74AC11158N

Signal Switches, Multiplexers, Decoders Overview

The DM74AS158N is a quad 2-input multiplexer belonging to the AS series, manufactured by Rochester Electronics. It features four independent functions, each selecting one of two data inputs for a single inverted output based on select lines. The device utilizes TTL logic levels and is housed in a 16-pin plastic DIP package with a 0.300-inch width. It operates within a maximum temperature range up to 70 °C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and date codes upon receipt. Ensure storage conditions meet semiconductor handling standards to prevent moisture damage or electrostatic discharge during installation and testing procedures.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when designing systems requiring multiple independent 2-input selectors using TTL-compatible logic. Consider the PDIP16 package constraints for board layout. Verify that the 70 °C maximum operating temperature aligns with the intended environmental conditions of the final application assembly.

Signal Switches, Multiplexers, Decoders Part Context

Rochester Electronics specializes in sourcing and distributing obsolete and hard-to-find semiconductors. This part represents a continuation of legacy Texas Instruments designs, specifically the DM74AS158, ensuring availability for existing manufacturing lines that require these specific vintage logic components.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct equivalents include the original DM74AS158 from Texas Instruments. Other AS series multiplexers may serve as functional substitutes if pin compatibility and electrical characteristics match the design requirements.
