UHS Dual Buffer with 3-STATE Outputs
General Description
The NC7WZ241 is a Dual Non-Inverting Buffer with
3-STATE outputs. The output enable circuitry is organized
as active LOW for one buffer and active HIGH for the other
buffer, thus facilitating transceiver operation.
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.
