74AC11138PWR

Signal Switches, Multiplexers, Decoders Overview

The Texas Instruments 74AC11138PWR is a high-speed CMOS decoder and demultiplexer housed in a 16-TSSOP surface-mount package. It functions as a 3-line to 8-line decoder/demultiplexer with three enable inputs. The device operates within a supply voltage range of 3 V to 5.5 V and supports a propagation delay of 8.8 ns at 5 V. It features inverting outputs and is designed for applications requiring high-speed memory decoding and data transmission systems.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix PWR indicates the TSSOP-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the ordering part number matches the required logic family and pin configuration for your PCB layout.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a 3-to-8 line decoding function with active-low outputs is required in a surface-mount application. The AC series offers higher speed than standard 74LS equivalents. Verify that the 3 V to 5.5 V operating voltage range aligns with the target system power rails and that the TSSOP-16 footprint fits the board design constraints.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the Texas Instruments 74AC logic family, which provides advanced CMOS performance. The 74AC11138 is the surface-mount (PWR) version of the 74AC11138N, differing primarily in packaging type while maintaining identical logical functionality and electrical characteristics defined by the SN54/74AC specification.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74AC11138N serves as a direct PDIP equivalent. For lead-free variants, check for suffixes such as E4 if available from the manufacturer. Cross-reference with other 74AC11138 derivatives ensuring the output polarity and enable logic remain compatible.
