CMOS IC
SINGLE
POSITIVE-EDGE-TRIGGERED
D-TYPE FLIP-FLOP
DESCRIPTION
The UTC U74AHC1G79 is a 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.
FEATURES
* Wide supply voltage range from 2.0V to 5.5V
* Symmetrical output impedance
* Balanced propagation delays
* High noise immunity

Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
