TinyLogic
ULP Single Buffer
General Description
The NC7SP34 is a single buffer fr om Fairchild’s Ultra Low
Power (ULP) Serie s of TinyLogic
where battery life is critical, this product is designed for
ultra low power consumption within the V
range of 0.9V to 3.6V V
CC
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 NC7SP34, for lower drive requirements, is uniq uely
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.
. Ideal for applicat ions
