TinyLogic
UHS D-Type Latch with 3-STATE Output
General Description
The NC7SZ373 is a single positive edge-triggered D-type
CMOS Latch 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 V
CC
operating range. The
device is specified to operate over the 1.65V to 5.5V range.
The inputs and output are high impedance when V
CC
is 0V.
Inputs tolerate voltages up to 7V independent of V
CC
oper-
ating voltage. The latch appears transparent to the data
when Latch Enable (LE) is HIGH. When LE is LOW, the
data that meets the setup time is latched. The output toler-
ates voltages above V
CC
in the 3-STATE condition.
