General Description
The NC7SZ373 is a s ingle positive edge -triggered D-type
CMOS Latch with 3-STATE output 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 operate over the 1.65V to 5.5V range.
The inputs and output are high impedance when V
Inputs tolerate voltages up to 7V inde pe nde nt o f V
ating voltage. The latc h appears transparent to the data
when Latch Enable (LE ) is HIGH. When LE is LOW, the
data that meets the set up ti me is l a tche d. Th e o utp ut tolerates voltages above V
UHS D-Type Latch with 3-STAT E Output
