SN74AHCT158NSR

Signal Switches, Multiplexers, Decoders Overview

The SN74AHCT158NSR 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 controls output states; when high, outputs are high, and when low, a 4-bit word is selected from two sources. The device provides inverted data outputs. It operates within an ambient temperature range of -40°C to +85°C and utilizes a 16-pin NS (SOP) surface-mount package.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides four independent multiplexing channels with inverted outputs
• Features a single common strobe control input for simultaneous channel selection
• Inputs are TTL-voltage compatible for direct interfacing with TTL logic systems

Signal Switches, Multiplexers, Decoders Applications

• High-performance memory decoding applications
• Data routing in digital systems
• Parallel-to-serial conversion circuits

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'NSR' corresponds to the SOP package and tape-and-reel carrier format. Confirm the operating temperature grade matches the system requirements (-40°C to +85°C). Ensure the datasheet revision SCLS348J aligns with the manufacturing batch specifications.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when multiple independent 2-to-1 signal paths are required within a single integrated circuit. The AHCT logic series ensures compatibility with standard TTL voltage levels while maintaining CMOS power efficiency. Verify that the SOP package thermal impedance meets the board's heat dissipation capabilities.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN74AHCT158 family of quadruple multiplexers manufactured by Texas Instruments. It is distinct from other variants such as the SOIC or TSSOP packages based on its specific SOP physical form factor. The device serves as a core switching element in digital logic architectures requiring parallel data path management.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct substitutes include SN74AHCT158DR (SOIC), SN74AHCT158PWR (TSSOP), and SN74AHCT158DBR (SSOP). These alternatives share identical electrical characteristics but differ in physical package dimensions and pin spacing.
