SN74LVC1G3208-EP - Enhanced Product Single 3-Input Positive OR-AND Gate

This device is designed for 1.65-V to 5.5-V V_CC operation.

The SN74LVC1G3208 is a single 3-input positive OR-AND gate. It performs the Boolean function Y = (A + B) • C in positive logic.

By tying one input to GND or V_CC, the SN74LVC1G3208 offers two more functions. When C is tied to V_CC, this device performs as a 2-input OR gate (Y = A + B). When A is tied to GND, the device works as a 2-input AND gate (Y = B ⋅ C). This device also works as a 2-input AND gate when B is tied to GND (Y = A • C).

This device is fully specified for partial-power-down applications using I_off. The I_off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
