SN74AHC158DR

Signal Switches, Multiplexers, Decoders Overview

The SN74AHC158DR is a quadruple 2-line to 1-line data selector/multiplexer manufactured by Texas Instruments in an SOIC-16 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 a common strobe input that forces all outputs high when active, allowing selection from two sources when inactive. It provides inverted data outputs with a maximum propagation delay of 11.5 ns at 3.3 V and 7.5 ns at 5 V under specified load conditions.

Signal Switches, Multiplexers, Decoders Feature Summary

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'DR' corresponds to the SOIC-16 tape and reel packaging configuration. Confirm RoHS compliance status and lead finish details via the latest TI Package Option Addendum. Ensure the procurement source provides valid traceability documentation consistent with Texas Instruments standard warranty terms.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when multiple independent 2-to-1 signal paths are required within a single integrated circuit. Consider the AHC logic family for its CMOS compatibility and low power consumption characteristics. Evaluate the package thermal impedance and pinout requirements against the target PCB layout constraints before finalizing the design.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN74AHC158 series of quadruple multiplexers designed for general-purpose digital applications. It is distinct from the SN74AHCT158, which requires 5-V compatible inputs. The DR suffix specifically denotes the SOIC surface-mount package variant intended for automated assembly processes.

Signal Switches, Multiplexers, Decoders FAQ

How does the common strobe input affect the outputs?

When the strobe input is high, all four outputs are forced to a high state regardless of the address or data inputs. When the strobe is low, the selected data inputs are routed to the corresponding outputs.

What is the logic function provided by this device?

The SN74AHC158 provides inverted data outputs. The truth table indicates that the selected input is passed through an inverter before appearing at the output Y.
