SN74AHCT158DR

Signal Switches, Multiplexers, Decoders Overview

The SN74AHCT158DR is a quadruple 2-line to 1-line data selector/multiplexer designed for 4.5-V to 5.5-V VCC operation. It features a common strobe (G) input that forces all outputs high when asserted, and routes inverted data from selected sources when low. The device operates within an ambient temperature range of -40°C to +85°C. Propagation delays are specified at 7.5 ns maximum from A or B inputs to Y outputs, and 9.5 ns maximum from the A/B select input to Y outputs, measured with a 15-pF load.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides four independent multiplexing channels with inverted outputs
• Features TTL-voltage compatible inputs for direct interfacing
• Includes a common strobe control to disable outputs globally

Signal Switches, Multiplexers, Decoders Applications

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

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'DR' corresponds to the SOIC-16 tape and reel packaging configuration. Confirm the component status as active production against current Texas Instruments documentation. Ensure compatibility with standard surface-mount assembly processes by checking moisture sensitivity level ratings and peak reflow temperatures listed in the package materials information.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a quad multiplexer with inverted outputs is required for 5-V CMOS logic environments. The AHCT series ensures compatibility with TTL voltage levels while maintaining CMOS noise margins. Verify that the SOIC-16 package dimensions align with the target PCB footprint and that the operating temperature range meets the environmental requirements of the final application.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN74AHCT158 family of quadruple 2-to-1 multiplexers manufactured by Texas Instruments. It is part of the broader 74AHCT logic series, which bridges TTL and CMOS logic families. The 'DR' suffix specifically denotes the SOIC-16 surface-mount package variant supplied in tape and reel format for automated assembly.
