74AHC138PW-Q100J

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74AHC138PW-Q100J is a high-speed Si-gate CMOS 3-to-8 line decoder/demultiplexer with inverting outputs. It accepts three binary weighted address inputs (A0, A1, A2) and provides eight mutually exclusive outputs (Y0 to Y7). The device features two active LOW enable inputs (E1, E2) and one active HIGH enable input (E3). Qualified to AEC-Q100 Grade 1 standards, it operates within a supply voltage range of 2.0 V to 5.5 V for the AHC variant. It supports ambient temperatures from -40 °C to +125 °C and utilizes a TSSOP16 plastic thin shrink small outline package.
