SN74LVC1G08DBVR

The SN74LVC1G08DBVR from Texas Instruments is a single 2-input positive AND gate in the LVC logic family, performing the Boolean function Y = A * B in positive logic. Operating from 1.65V to 5.5V, it provides high output drive of +/-24 mA at 3.3V with low static power dissipation. The inputs are overvoltage tolerant to 5.5V independent of VCC, enabling use as a voltage translator in mixed-voltage systems. The Ioff feature ensures high-impedance state when VCC is 0V, supporting live insertion and partial-power-down applications. The compact SOT-23-5 package minimizes board space.

The SN74LVC1G08 implements a single 2-input AND gate using CMOS technology. The output Y goes high only when both inputs A and B are at logic high levels. The device uses a push-pull output stage that can both source and sink up to 24 mA at 3.3V, providing strong drive capability for capacitive loads or multiple downstream gates. The Ioff circuitry disconnects the output when VCC is at 0V, preventing damaging back-drive current in partial-power-down scenarios. The overvoltage-tolerant input structure allows input signals up to 5.5V regardless of the VCC level, facilitating mixed-voltage interfacing.
