TinyLogic
ULP-A D-Type Flip-Flop
with Preset and Clear
General Description
The NC7SV74 is a single D-type CMOS Flip-Flop with pre-
set 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 V
CC
) and applications that require more drive
and speed than the TinyLogic ULP series, but still require
low power consumption.
The NC7SV74 is uniquely designed for optimized power
and speed, and is fabricated with an advanced CMOS
technology to achieve high-speed operation while main-
taining 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.

Absolute Maximum Ratings
(Note 1)
Recommended Operating
Conditions
(Note 3)
Note 1: Absolute Maximum Ratings: are those values beyond which the
safety of the device cannot be guaranteed. The device should not be oper-
ated at these limits. The parametric values defined in the Electrical Charac-
teristics tables are not guaranteed at the absolute maximum ratings. The
"Recommended Operating Conditions" table will define the conditions for
actual device operation.
Note 2: I
O
Absolute Maximum Rating must be observed.
Note 3: Unused inputs must be held HIGH or LOW. They may not float.
