74AUP2G79

Low-power dual D-type flip-flop; positive-edge trigger

应用领域

The 74AUP2G79 provides the dual positive-edge triggered D-type flip-flop. Information on the data input (nD) is transferred to the nQ output on the LOW-to-HIGH transition of the clock pulse (nCP). The nD input must be stable one set-up time prior to the LOW-to-HIGH clock transition for predictable operation.

Schmitt trigger action at all inputs makes the circuit tolerant to slower input rise and fall times across the entire VCC range from 0.8 V to 3.6 V.

This device ensures a very low static and dynamic power consumption across the entire VCC range from 0.8 V to 3.6 V.

This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing a damaging backflow current through the device when it is powered down.
