Overview
The SN74LVC86APWR is a quadruple 2-input exclusive-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 1.65V to 3.6V, making it versatile for various applications. The SN74LVC86APWR is available in several package options, including SOIC, SSOP, SOP, and TSSOP, among others.
The device performs the Boolean function Y = A ⊕ B or Y = AB + A'B in positive logic, which makes it useful for a variety of logical operations such as true/complement elements, parity generators, and logic identity elements. It is also capable of translating voltages between 3.3V and 5V systems, making it a valuable component in mixed-voltage environments.
