NC7SZ27 TinyLogic UHS 3-Input NOR Gate
General Description
The NC7SZ27 is a single 3-Input NOR Gate 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 inputs and output are high impedance when VCC is 0V. Inputs tolerate voltages up to 7V independent of VCC operating voltage.
