SN74AHCT158PWR

Signal Switches, Multiplexers, Decoders Overview

The SN74AHCT158PWR is a quadruple 2-line to 1-line data selector/multiplexer designed for 4.5-V to 5.5-V VCC operation. It features TTL-voltage compatible inputs and inverted outputs. The device includes a common strobe (G) input that forces all outputs high when active, or routes selected data from two sources when inactive. It operates within an ambient temperature range of -40°C to +85°C and utilizes a TSSOP-16 package.

Signal Switches, Multiplexers, Decoders Feature Summary

• Features TTL-voltage compatible inputs for direct interfacing with standard logic families.
• Includes a common strobe input to globally control output states across all four channels.
• Provides inverted data routing from selectable dual sources to four independent outputs.
• Offers robust ESD protection exceeding JESD 22 standards for human-body and machine models.

Signal Switches, Multiplexers, Decoders Applications

• Data routing in digital signal processing systems
• Address decoding circuits
• Bus switching applications

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'PWR' corresponds to the tape-and-reel packaging format rather than tube packaging. Confirm the component status as Active Production on official Texas Instruments documentation before finalizing procurement plans. Ensure compatibility with the specified operating temperature range and voltage requirements.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for applications requiring quadruple multiplexing with TTL-compatible input levels. It is suitable for designs operating strictly between 4.5 V and 5.5 V. Consider the TSSOP-16 package constraints for PCB layout. Verify that the inverted output polarity aligns with downstream circuit requirements.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN74AHCT158 family of quadruple 2-line to 1-line data selectors. It is manufactured by Texas Instruments and falls under the AHCT logic series. The device is distinct from non-inverting variants and other multiplexer configurations within the broader logic IC portfolio.

Signal Switches, Multiplexers, Decoders Replacement Considerations

SN74AHCT158PW is a tube-packaged equivalent of the same functional device. SN74HC158D offers similar functionality but operates at different voltage ranges and lacks TTL input compatibility.
