Overview
The HA1631D02TEL-E is a dual CMOS analog comparator manufactured by Renesas Electronics. It features push-pull full-swing outputs designed for direct connection to logic devices and operates from a single power supply with a voltage range of 1.8 V to 5.5 V. The device draws a typical supply current of 50 µA per comparator. It is housed in an 8-pin TSSOP package and supports an operating temperature range from -40 °C to +85 °C.
Feature Summary
- Dual CMOS architecture with low voltage operation capability
- Push-pull full-swing output stage for direct logic interfacing
- Low supply current consumption optimized for battery applications
Applications
- Battery-powered portable electronics
- Single-supply logic interface circuits
- Low voltage signal detection systems
Procurement Notes
Verify component authenticity through authorized channels as the part is marked End-of-Life. Confirm RoHS compliance status via official documentation before integration. Check moisture sensitivity handling requirements during storage and assembly processes to ensure reliability.
Selection Notes
Select this component when dual comparators are required within a compact TSSOP-8 footprint. Ensure the design utilizes a single power supply within the 1.8 V to 5.5 V range. Verify that the 50 µA quiescent current meets system power constraints and that push-pull outputs align with downstream logic input requirements.
Part Context
This device belongs to the HA1631D01/02/03/04 series of low-power dual CMOS comparators. The '02' designation specifically indicates the version with push-pull outputs, distinguishing it from open-drain variants like the HA1631D03/04. It is part of Renesas's broader portfolio of analog mixed-signal integrated circuits.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. As the product is discontinued, engineers must evaluate alternative dual comparators with compatible pinouts, supply voltage ranges, and output configurations.
