74ACT153SCX

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74ACT153SCX is a dual 4-input multiplexer housed in a 16-lead Small Outline Integrated Circuit (SOIC) package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range of -40°C to +85°C. The device features common select inputs (S0, S1) and individual active-LOW enable inputs for each section. Outputs present data in the true form with a maximum propagation delay of 11.5 ns at 5.0 V.

Signal Switches, Multiplexers, Decoders Feature Summary

• Dual 4-input multiplexer architecture with common select lines
• Individual active-LOW enable inputs for independent section control
• TTL-compatible input thresholds for direct interface with TTL logic
• Outputs source and sink up to 24 mA

Signal Switches, Multiplexers, Decoders Applications

• Data routing between multiple sources
• Function generation of three-variable logic functions
• Implementation of 2-pole, 4-position switching operations

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'SCX' against current manufacturer documentation to confirm the SOIC-16 package type and tape-and-reel container format. Ensure compatibility with the required 4.5 V to 5.5 V supply voltage range and check for any recent product change notifications or lifecycle status updates from onsemi before finalizing procurement plans.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a dual multiplexer with TTL-compatible inputs is required. The ACT series offers reduced quiescent current compared to older AC variants while maintaining high-speed performance. Verify that the 16-lead SOIC package dimensions fit the PCB layout constraints and that the 24 mA output drive capability meets the load requirements of the downstream circuitry.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74ACT153 family of dual 4-input multiplexers manufactured by onsemi (formerly Fairchild Semiconductor). It is designed for high-speed digital applications requiring reliable data selection. The device implements standard 74ACT logic specifications, ensuring interoperability with other components in the same logic family within industrial and commercial temperature ranges.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Cross-reference with MC74ACT153DG or MC74ACT153DR2G for alternative packaging options such as tubes or different reel quantities. Verify pinout and electrical characteristics match exactly before substitution.
