Down translation:
The SN74LV3T99 device contains three independent configurable logic gates with 3-state outputs. Each gate has four inputs and performs the Boolean function Y = (A • C + B • C) ⊕ D. All inputs include Schmitt-triggers, eliminating any erroneous data outputs due to slow-edged or noisy input signals. The user can choose 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 input is designed with a reduced threshold circuit to support up translation when the supply voltage is larger than the input voltage. Additionally, the 5V tolerant input pins enable down translation when the input voltage is larger than the supply voltage. The output level is always referenced to the supply voltage (VCC) and supports 1.8V, 2.5V, 3.3V, and 5V CMOS levels.
