Revised May 2003 NC7SZ175 TinyLogic UHS D-Type Flip-Flop with Asynchronous Clear General Description Features The NC7SZ175 is a single positive edge-triggered D-type CMOS Flip-Flop with Asynchronous Clear 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 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. A LOW input to Clear sets the Q output to LOW level. The Clear input is independent of clock. ■ Space saving SC70 6-lead package ■ Ultra small MicroPak leadless 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 NC7SZ175P6X MAA06A Z75 6-Lead SC70, EIAJ SC88, 1.25mm Wide 3k Units on Tape and Reel NC7SZ175L6X MAC06A C4 6-Lead MicroPak, 1.0mm Wide Package Description Supplied As 5k Units on Tape and Reel TinyLogic is a registered trademark of Fairchild Semiconductor Corporation.
