SN74AHC158PW

Signal Switches, Multiplexers, Decoders Overview

The SN74AHC158PW is a quadruple 2-line to 1-line data selector/multiplexer from Texas Instruments, housed in a 16-pin TSSOP package. 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 input. Electrical characteristics include propagation delays ranging from 7.5 ns to 19.5 ns depending on load capacitance and voltage, with output currents up to ±8 mA at 5 V.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides four independent 2-to-1 data selection paths with inverted outputs
• Features a common strobe input that forces all outputs high when active
• Supports wide supply voltage operation from 2 V to 5.5 V
• Includes ESD protection exceeding JESD 22 standards for human-body and charged-device models

Signal Switches, Multiplexers, Decoders Applications

• Data routing in digital logic circuits
• Signal selection in microprocessor systems
• Address decoding applications

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the TSSOP-16 tube packaging configuration as listed in the manufacturer's ordering information. Confirm RoHS compliance status and lead finish details via the latest Package Option Addendum before procurement. Ensure the component meets the required industrial temperature range specifications for the intended application environment.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when multiple independent signal paths require selection with a unified control mechanism. The AHC logic family offers CMOS compatibility and low power consumption suitable for battery-operated devices. Consider the TSSOP package dimensions if board space is constrained compared to SOIC or SSOP alternatives.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN74AHC158 series of quadruple 2-line to 1-line data selectors. It is functionally compatible with other variants in the series such as SN74AHC158DR (SOIC) and SN74AHC158DBR (SSOP), differing primarily in package type and manufacturing lot characteristics rather than internal circuitry.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct pin-compatible replacements include SN74AHC158DR and SN74AHC158DBR. Verify package footprint compatibility when substituting between TSSOP, SOIC, and SSOP formats.
