CA0555EX

Overview

The CA0555EX is a bipolar timer integrated circuit manufactured by Harris Corporation. It operates within a supply voltage range of 4.5V to 18V and supports a continuous current of 10mA. The device is designed for robust performance across an extended temperature range, functioning reliably from -55°C to 125°C.

Feature Summary

• Bipolar timer technology
• Extended military-grade temperature capability

Applications

• Military timing circuits
• Industrial control systems
• Harsh environment applications

Procurement Notes

Verify the manufacturer origin carefully, as Harris Corporation's semiconductor assets were acquired by Intersil, which was subsequently acquired by Renesas Electronics. Ensure the specific part number CA0555EX corresponds to the intended vintage or current production status, as availability may be limited to surplus or obsolete channels.

Selection Notes

Select this component when bipolar timer functionality is required in extreme thermal conditions. Confirm that the 10mA output current meets the load requirements. Verify package compatibility, as historical data indicates metal can packaging options for this series.

Part Context

Harris Corporation produced high-reliability semiconductors before its acquisition. This timer belongs to a family of analog mixed-signal ICs known for durability. The CA0555EX variant specifically addresses needs for wide operating temperatures typical in defense and aerospace sectors.

Replacement Considerations

Check for equivalents from Intersil or Renesas if available. Cross-reference with standard 555 timer variants only if voltage and temperature ratings are compatible.
