CA0555E

Overview

The CA0555E is a bipolar timer integrated circuit manufactured by Harris Corporation. It is housed in an 8-pin metal can package (CAN8) and operates within a temperature range of -55 °C to 125 °C. The device utilizes bipolar technology and features tin/lead terminal plating. It is classified as a military-grade component, though it is noted as not being RoHS compliant.

Feature Summary

• Bipolar timer functionality
• Military temperature rating
• Metal can packaging

Applications

Procurement Notes

Verify the specific suffix 'E' against official Harris or Renesas documentation to confirm if it denotes a distinct electrical variant or merely a packaging/tracking code. Confirm RoHS non-compliance status for regulatory requirements. Ensure the military temperature grade (-55 °C to 125 °C) aligns with system environmental specifications before procurement.

Selection Notes

Select this component when a robust, bipolar timer is required for high-temperature environments. The metal can package offers superior thermal dissipation and hermetic sealing compared to plastic alternatives. Verify that the 8-pin configuration fits the available board space and that bipolar power consumption is acceptable for the design.

Part Context

Harris Corporation was a prominent manufacturer of analog and mixed-signal ICs before its acquisition by Intersil, which later became part of Renesas Electronics. The CA0555 series represents legacy timer designs from this lineage, often found in industrial or aerospace applications requiring long-term availability and ruggedness.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with Intersil/Renesas datasheets for potential pin-compatible replacements such as the ICM7555 or standard NE555 variants, noting differences in voltage ranges and package types.
