74AC11138DR

Signal Switches, Multiplexers, Decoders Overview

The SN74AC11138DR is a decoder/demultiplexer from the Texas Instruments AC logic family, housed in an SOIC-16 surface-mount package. It features three address inputs and eight active-low outputs. The device operates within a supply voltage range of 2V to 6V and supports a maximum propagation delay of 10ns at 5V with 50pF load. It functions across an industrial temperature range of -40°C to +85°C.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides decoding or demultiplexing functionality via three binary address lines controlling eight distinct output channels.
• Outputs are active-low, ensuring logical inversion relative to the selected address input state.
• Incorporates dedicated enable inputs to control data flow and isolate outputs when disabled.

Signal Switches, Multiplexers, Decoders Applications

• Address decoding for memory subsystems
• Demultiplexing digital signals to peripheral devices
• Control signal distribution in embedded systems

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'DR' confirms the SOIC-16 tape-and-reel packaging configuration. Confirm the AC logic series designation matches system requirements for speed and voltage compatibility. Ensure the manufacturer identification aligns with Texas Instruments specifications for quality assurance.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a high-speed CMOS decoder with low power consumption is required. The AC series offers superior performance compared to standard HC logic while maintaining pin compatibility. Verify that the 2V to 6V operating range covers the target system's supply voltage variations.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN74ACxx series of high-speed CMOS logic devices. It serves as a functional equivalent to other industry-standard 3-to-8 line decoders. The AC series is designed for applications requiring faster switching speeds than standard TTL or basic CMOS families.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check for direct equivalents such as the SN74HC138 or SN74HCT138 if voltage levels differ. Verify pinout compatibility before substituting with non-TI manufacturers. Ensure the replacement maintains the same package type and electrical characteristics.
