ICL7665SACJA

Supervisors Overview

The ICL7665SACJA is a CMOS voltage detector manufactured by Harris Corporation, housed in an 8-pin ceramic dual in-line package (CERDIP). It operates with a nominal supply voltage of 5 V and draws a maximum supply current of 0.01 mA. The device functions within a commercial temperature range of -40 °C to +70 °C. It features through-hole terminals with a pitch of 2.54 mm and utilizes a tin/lead (Sn/Pb) surface finish.

Supervisors Feature Summary

• Provides dual-channel voltage supervision for system monitoring
• Utilizes open-drain or open-collector output configuration
• Constructed using CMOS technology for low power consumption

Supervisors Applications

• Embedded system power management
• Microcontroller reset circuitry
• Battery-powered device supervision

Supervisors Procurement Notes

Verify component authenticity due to potential availability from legacy stock or third-party distributors. Confirm the specific manufacturer origin, as Harris Corporation assets were acquired by Renesas Electronics. Ensure the ceramic DIP package matches the design requirements, as plastic variants exist within the same family. Check RoHS compliance status, as older Harris batches may not meet current environmental regulations.

Supervisors Selection Notes

Select this component when a robust ceramic package is required for high-reliability applications. The dual-channel capability allows monitoring of multiple voltage rails simultaneously. Consider the open-drain output compatibility with the target logic levels. Verify that the 5 V nominal supply aligns with the system's primary power rail before integration into the design.

Supervisors Part Context

This part belongs to the ICL7665 series of supervisory circuits originally developed by Harris Semiconductor. The series includes various packages and threshold options. The 'JA' suffix typically denotes the ceramic DIP package variant. This component represents legacy industrial-grade electronics now managed under broader semiconductor portfolios following corporate acquisitions.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include ICL7665SACBAZ and ICL7665SCBAZA from Renesas Electronics Corporation.
