DESCRIPTION

The 74V1G79 is an advanced high-speed CMOS
SINGLE POSITIVE EDGE TRIGGERED D-TYPE
FLIP-FLOP fabricated with sub-micron silicon
gate and double-layer metal wiring C

MOS

technology. it is design ed to operate from 2V to

5.5V, making this device ideal for portable
applications.
This D-Type flip-flop is controlled by a clock input
(CK). On the positive transition of the clock, the Q
output will be set to the logic state t hat was setup
at th e D input.

Following the hold time interval, data at the D input
can be changed without affecting the level at the
output. Power down protection is provided on
inputs and 0 to 7V can be accepted on inputs with
no regard to t he supply voltage. This device can
be used to interface 5V to 3V systems.
It’s available in the commercial and extended
temperature range. All inputs and output are
equipped with protection circuits against static
discharge, giving them ESD immunity and
transient excess voltage.
