CP82C89

Specialized Overview

The CP82C89 is a bus arbiter and continuous signal generator manufactured by Harris Corporation. It operates on a static CMOS circuit design, providing high output current and capacitive drive capabilities to eliminate the need for additional bus buffering. The device supports a supply voltage range of 4.5V to 5.5V. It is housed in a 20-pin PDIP package and functions as an interface component for system bus arbitration.

Specialized Feature Summary

• Static CMOS circuit design ensures low power consumption and stable operation.
• High output current and capacitive drive capabilities reduce the requirement for external bus buffers.
• Integrated bus arbiter functionality facilitates seamless communication between systems and peripherals.

Specialized Applications

• System bus arbitration in computer architectures
• Continuous signal generation for peripheral interfaces
• Bus driver applications requiring high capacitive load handling

Specialized Procurement Notes

Verify the manufacturer origin, as Intersil Corporation also lists this part. Confirm RoHS compliance status, as sources indicate non-compliance. Ensure the specific package type matches requirements. Check for any ordering suffixes that may alter specifications. Validate the datasheet source against official Harris or Intersil documentation.

Specialized Selection Notes

Select this component for applications requiring integrated bus arbitration and signal generation without external buffering. Consider the static CMOS design for power efficiency. Verify compatibility with 4.5V to 5.5V supply rails. Ensure the 20-pin PDIP package fits the target PCB layout. Compare against modern equivalents if RoHS compliance is mandatory.
