UHS Dual Buffer with 3-STATE Outputs
General Description
The NC7WZ125 is a Dual Non-Inverting Buffer with inde-
pendent active LOW enables for the 3-STATE outputs. The
Ultra High Speed device is fabricated with advanced
CMOS technology to achieve superior switching perfor-
mance 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
operating range. The inputs and outputs are high imped-
ance when V
CC
is 0V. Inputs tolerate voltages up to 5.5V
independent of V
CC
operating range. Outputs tolerate volt-
ages above V
CC
when in the 3-STATE condition.
