SN74AHC158NSRE4

Signal Switches, Multiplexers, Decoders Overview

The SN74AHC158NSRE4 is a quadruple 2-line to 1-line data selector/multiplexer from Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features a common strobe input that forces all outputs high when active. The device provides inverted data outputs and supports an operating temperature range of -40°C to +85°C. It utilizes a 16-pin NS (SOP) package.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'E4' against current TI documentation to confirm material composition and environmental compliance status, as suffixes can indicate variations in lead finish or RoHS designation. Ensure the NS package type matches the intended PCB footprint requirements.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for designs requiring multiple independent 2-to-1 data paths controlled by a single enable signal. The AHC series offers CMOS performance with TTL-compatible inputs. Verify that the required propagation delay and output drive capabilities meet the system timing specifications under the target load conditions.

Signal Switches, Multiplexers, Decoders Part Context

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 high regardless of the data inputs. When low, the selected data is routed to the outputs.

What is the logic level of the outputs?

The SN74AHC158NSRE4 provides inverted data at its outputs relative to the selected input source.
