74AUP2G79集成電路（IC）的觸發(fā)器規(guī)格書PDF中文資料

1. General description

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.
