CA0124M

Overview

The CA0124M is a high-speed CMOS analog multiplexer manufactured by Intersil. It features four independent single-pole double-throw (SPDT) switches, providing a total of eight input channels and two common outputs. The device operates with a single supply voltage ranging from +4.5V to +36V or dual supplies from ±2.25V to ±18V. It supports both TTL and CMOS logic inputs for control compatibility. Key electrical characteristics include low on-resistance and minimal channel-to-channel matching variation. The package type is a standard 16-pin DIP.

Feature Summary

• Four independent SPDT analog switches
• Compatible with TTL and CMOS logic levels
• Low on-resistance and flat response
• Single or dual power supply operation

Applications

• Data acquisition systems
• Signal routing in instrumentation
• Audio switching applications
• Process control systems

Procurement Notes

Verify the specific suffix 'M' indicates the military or extended temperature grade if required by your design specifications. Confirm the package style matches your PCB footprint requirements. Check for RoHS compliance status as manufacturing processes may vary by production batch. Ensure the supplier provides valid traceability documentation for critical applications.

Selection Notes

Select this component when multiple signal sources need to be routed to a single destination with low distortion. Consider the on-resistance value for signal integrity requirements at higher frequencies. Evaluate the supply voltage range against your system's available power rails. Compare leakage current specifications if handling high-impedance signals.

Part Context

Intersil was acquired by Renesas Electronics. This part belongs to the legacy CMOS analog switch family. It serves as a direct replacement for older Motorola MC14051B equivalents in many designs. The technology represents standard bulk CMOS processes suitable for general-purpose analog switching tasks.

Replacement Considerations

Check for pin-compatible alternatives from Texas Instruments or Analog Devices. Verify that substitute parts meet the same voltage and current ratings. Ensure logic level compatibility remains consistent across potential replacements.
