DESCRIPTION

The 74V1T80 is an advanc ed high-speed CM OS SINGLE POSITIVE EDGE TRIGGERED D-TYPE FLIP-FLOP WITH INVERTED OUTPUT fabricated with sub-micron silicon gate and double-layer metal wiring C

2

MOS technology. it is designed to operate from 4.5V 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 inverted sta te 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 input and 0 to 7V can be accepted on input with no regard to the supply voltage. This device can be used to interface 5V to 3V. It’s available in the commercial temperature range. All inputs and output are equipped with protection circuits against stat ic discharge, giving them ESD immunity and transient excess voltage.
