MC74ACT151D

Overview

The MC74ACT151D is an octal multiplexer manufactured by onsemi, belonging to the ACT logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and features eight data inputs with three address select lines for channel selection. The device provides both true and complementary outputs in a non-inverting configuration. Packaged in a 16-pin SOIC format, it supports surface mount installation and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides simultaneous true and complementary output signals for selected data channels
• Integrates binary decoding circuitry to manage input selection via address lines
• Features high noise immunity characteristics inherent to the ACT logic family

Applications

• Data routing and switching in digital communication systems
• Address decoding for memory or peripheral selection
• Waveform generation and pulse width modulation circuits

Procurement Notes

Verify the specific datasheet version and environmental compliance status directly with onsemi before procurement. Confirm that the package marking and pinout align with design requirements. Ensure the component meets all relevant RoHS directives applicable to your region. Cross-reference the ordering suffix to confirm the exact packaging type and moisture sensitivity level required for assembly.

Selection Notes

Select this component when a single-channel selection from multiple sources is required using standard 5V logic levels. The ACT series offers faster propagation delays compared to older LS variants while maintaining CMOS power efficiency. Verify that the input voltage thresholds are compatible with the driving logic family in the system architecture.

Part Context

This part belongs to the 74ACT151 family of octal multiplexers produced by onsemi. It serves as a direct functional equivalent to other manufacturers' 74ACT151 devices, ensuring interoperability in mixed-vendor designs. The ACT series represents a performance tier between AC and HC technologies, offering improved speed without significant power penalty.

Replacement Considerations

Compatible substitutes include the SN74ACT151N (Texas Instruments) and the HCT74ACT151 equivalents if voltage compatibility allows. Verify pin-to-pin compatibility and electrical specifications against the original datasheet before substitution.
