DESCRIPTION
The 74LCX16374 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 C²MOS
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 16 bit D-TYPE flip-flops are controlled by
two clock inputs (nCK) and two output enable in-
puts(nOE). On the positive transition of the (nCK),
the nQ outputs will be set 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 level) and while high level the
outputs will be in a high impedance state.
Any output control does not affect the internal op-
eration of flip flops; that is, the old data can be re-
tained 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 protec-
tion circuits against static discharge, giving them
2KV ESD immunity and transient excess voltage.
