NC7SP34 TinyLogic ULP Single Buffer
General Description
The NC7SP34 is a single buffer from Fairchild’s Ultra Low Power (ULP) Series of TinyLogic. Ideal for applications where battery life is critical, this product is designed for ultra low power consumption within the VCC operating range of 0.9V 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. The NC7SP34, 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. VCC Supply Voltage
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 + C L) * 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

Note 1: Absolute Maximum Ratings: are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation. Note 2: IO Absolute Maximum Rating must be observed. Note 3: Unused inputs must be held HIGH or LOW. They may not float.
