74AUP2G79
Low-power dual D-type flip-flop; positive-edge trigger
Rev. 8 — 24 January 2013
Product data sheet
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 V
CC
range from 0.8 V to 3.6 V.
This device ensures a very low static and dynamic power consumption across the entire
V
CC
range from 0.8 V to 3.6 V.
This device is fully specified for partial power-down applications using I
OFF
. The I
OFF
circuitry disables the output, preventing a damaging backflow current through the device
when it is powered down.
2. Features and benefits
Wide supply voltage range from 0.8 V to 3.6 V
High noise immunity
Complies with JEDEC standards:
JESD8-12 (0.8 V to 1.3 V)
