SN74AHC158NSR

Signal Switches, Multiplexers, Decoders Overview

The SN74AHC158NSR is a quadruple 2-line to 1-line data selector/multiplexer from Texas Instruments, designed for operation within a 2-V to 5.5-V VCC range. It features a common strobe (G) input that forces all outputs high when asserted; otherwise, it routes inverted data from selected sources to four outputs based on the A/B select line. The device operates across an industrial temperature range of -40°C to +85°C and utilizes a 16-pin NS (SOP) package.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'NSR' corresponds to the SOP package and tape-and-reel configuration. Confirm the component meets RoHS compliance standards as indicated in the manufacturer's documentation. Ensure the operating environment remains within the specified -40°C to +85°C temperature limits for reliable performance.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when quadruple multiplexing with inverted outputs is required. It is suitable for designs needing a common strobe function and compatibility with both 3.3-V and 5-V logic families. Consider the SOP package constraints regarding thermal impedance and board space availability during integration.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN74AHC158 family of quadruple 2-line to 1-line data selectors. It shares functional characteristics with other devices in the series but differs in packaging and reel specifications. The 'NSR' designation specifically identifies the surface-mount SOP variant supplied in tape-and-reel format for automated assembly.

Signal Switches, Multiplexers, Decoders FAQ

How does the common strobe input affect the outputs?

When the strobe (G) input is high, all four outputs are forced to a high state regardless of the data inputs or select line.

What is the logic level of the outputs?

The SN74AHC158 provides inverted data at its outputs relative to the selected input source.
