| NC7SZ373 TinyLogic UHS D-Type Latch with 3-STATE Output June 1998 Revised May 2003 NC7SZ373 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 VCC operating range. The device is specified to operate over the 1.65V to 5.5V range. The inputs and output are high impedance when VCC is 0V. Inputs tolerate voltages up to 7V independent of VCC operating 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 tolerates voltages above VCC in the 3-STATE condition.
