Overview
The SN74LVC1G0832DBVR is a single 3-input positive AND-OR gate produced by Texas Instruments. This device is part of the LVC (Low-Voltage CMOS) family and is designed to operate over a wide voltage range from 1.65 V to 5.5 V. It is available in the SOT-23 (DBV) package, which is a compact and efficient packaging solution. The SN74LVC1G0832DBVR performs the Boolean function Y = (A • B) + C in positive logic and can be configured to act as a 2-input AND gate or a 2-input OR gate by tying specific inputs to GND or VCC.
