74AHCT138T16-13

Signal Switches, Multiplexers, Decoders Overview

The 74AHCT138T16-13 is a 3-to-8 line decoder and demultiplexer manufactured by Diodes Incorporated. It operates within a supply voltage range of 4.5V to 5.5V and accepts a three-bit binary weighted address on inputs A0, A1, and A2. The device features two active LOW enable inputs (E1, E2) and one active HIGH enable input (E3). When enabled, it produces one active LOW output while the remaining seven outputs remain high. It is housed in a TSSOP-16 package.
