ULP Dual Inverting Buffer
with 3-STATE Outputs
General Description
The NC7WP240 is a Dual Inverting Buffer with indepen-
dent active LOW enables for the 3-STATE outputs. The
Ultra High Power device is ideal for applications where bat-
tery life is critical. This product is designed for ultra low
power consumption within the V
CC
operating range of 0.9V
to 3.6V V
CC
.
The internal circuit is composed of a minimum of inverter
stages, including the output buffer, to enable ultra low static
and dynamic power.
The NC7WP240 for lower drive requirements, is uniquely
designed for optimized power and speed, and is fabricated
with an advanced CMOS technology to achieve best in
class speed operation while maintaining extremely low
CMOS power dissipation.
