NC7SZ374
TinyLogic UHS D-Type Flip-Flop with 3-STATE Output
General Description
The NC7SZ374 is a single positive edge-triggered D-type
CMOS Flip-Flop with 3-STATE output from Fairchild’s Ultra
High Speed Series of TinyLogic in the space saving
SC70 6-lead package. The device is fabricated with
advanced CMOS technology to achieve ultra high speed
with high output drive while maintaining low static power
dissipation over a very broad VCC operating range. The
device is spe cified to operate over the 1.6 5V to 5.5V VCC
range. The inputs and output are high impedance when
VCC is 0V. Inputs tolerate voltages up to 7V independent of
VCC operating voltage. This single flip-flop will store the
state of the D input that meets the setup and hold time
requirements on the LOW-to-HIGH Clock (CP) transition.
The output tolerates voltages above VCC in the 3-STATE
condition.

Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions (Note 2)
Note 1: Absolute Maximum Ratings: are those values beyond which the
safety of the dev ice can not be gu ara ntee d. The de vic e shou ld 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: Unused inputs must be held HIGH or LOW. They may not float.

Capacitance (Note 3)
Note 3: TA = +25C, f = 1MHz.
Note 4: CPD is defined as the value of th e internal equivalent c apacita nc e which is deriv ed from dy namic operat ing current con su m pt ion (ICCD) at no output
loading and operating at 50% duty cycle. (See Figure 2) CPD is related to I CCD dynam ic operating curre nt by th e expression:
ICCD = (CPD) (VCC) (fIN) + (ICCstatic).
