DESCRIPTION

The 74LVX374 is a low voltage CMOS OCTAL
D-TYPE FLIP- FLO P with 3 STAT E OUT PUT NON
INVERTING fabricated with sub-micron silicon
gate and double-layer metal wiring C

MOS
technology. It is ideal for low power, battery
operated and low noise 3.3V applications.
This 8 bit D-Type flip-flop is controlled by a clock
input (CK) and an out put enable input (OE

). O n
the positive transition of th e clock, the Q outputs
will be set to the logic state that were set up at t he

D inputs. While the (OE

) input is low, the 8 outputs
will be in a norm al logic state (high or low logic
level) and while high le vel the outpu ts 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.
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. It
combines high speed performance with the true
CMOS low power consumption.
All inputs and outputs are equipped with
protection circuits against stat ic discharge, giving
them 2KV ESD immunity and transient excess
voltage.
