74AC11138NSR

Signal Switches, Multiplexers, Decoders Overview

The Texas Instruments 74AC11138NSR is a high-speed CMOS decoder and demultiplexer housed in a 16-pin SOIC surface-mount package. It functions as a 3-line to 8-line decoder/demultiplexer within the AC logic series. The device operates with a supply voltage range of 3 V to 5.5 V and supports an operating temperature range from -40 °C to +85 °C. Key electrical characteristics include a propagation delay of 8.8 ns, low-level output current of 24 mA, and high-level output current of -24 mA. It incorporates three enable inputs to simplify design.
