U74LVC1G79
SINGLE
POSITIVE-EDGE-TRIGGERED
D-TYPE FLIP-FLOP
DESCRIPTION
The U74LVC1G79 is a single positive-edge-triggered D-type
flip-flop.
When data at the data input (D) meets the set-up time
requirements, the data is transferred to the outputs (Q) on the
positive-going edge of the clock pulse. Following the hold-time
interval, data at the D input can be changed without affecting the
level at the outputs.
This device has power-down protective circuit, preventing device
destruction when it is powered down.
FEATURES
* Operate from 1.65V to 5.5V
* Inputs accept voltages to 5.5V
* Ioff supports partial-power-down mode
* Low power dissipation: ICC=10μA (Max.)
* ±24mA output drive(VCC=3.3V)
