SN74AHC138DGVR

Signal Switches, Multiplexers, Decoders Overview

The SN74AHC138DGVR is a single-function decoder/demultiplexer from the Texas Instruments AHC logic family. It converts three binary-coded address inputs into one of eight active-low outputs. The device operates within a supply voltage range of 2 V to 5.5 V and supports surface-mount installation in a TVSOP-16 package. It functions across an industrial temperature range of -40°C to +125°C, featuring low static power consumption and high noise immunity suitable for general-purpose digital applications.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides decoding or demultiplexing functionality by selecting one of eight outputs based on three-bit address inputs
• Includes three enable inputs that control device activation, allowing for system expansion when cascaded
• Outputs are active-low, ensuring clear state indication for connected logic circuits

Signal Switches, Multiplexers, Decoders Applications

• Address decoding in microprocessor-based systems
• Demultiplexing data streams in communication interfaces
• Memory chip select generation in embedded designs

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix DGVR corresponds to the TVSOP-16 package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the operating voltage range matches your system's power supply rails before integration.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a single 3-to-8 decoder with active-low outputs is required in a compact surface-mount form factor. The AHC series offers compatibility with standard CMOS logic levels while providing improved speed over older HC families. Consider the TVSOP-16 package constraints regarding thermal dissipation and board space availability.
