POSITIVE-EDGE-TRIGGERED

D-TYPE FLIP-FLOP WITH

CLEAR AND PRESET

„ DESCRIPTION

The U74AC74 is a dual positive-edge-triggered D-type flip-flop.

The preset ( PRE ) and clear ( CLR ) input can set or reset the

output at a low level ,regardless of the level of others inputs .when

the PRE and CLR are inactive(high), data at the data D input

meeting the set-up time requirements is transferred to the outputs

on the positive-going edge of the clock pulse. Following the

hold-time interval, data D can be changed without affecting the

levels at the outputs.

„ FEATURES

* Operating voltage rauge: VCC(OPR)=2V to 6V.

* Inputs accept voltages to 6V

* Max tpd at 10ns of 5V
