74ACT153SC

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74ACT153SC is a high-speed dual 4-input multiplexer housed in a 16-lead Small Outline Integrated Circuit (SOIC) package. It features common select inputs and individual active-LOW enable inputs for each section, allowing independent strobing of outputs. The device operates within a supply voltage range of 4.5V to 5.5V and supports TTL-compatible inputs. Outputs present data in the true form with source/sink capabilities of 24 mA. Propagation delays are typically 7.0 ns at 5.0V with 50 pF load.

Signal Switches, Multiplexers, Decoders Feature Summary

• Dual 4-input multiplexer architecture with common select lines
• Individual active-LOW enable inputs for independent output control
• TTL-compatible input thresholds for direct interface with logic families
• High-speed operation with buffered non-inverted outputs

Signal Switches, Multiplexers, Decoders Applications

• Data routing between multiple sources to single destinations
• Implementation of Boolean functions using variable inputs
• Parallel-to-serial conversion circuits
• Address decoding in memory systems

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'SC' corresponds to the 16-lead SOIC JEDEC MS-012 narrow body package. Confirm that the ACT variant meets the required 4.5V to 5.5V operating voltage range and TTL input compatibility. Ensure the manufacturer documentation aligns with the current product lifecycle status before finalizing procurement specifications.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual independent 4-to-1 multiplexing is required within a single package. The ACT series provides faster switching speeds compared to standard AC variants while maintaining CMOS power efficiency. Verify that the 16-lead SOIC footprint fits the available PCB space and that the 24 mA output drive capability satisfies the load requirements of the connected circuitry.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74AC/ACT logic family, designed for high-speed digital applications. The 74ACT153 specifically implements the dual 4-input multiplexer function. It is manufactured under the Fairchild Semiconductor brand, which is now part of onsemi. The SC suffix denotes the specific surface-mount package type used for this device.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Cross-reference with MC74ACT153DG or MC74ACT153DR2G from onsemi for equivalent functionality. Check pinout compatibility and electrical characteristics against other 74ACT153 derivatives from different manufacturers to ensure interchangeability without circuit modification.
