SN74LVC1G99 Multi-Function Gates

Texas Instruments SN74LVC1G99 Ultra-Configurable Multi-Function Gates provides configurable multiple functions with a 3-state output. When the output-enable input is high, the output is disabled. The output state is determined by 16 patterns of 4-bit input when the output enable is low. Logic functions available include MUX, AND, OR, NAND, NOR, XOR, XNOR, inverter, and buffer, with all inputs able to be connected to V_CC or G_ND. The Schmitt action provides different input threshold levels for positive-going (V_T+) and negative-going (V_T–) signals, although the device can function as an independent inverter. The OE should be tied to V_CC through a pullup resistor to ensure the high-impedance state during power up or power down. The I_off enables the device to be ideal for partial power-down applications.
