SN74LVC1G3208DBVT

单3输入正或与门 SINGLE 3-INPUT POSITIVE OR-AND GATE

DESCRIPON

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

The SN74LVC1G3208 device 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 device 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 B is tied device to GND also Y works = A ●asC. a 2-input AND gate when NanoStar™ and NanoFree™ package technology is a major breakthrough in IC packaging concepts, using the die as the package.

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.
