Texas Instruments SN74AHC3G99/-Q1 Triple Multiple-Function Gates
Texas Instruments SN74AHC3G99/-Q1 Triple Multiple-Function Gates feature three independent configurable logic gates with 3-state outputs. Each gate has four inputs and implements the Boolean function Y = (A • C + B • C) ⊕ D. The inputs have Schmitt triggers, eliminating erroneous data outputs caused by slow-edged or noisy input signals. Users can choose from logic functions such as MUX, AND, OR, NAND, NOR, XOR, XNOR, inverter, and buffer by connecting the inputs A, B, C, and D appropriately.
The TI SN74AHC3G99-Q1 is AEC-Q100 qualified for automotive applications.
