DESCRIPTION
The 74VHCT574A is an advanced high-speed
CMOS OCTAL D-TYPE FLIP FLOP with 3
STATE OUTPUT NON INVERTING fabricated
with sub-micron silicon gate and double-layer
metalwiring C
2
MOStechnology.
This 8 bit D-Type flip-flop is 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 logic states that were setup
at the D inputs.
While the OE input is low, the 8 outputswill be in
a normal logic state (high or low logic level) and,
while high level, the outputs will be in a high
impedancestate.
The output control does not affect the internal
operation of flip flop; that is, the old data can be
retained or the new data can be entered even
whilethe outputsare off.
Power down protection is provided on all inputs
and outputs and 0 to 7V can be accepted on
inputs with no regard to the supply voltage. This
device can be used to interface5V to 3V.
All
inputs
and
outputs are
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.

PIN CONNECTION AND IEC LOGIC SYMBOLS
