描述 Description

The NC7WZ17 is a dual buffer with Schmitt trigger inputs from Fairchild's Ultra-High Speed (UHS) series of TinyLogic? products. 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 outputs are high-impedance when VCC is 0V. Inputs tolerate voltages up to 7V, independent of VCC operating voltage. Schmitt trigger inputs achieve 1V typical hysteresis between the positive- and negativegoing input threshold voltage at 5V.
