DESCRIPTION/ORDERING INFORMATION

This device is designed for 1.65-V to 5.5-V VCC

operation.

The SN74LVC1G3208-Q1 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 VCC, the

SN74LVC1G3208-Q1 offers two more functions. When C is tied to VCC, 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 Ioff. The Ioff circuitry disables the

outputs, preventing damaging current backflow

through the device when it is powered down.
