ULP Dual Inverting Buffer
with 3-STATE Outputs
General Description
The NC7WP240 is a Du al Inverting Buffer with independent active LOW enables for the 3-STATE outputs. The
Ultra High Power device is ideal for applications where battery life is critical. This product is designed for ultra low
power consumption withi n the V

.
to 3.6V V
The internal circ uit is composed o f 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 optimi zed po wer and speed, and is fab ri cat ed
with an advanced CMOS technology to achieve best in
class speed operation while maintaining extremely low
CMOS power dissipation.
