
While the (OE) input is low, the 8 outputs will be in
a normal logic state (high or low logic level) and
while high level the outputs will be in a high
impedance state.
The Output control does not affect the internal
operation of flip flops; that is, the old data can be
retained or the new data can be entered even
while the outputs are off.
It has same speed performance at 3.3V than 5V
AC/ACT family, combined with a lower power
consumption.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
