Overview
The 74LVC138APW-Q100J is a 3-to-8 line decoder/demultiplexer integrated circuit produced by Nexperia USA Inc. This device decodes three binary weighted address inputs (A0, A1, and A2) to eight mutually exclusive outputs (Y0 to Y7). It features three enable inputs (E1, E2, and E3), allowing for easy parallel expansion and use as an eight-output demultiplexer. The 74LVC138APW-Q100J is designed for use in mixed 3.3 V and 5 V environments and is suitable for various applications, including automotive and industrial sectors, due to its AEC-Q100 qualification.
