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
CC
operating range. The
device is specified to operate over the 1.65V to 5.5V V
CC
range. The inputs and outputs are high impedance when
V
CC
is 0V. Inputs tolerate voltages up to 5.5V
independent of V
CC
operating voltage.

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.
