74AC151SCX

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74AC151SCX is an 8-input digital multiplexer housed in a 16-lead Small Outline Integrated Circuit (SOIC) package. It selects one data line from eight sources using three select inputs and provides both true and complementary outputs. The device operates within a supply voltage range of 2.0V to 6.0V and supports an operating temperature range of -40°C to +85°C. Outputs can source or sink up to 24 mA, and the quiescent supply current is reduced by 50% compared to standard AC logic.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides high-speed selection of one data line from eight sources
• Delivers both true and complementary output signals
• Capable of generating any logic function of four variables
• Features significantly reduced quiescent supply current

Signal Switches, Multiplexers, Decoders Applications

• Universal function generator for logic functions of four variables
• Data routing and signal selection systems
• Control information switching applications

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the ordering code includes the 'X' suffix to confirm tape and reel packaging. Confirm the specific manufacturer origin, as this part was originally distributed by Fairchild Semiconductor before acquisition by onsemi. Ensure the application environment remains within the specified -40°C to +85°C operating temperature limits.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when an 8-to-1 multiplexing function with complementary outputs is required. It is suitable for designs needing 24 mA drive capability and low power consumption. Verify that the system supply voltage falls between 2.0V and 6.0V. Consider the 74ACT151 if TTL-compatible input thresholds are necessary instead of standard AC levels.

Signal Switches, Multiplexers, Decoders Part Context

This component belongs to the 74AC family of high-speed CMOS logic devices. It implements a single pole, 8-position switch controlled by three select lines. The SOIC-16 package offers a narrow body form factor suitable for surface mount assembly. The device integrates buffering for all inputs and provides robust output drivers for direct interfacing with various logic families.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The 74ACT151SCX serves as a compatible alternative with TTL-compatible inputs. Other manufacturers produce equivalent 8-input multiplexers in the 74AC series. Verify pinout compatibility and electrical specifications such as propagation delay and output drive strength before substitution.
