74AHC138T16-13

Signal Switches, Multiplexers, Decoders Overview

The 74AHC138T16-13 is a 3-to-8 line decoder and demultiplexer manufactured by Diodes Incorporated in an advanced high-speed CMOS process. It accepts a three-bit binary weighted address on inputs A0, A1, and A2 to activate one of eight active-low outputs while keeping the others high. The device features two active-low enable inputs (E1, E2) and one active-high enable input (E3). It operates within a supply voltage range of 2.0 V to 5.5 V and supports Schmitt trigger action at all inputs for noise immunity.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides parallel expansion capabilities for creating 4-to-16 or 5-to-32 line decoders without additional logic parts
• Incorporates Schmitt trigger action at all inputs to ensure clean signal transitions
• Offers robust electrostatic discharge protection exceeding standard machine, human body, and charged device models
• Delivers low power consumption characteristics typical of CMOS technology

Signal Switches, Multiplexers, Decoders Applications

• Memory chip select decoding
• Demultiplexing data streams
• Single line peripheral control
• Converting serial bit streams from microcontrollers to control multiple peripheral lines

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific package suffix T16 corresponds to the TSSOP-16 housing required for your PCB layout. Confirm that the -13 suffix indicates tape and reel packaging with a quantity of 2500 units per reel. Ensure the design accounts for the RoHS compliant lead-free finish and green molding compound specifications defined by the manufacturer. Cross-reference the ordering information section of the datasheet to validate part availability and exact marking codes before finalizing procurement orders.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a compact 3-to-8 decoding solution is needed with active-low outputs. The TSSOP-16 package offers a smaller footprint compared to SO-16 alternatives. Consider the wide supply voltage range if the system operates between 2.0 V and 5.5 V. The inclusion of multiple enable lines makes it suitable for systems requiring cascaded expansion or complex enable logic without extra gates.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the 74AHC series of advanced high-speed CMOS logic devices produced by Diodes Incorporated. The 74AHC138 specifically functions as a 3-to-8 line decoder/demultiplexer. The T16-13 variant denotes the TSSOP-16 package type with tape and reel packaging. It is designed for general-purpose digital logic applications requiring reliable decoding and demultiplexing functions.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74AHC138S16-13 serves as a direct functional substitute, differing only in its SO-16 package instead of TSSOP-16. Verify pin compatibility and thermal requirements when swapping packages. Other manufacturers' 74AHC138 equivalents may be compatible if they meet the same electrical specifications and pinout definitions.
