Datasheet

1. General description
74AHC1G79 and 74AHCT1G79 are high-speed Si-gate CMOS devices. They provide a
single positive-edge triggered D-type flip-flop.
Information on the data input is transferred to the Q output on the LOW-to-HIGH transition
of the clock pulse. The D input must be stable one set-up time prior to the LOW-to-HIGH
clock transition for predictable operation.
The AHC device has CMOS input switching levels and supply voltage range 2 V to 5.5 V.
The AHCT device has TTL input switching levels and supply voltage range 4.5 V to 5.5 V.
