Revised January 2001 NC7SZ374 TinyLogic UHS D-Type Flip-Flop with 3-STATE Output General Description Features The NC7SZ374 is a single positive edge-triggered D-type CMOS Flip-Flop 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–5.5V VCC range. The inputs and output are high impedance when VCC is 0V. Inputs tolerate voltages up to 7V independent of VCC operating voltage. This single flip-flop will store the state of the D input that meets the setup and hold time requirements on the LOW-to-HIGH Clock (CP) transition. 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 – 3V translation ■ Patented noise/EMI reduction circuitry implemented Ordering Code: Order Package Product Code Number Number Top Mark NC7SZ374P6 MAA06A Z74 6-Lead SC70, EIAJ SC88, 1.25mm Wide 250 Units on Tape and Reel NC7SZ374P6X MAA06A Z74 6-Lead SC70, EIAJ SC88, 1.25mm Wide 3k Units on Tape and Reel Package Description Supplied As Logic Symbol Pin Descriptions Pin Names Description D Data Input IEEE/IEC CP Clock Pulse Input OE Output Enable Input Q Flip-Flop Output Connection Diagrams Function Table Inputs CP X H = HIGH Logic Level L = LOW Logic Level Output D OE L L L H L H X L Qn X H Z Q (Top View) Pin One Orientation Diagram Z = High Impedance X = Immaterial Qn = No change in data AAA represents Product Code Top Mark - see ordering code Note: Orientation of Top Mark determines Pin One location.
