Description

The NC7SZ19 is a 1-of-2 decoder with a common output enable. 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 broad V device is specified to operate over the 1.65V to 5.5V V range. The inputs and outputs are high impedance when V

is 0V. Inputs tolerate voltages up to 5.5V

Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
