74AC151SJ

Signal Switches, Multiplexers, Decoders Overview

The Fairchild Semiconductor 74AC151SJ is an AC series, 8-line to 1-line multiplexer featuring complementary outputs. It utilizes a PDSO-16 plastic package with a width of 0.300 inches (JEDEC EIAJ standard). The device operates within a supply voltage range of 2V to 6V and supports an operating temperature range from -40°C to 85°C. Electrical characteristics include a maximum propagation delay of 15 ns and a load capacitance rating of 50 pF.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides high-speed selection of one data line from eight sources
• Delivers both true and complementary output signals
• Utilizes balanced CMOS push-pull output structure

Signal Switches, Multiplexers, Decoders Applications

• Boolean function generation for logic variables
• Parallel-to-serial data conversion
• Data source selection in digital systems

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific manufacturer origin, as Texas Instruments produces the CD74AC151 variant while Fairchild/ON Semiconductor produces the 74AC151. Confirm that the suffix 'SJ' corresponds to the specified 16-pin SOIC JEDEC package. Ensure the component meets the required AC series electrical specifications rather than ACT or HC variants.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when an 8-input multiplexer with complementary outputs is required. The AC series offers significantly reduced power consumption compared to bipolar F, AS, and S families while maintaining comparable speed. Verify that the 1.5V to 6V operating range aligns with the system's power supply constraints.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74AC logic family, characterized by high-speed operation and low power dissipation. It serves as a functional equivalent to other 8-input multiplexers such as the 74LS151, though with different electrical characteristics. The device is designed for applications requiring fast switching and balanced drive capabilities.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Compatible substitutes include the CD74AC151 from Texas Instruments and the 74ACT151SC from Fairchild/ON Semiconductor. Verify pinout compatibility and ensure the replacement matches the required AC series performance levels.
