NC7SV74
TinyLogic£ ULP-A D-Type Flip-Flop
with Preset and Clear
General Description
Features
The NC7SV74 is a single D-type CMOS Flip-Flop with preset and clear from Fairchild's Ultra Low Power-A (ULP-A)
Series of TinyLogic£ in both the space saving US8 and
MicroPak¥ packages. ULP-A is ideal for applications that
require extreme high speed, high drive and low power. This
product is designed for a wide low voltage operating range
(0.9V to 3.6V VCC) and applications that require more drive
and speed than the TinyLogic ULP series, but still require
low power consumption.
■ Space saving US8 surface mount package
The NC7SV74 is uniquely designed for optimized power
and speed, and is fabricated with an advanced CMOS
technology to achieve high-speed operation while maintaining low CMOS power dissipation.
The signal level applied to the D input is transferred to the
Q output during the positive going transition of the CLK
pulse.
■ MicroPak Pb-Free leadless package
■ 0.9V to 3.6V VCC supply operation
■ 3.6V overvoltage tolerant I/Os at VCC from 0.9V to 3.6V
■ Extremely High Speed tPD
