DESCRIPTION

The 74V CX16374 i s a low voltage CMOS 16 BIT
D-TYPE FLIP-FLOP with 3 STATE OUTPUTS
NON INVERTING fabricated with sub-micron
silicon gate and five-layer metal wiring C

MOS
technology. It is ideal for low power and very high
speed 1.8 to 3.6V applications; it can be interfac ed
to 3.6V signal environment for both inputs and
outputs.
These 16 bit D-TYPE flip-flops are controlled by
two clock inputs (nCK) and two output enable
inputs (nOE

).
Onthepositivetransitionofthe(nCK),thenQ
outputs wi ll be s et to the logic state that were
setup at the nD inputs.
While the (nOE

) input is low, the 8 outputs (nQ)
will be in a normal state (HIGH or LOW logic lev el)
and while high level the outputs will be in a high
impedance state.
Any output control does not aff ec t 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.
All inputs and outputs are equipped with
protection circuits against static discharge, givi ng
them 2KV ESD immunity and transient excess
voltage.
