General Description
The NC7WZ241 is a Dual Non-Inverting Buffer with
3-STATE outpu ts. 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 wit h advanced
CMOS technology to achieve superior switching performance with high output drive while maintaining low static
power dissipation over a br oad V
device is specified to o perate over the 1.65V to 5.5V V
operating range. Th e inputs and outputs are h igh imped-
ance when V
