Overview
The MC74AC157M is a quad 2-input multiplexer manufactured by onsemi, belonging to the 74AC logic series. It features four independent multiplexers within a single package, each selecting between two data inputs based on a common select line. The device operates with a supply voltage range of 2V to 6V and supports surface-mount installation in a 16-SOIC package. It provides non-inverted outputs and includes an active-low output enable input for controlling data flow.
Feature Summary
- Provides four independent 2-to-1 multiplexing channels
- Operates across a wide 2V to 6V supply voltage range
- Features active-low output enable for controlled data routing
- Delivers non-inverted data outputs
Applications
- Data routing in digital systems
- Signal selection circuits
- Bus switching applications
Procurement Notes
Verify the specific suffix 'M' against the manufacturer's official datasheet to confirm the exact package type and tape/reel specifications. Ensure the component meets required RoHS compliance standards for your assembly process. Cross-reference the ordering information with current distributor catalogs to confirm availability and lead times before finalizing procurement plans.
Selection Notes
Select this component when a compact solution for multiple parallel data paths is required. The AC series offers higher speed than HC variants while maintaining CMOS compatibility. Verify that the 16-SOIC package fits the PCB footprint constraints and that the 2V-6V operating range aligns with the system power supply design.
Part Context
This part belongs to the 74AC157 family of high-speed CMOS multiplexers. It serves as a functional equivalent to other industry-standard quad 2-input muxes but is specifically optimized by onsemi for performance within the AC logic family. It is designed for general-purpose digital logic applications requiring reliable signal selection.
Replacement Considerations
Check for direct pin-compatible alternatives such as MC74AC157DR2G or MC74AC157DG from onsemi. Other manufacturers may offer compatible parts like the SN74AC157, but verify electrical characteristics and package dimensions carefully.
