74F153SJ

Signal Switches, Multiplexers, Decoders Overview

The Fairchild Semiconductor 74F153SJ is a high-speed dual 4-input multiplexer belonging to the F/FAST series. It features common select inputs and individual enable inputs for each section, packaged in a 16-pin SOIC (SOP) format. The device operates with a nominal supply voltage of 5 V and supports synchronous operation. It is designed for bidirectional data selection tasks within TTL-compatible logic systems.

Signal Switches, Multiplexers, Decoders Feature Summary

• High-speed dual 4-input multiplexing capability
• Common select inputs shared across both sections
• Individual enable inputs for independent section control

Signal Switches, Multiplexers, Decoders Applications

• Parallel-to-serial data conversion circuits
• Data routing in digital communication systems
• Address decoding in memory architectures

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix SJ indicates the SOIC package variant when sourcing. Confirm RoHS compliance status as documentation varies by production batch. Ensure the supplier provides official Fairchild or onsemi datasheets to validate pinout and electrical characteristics against the original specification sheet before integration.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component for applications requiring fast switching speeds in dual-channel data selection. Compare propagation delays against standard LS or HC series if timing constraints are critical. Verify that the 16-pin SOIC footprint matches the target PCB layout requirements and that the 5V logic level compatibility aligns with the system voltage rails.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74F family of high-speed CMOS logic devices. It serves as a functional equivalent to other dual 4-line multiplexers like the 74LS153 but offers significantly faster performance. The device is widely used in legacy and modern digital designs requiring reliable data path management.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct substitutes include the 74F153 from various manufacturers. Verify pin compatibility and electrical specifications before swapping. Alternative packages such as DIP may be available under different suffixes.
