NC7SZ175
TinyLogic UHS D-Type Flip-Flop
with Asynchronous Clear
General Description
Features
■ Space saving SC70 6-lead package
The NC7SZ175 is a single positive edge-triggered D-type
CMOS Flip-Flop with Asynchronous Clear 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
■ Ultra High Speed; tPD 2.6 ns Typ into 50 pF at 5V VCC
■ High Output Drive; ±24 mA at 3V VCC
■ Broad VCC Operating Range; 1.65V to 5.5V
■ Matches the performance of LCX when operated at
3.3V VCC
device is specified to operate over the 1.65V to 5.5V VCC
■ Power down high impedance inputs/output
range. The inputs and output are high impedance when
■ Overvoltage tolerant inputs facilitate 5V to 3V translation
■ Patented noise/EMI reduction circuitry implemented
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. A
LOW input to Clear sets the Q output to LOW level. The
Clear input is independent of clock.
