产品概览
The SN74LVC1G32DCKR is a single 2-input positive-OR gate from Texas Instruments designed for 1.65V to 5.5V operation. It performs the Boolean function Y = A + B in positive logic. With 5.5V overvoltage-tolerant inputs, 3.6ns max tpd, ±24mA output drive, down-translation support, and Ioff circuitry, it is ideal for signal combining and enabling logic in space-constrained designs using the SC70-5 package.
