Down translation:
The SN74LV3T99-Q1 device features configurable multiple functions with a 3-state output. The output is disabled when the output-enable (OE) input is high. When OE is low, 16 patterns of the 4-bit input determines the output state. The user can choose logic functions, such as MUX, AND, OR, NAND, NOR, XOR, XNOR, inverter, and buffer. All inputs can be connected to VCC or GND.
To put the device in the high-impedance state during power up or power down, tie OE to VCC through a pullup resistor; the current-sinking capability of the driver determines the minimum value of the resistor.
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.
