HA1631D03TEL-E

Overview

The HA1631D03TEL-E is a single analog comparator manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 1.8V to 5.5V and features an input offset voltage maximum of 5mV. The device provides both open-drain and push-pull output configurations, with a typical static current consumption of 10µA and a typical output current of 14mA. Common-mode rejection ratio and power supply rejection ratio are typically rated at 80dB. It functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Dual-output configuration offering both open-drain and push-pull options for flexible interfacing.

Applications

• General-purpose signal comparison in electronic circuits

Procurement Notes

This component is classified as obsolete and has been discontinued by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or approved replacement parts. Ensure compliance with end-of-life notifications and confirm that any substitute components meet the original electrical specifications and package requirements before integration into designs.

Selection Notes

Select this part only if legacy compatibility is required, as it is no longer in production. Evaluate alternative comparators from the same family or competitors that offer active status. Verify that the SC-70-5 package and low-voltage operation align with the system constraints. Confirm that the dual-output capability meets the interface needs without requiring additional logic inversion.

Part Context

The HA1631 series consists of low-power, single-supply analog comparators designed for general-purpose applications. These devices are characterized by low input bias current and wide common-mode input voltage ranges. The D03 variant specifically denotes the pinout and internal configuration within the HA1631S family, intended for compact surface-mount implementations.

Replacement Considerations

Verify cross-references with other single-channel comparators featuring similar supply voltage ranges and output types. Check datasheets for matching input offset voltage and propagation delay characteristics to ensure functional equivalence in existing designs.
