Datasheet
LOW VOLTAGE CMOS 16-BIT D-TYPE FLIP FLOP (3-STATE)
DESCRIPTION
The 74LVX16374 is a low voltage CMOS 16 BIT
D-TYPE FLIP-FLOP with 3 STATE OUTPUTS
NON INVERTING fabricated with sub-micron
silicon gate and double-layer metal wiring C
technology. It is ideal for low power, battery
operated and low noise 3.3V applications.
These 16 bit D-TYPE flip-flop is controlled by two
clock inputs (CK) and two output enable inputs
(nOE). The device can be used as two 8-bit
flip-flops or one 16-bit flip-flop.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 outputs will be in
a normal logic state (high or low logic level); while
OE is high, the outputs will be in a high impedance
state.The output control does not affect the inter-
nal 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.Power down protection is
provided on all inputs and 0 to 7V can be accepted
on inputs with no regard to the supply voltage.This
device can be used to interface 5V to 3V. All in-
puts and outputs are equipped with protection cir-
cuits against static discharge, giving them 2KV
ESD immunity and transient excess voltage.
