NC7SP57
Description
The NC7SP57 and the NC7SP58 are Universal Configurable 2-Input Logic Gates from Fairchild’s Ultra Low Power (ULP) Series of Tiny Logic. 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. Each device is capable of being configured for 1 of 5 unique 2-input logic functions. Any possible 2-input binatorial logic function can be implemented as shown in the Function Selection Table. Device functionality is selected by how the device is wired at the board level. Figure 1 through Figure 10 illustrate how to connect the NC7SP57 and NC7SP58 respectively for the desired logic function. All inputs have been implemented with hysteresis. The internal circuit is posed of a minimum of inverter stages including the output buffer, to enable ultra low dynamic power. The NC7SP57 and NC7SP58, for lower drive requirements, are uniquely designed for optimized power and speed, and are...
