NC7WP125
TinyLogic ULP Buffer with 3-STATE Output
General Description
Features
The NC7WP125 is a dual buffer with 3-STATE output from
■ 0.9V to 3.6V VCC supply operation
■ 3.6V overvoltage tolerant I/O’s at VCC from 0.9V to 3.6V
■ tPD
Fairchild’s Ultra Low Power (ULP) series of TinyLogic
Ideal for applications where battery life is critical, this prod-
uct is designed for ultra low power consumption within the
.
VCC operating range of 0.9V to 3.6V.
3 ns typ for 3.0V to 3.6V VCC
The internal circuit is composed of a minimum of inverter
stages, including the output buffer, to enable ultra low static
and dynamic power.
4 ns typ for 2.3V to 2.7V VCC
5 ns typ for 1.65V to 1.95V VCC
6 ns typ for 1.40V to 1.60V VCC
10 ns typ for 1.10V to 1.30V VCC
26 ns typ for 0.90V VCC
The NC7WP125, 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.

Battery Life vs. V Supply Voltage
CC
TinyLogic ULP and ULP-A with up to 50% less power consumption can
extend your battery life significantly.
Battery Life = (Vbattery *Ibattery*.9)/(Pdevice)/24hrs/day
Where, Pdevice = (ICC * VCC) + (CPD + CL) * VCC2 * f
Assumes ideal 3.6V Lithium Ion battery with current rating of 900mAH and
derated 90% and device frequency at 10MHz, with CL = 15 pF load
