Overview
The 74HC138D-Q100,118 is a 3-to-8 line inverting decoder/demultiplexer 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 demultiplexing capabilities. The 74HC138D-Q100,118 is part of the 74HC series and is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), making it suitable for automotive applications. It operates with a wide supply voltage range from 2V to 6V and is known for its CMOS low power dissipation and high noise immunity.
