74AUP1G74
Low-power D-type flip-flop with set and reset; positive-edge
trigger
Rev. 04 — 3 June 2008
Product data sheet
1. General description
The 74AUP1G74 provides a low-power, low-voltage single positive-edge triggered D-type
flip-flop with individual data (D), clock (CP), set (SD) and reset (RD) inputs and
complementary Q and Q outputs. The SD and RD are asynchronous active LOW inputs
and operate independently of the clock input. 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.
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 the damaging backflow current through the device
when it is powered down.
