74ACT151SJX

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74ACT151SJX is an 8-input digital multiplexer in the 74ACT logic family, housed in a 16-lead Small Outline Package (SOP). It operates within a supply voltage range of 4.5 V to 5.5 V and supports temperatures from -40°C to +85°C. The device features TTL-compatible inputs, outputs capable of sourcing or sinking 24 mA, and provides both true and complementary data outputs.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides high-speed selection of one data line from eight sources using three select inputs.
• Features TTL-compatible inputs for direct interfacing with standard logic circuits.
• Outputs deliver robust drive capability by sourcing and sinking up to 24 mA.
• Includes both true and complementary outputs to support diverse logic requirements.

Signal Switches, Multiplexers, Decoders Applications

• Universal function generator for implementing logic functions of four variables
• Data routing and signal switching in digital systems
• Address decoding and control information selection

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the ordering code includes the 'X' suffix to confirm tape and reel packaging availability. Ensure the SOP package variant matches the specific design footprint requirements. Confirm compliance with RoHS directives and check for any recent product change notifications before finalizing procurement specifications.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when an 8-to-1 multiplexing function is required with TTL input compatibility. The ACT series offers reduced quiescent current compared to older standards while maintaining high output drive strength. Verify that the operating temperature range and supply voltage constraints align with the target system environment.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74AC/ACT151 family of 8-input multiplexers originally documented by Fairchild Semiconductor. The 74ACT variant specifically ensures compatibility with TTL logic levels. The SJX designation indicates the SOP package configuration with tape and reel shipping options.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Cross-reference with other 74ACT151 variants from different manufacturers to ensure pinout and electrical parameter compatibility. Verify package dimensions and lead spacing if substituting with non-equivalent SOP packages.
