ISL88716IP826Z

Supervisors Overview

The ISL88716IP826Z is a microprocessor supervisor integrated circuit manufactured by Intersil, designed for power management applications. It features a single-channel monitoring capability with a fixed voltage threshold of 2.63V. The device provides push-pull or totem pole output configurations and supports both high-active and low-active reset signals. It operates within a temperature range of -40°C to 85°C (TA) and is housed in an 8-pin PDIP package with a width of 0.300 inches (7.62mm). The component is classified as obsolete.

Supervisors Feature Summary

• Provides simple reset and power-on reset functionality for system supervision
• Features a push-pull, totem pole output structure for robust signal driving
• Includes manual reset input capability for user-initiated system control

Supervisors Applications

• Microprocessor system supervision
• Power management circuits
• Industrial controls

Supervisors Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability should focus on surplus distributors or secondary markets rather than direct manufacturing channels. Confirm the specific package variant and revision level when sourcing from non-original suppliers to ensure compatibility with existing designs.

Supervisors Selection Notes

Select this part only if legacy design compatibility is required, as it is no longer in active production. Ensure the 2.63V threshold aligns with the monitored rail voltage. Verify that the 8-PDIP package fits the target PCB footprint. Consider newer equivalents from Renesas if new designs are being developed.

Supervisors Part Context

The ISL88716 belongs to the Intersil/Renesas family of microprocessor supervisors, which also includes variants like the ISL88708 and ISL88813. These devices typically offer watchdog timers, power-fail comparators, and adjustable power-on resets. The IP suffix indicates an 8-pin DIP package, while IB denotes SOIC packaging.

Supervisors Replacement Considerations

Public confirmed substitute part numbers include ISL88708IB826Z and ISL88708IP826Z. These alternatives share similar supervisor functions but may differ in package type or specific feature sets such as watchdog timer inclusion. Verify pinout compatibility before substitution.
