The NC7SZ14 is a single Inverter with Schmitt Trigger input from Fairchild's Ultra High Speed Series of TinyLogic®. 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 input and output are high impedance when VCC is 0V. Inputs tolerate voltages up to 6V independent of VCC operating voltage.
The Fairchild NC7S14M5X is a TinyLogic Ultra High Speed CMOS Single Schmitt Inverter It comes in a 5-Lead SC70 Tape and Reel Package.
