Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CPD' against official Harris documentation to confirm the package type and temperature range. Ensure the component meets RoHS compliance requirements if applicable to your project, as older CMOS parts may not adhere to current environmental standards. Cross-reference the datasheet for electrical characteristics to ensure compatibility with your system's voltage levels and timing constraints.

Analog To Digital Converters (ADC) Selection Notes

Select this component when interfacing 8-bit microprocessors with serial devices requiring dedicated hardware flow control. It is suitable for designs needing high-speed serial data transfer without CPU intervention. Consider the PDIP package constraints for PCB layout and thermal management. Verify that the 16 MHz clock requirement aligns with your system's oscillator capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Harris serial I/O controller family, designed to offload serial communication tasks from the main processor. It complements other Harris peripheral controllers in embedded systems. The CPD variant specifically denotes the plastic DIP packaging and commercial/industrial temperature rating. It serves as a bridge between parallel microprocessor buses and serial peripheral devices.

Analog To Digital Converters (ADC) Replacement Considerations

Check for pin-compatible alternatives from manufacturers like National Semiconductor or Texas Instruments that offer similar 80C86 bus compatibility. Verify that any substitute maintains the same 28-pin PDIP footprint and supports the required 0.125 MBps data rate. Ensure the replacement device offers equivalent internal RAM capacity and asynchronous protocol support.
