UHS D-Type Flip-Flop
with Asynchronous Clear
General Description
The NC7SZ175 is a s ingle positive edge -triggered D-type
CMOS Flip-Flop with Asynchronous Clear from Fairchild’s
Ultra High Speed Series of TinyLogic
SC70 6-lead package. The device is fabricated with
advanced CMOS technolog y to achieve ultra high speed
with high output drive while maintaining low static power
dissipation over a very broad V
device is specified to o perate over the 1.65V to 5.5V V
range. The inputs a nd output are high impedance wh en

operating voltage. This single flip-flop will store the
CC
state of the D input that mee ts 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.
