DESCRIPTION

The 74V1G79 is an advanced high-speed CMOS

SINGLE POSITIVE EDGE TRIGGERED D-TYPE

FLIP-FLOP fabricated with sub-micron silicon

technology. it is designed 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 that was setup

at the 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 the 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.
