SN74AHC158D

Signal Switches, Multiplexers, Decoders Overview

The SN74AHC158D is a quadruple 2-line to 1-line data selector/multiplexer from the Texas Instruments AHC logic family. It operates within a supply voltage range of 2 V to 5.5 V and supports an operating temperature range of -40°C to +85°C. The device features four independent multiplexers with inverted outputs and a common strobe (G) input that disables all outputs when high. It utilizes a 16-pin SOIC package.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides four independent 2-to-1 data selection paths with inverted outputs
• Features a common strobe input for global output control
• Compatible with CMOS and LVTTL logic levels across the specified voltage range

Signal Switches, Multiplexers, Decoders Applications

• Data routing in digital systems
• Signal path selection
• Address decoding applications

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix against the current Package Option Addendum, as the 'D' tube variant is listed as obsolete while the 'DR' tape-and-reel version remains active. Confirm RoHS compliance and lead finish details directly with the manufacturer or authorized distributors prior to procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for designs requiring multiple independent signal selectors within a single integrated circuit. Ensure the application voltage falls between 2 V and 5.5 V. Verify that the required propagation delay characteristics align with the system timing constraints at the target supply voltage.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN54/74AHC158 series of quadruple 2-line to 1-line data selectors. The 'SN74' prefix indicates commercial grade availability, while the 'AHC' designation signifies advanced high-speed CMOS technology designed for low power consumption and high-speed operation compared to legacy families.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The SN74AHC158DR is the active tape-and-reel equivalent of the obsolete SN74AHC158D tube variant. Other pin-compatible alternatives include the SN74AHC158DBR (SSOP) and SN74AHC158PWR (TSSOP), provided the package footprint matches the design requirements.
