Revised January 2001 NC7SZ373 TinyLogic UHS D-Type Latch with 3-STATE Output General Description Features 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. ■ Space saving SC70 6-lead package ■ 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 ■ Power down high impedance inputs/output ■ Overvoltage tolerant inputs facilitate 5V to 3V translation ■ Patented noise/EMI reduction circuitry implemented Ordering Code: Order Package Product Code Number Number Top Mark NC7SZ373P6 MAA06A Z73 6-Lead SC70, EIAJ SC88, 1.25mm Wide 250 Units on Tape and Reel NC7SZ373P6X MAA06A Z73 6-Lead SC70, EIAJ SC88, 1.25mm Wide 3k Units on Tape and Reel Package Description Logic Symbol Pin Descriptions Pin Names Description D Data Input LE Latch Enable Input OE Output Enable Input Q Supplied As IEEE/IEC Latch Output Connection Diagrams Function Table Inputs Output LE D OE H L L L H H L H Q L X L Qn-1 (Top View) X X H Z Pin One Orientation Diagram H = HIGH Logic Level X = Immaterial L = LOW Logic Level Z = HIGH Impedance Qn-1 = Previous state prior to HIGH-to-LOW transition of latch enable AAA = Product Code Top Mark - see ordering code Note: Orientation of Top Mark determines Pin One location.
