74AHC138D,112

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74AHC138D,112 is a high-speed silicon-gate CMOS 3-to-8 line decoder and demultiplexer. It accepts three binary weighted address inputs (A0, A1, A2) and provides eight mutually exclusive outputs (Y0 to Y7). The device operates with a supply voltage range of 2V to 5.5V and features an industrial temperature rating from -40°C to +125°C. It utilizes a 16-pin SOIC package with a width of 3.90mm. Outputs are active LOW when selected, and the component includes Schmitt-trigger action on all inputs for noise immunity.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix '112' against official Nexperia documentation to confirm the tape and reel packaging configuration, as this designation typically indicates bulk or tube packing rather than standard reel quantities. Confirm that the RoHS3 compliance status aligns with current environmental regulations for your target market before finalizing procurement orders.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when TTL-compatible input levels are not required but CMOS compatibility is essential. The 74AHCT variant is necessary if direct interfacing with TTL logic levels is needed instead. Ensure the design accommodates the specified operating voltage range and verify that the 16-SOIC package dimensions fit the available PCB real estate constraints.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74AHCx138 series of decoders manufactured by Nexperia. These devices are pin-compatible with Low Power Schottky TTL (LSTTL) standards. The series is designed for high-speed applications and complies with JEDEC standard No. 7A specifications for CMOS logic devices.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct substitutes include the 74AHC138S16-13 from Diodes Incorporated. Other compatible options within the same family include the 74AHC138PW,118, which shares identical logical functions but may differ in packaging format.
