Overview
The UPC277GR(20)-9LG-E2-A is a dual-channel analog comparator from the Renesas UPC277G2 series, housed in an 8-TSSOP surface-mount package. It operates on a supply voltage range of 2V to 32V (single) or ±1V to ±16V (dual). Key electrical parameters include a maximum input offset voltage of 5mV at 5V, a typical output current of 16mA at 5V, and a maximum quiescent current of 800µA. The device features open-collector outputs and supports a wide operating temperature range from -40°C to +125°C.
Feature Summary
- Dual-channel configuration for general-purpose signal comparison tasks
- Open-collector output structure providing flexible interfacing capabilities
- Wide single-supply voltage operation supporting diverse power environments
Applications
- General-purpose voltage threshold detection circuits
- Signal conditioning within industrial control systems
- Over-voltage or under-voltage protection monitoring
Procurement Notes
Verify the specific suffix E2 against the required RoHS compliance standards for your region. Confirm the 8-TSSOP package dimensions match your PCB footprint requirements. Ensure the open-collector output type aligns with your downstream logic interface needs. Check for any recent Product Change Notices regarding labeling or manufacturing site updates before finalizing orders.
Selection Notes
Select this component when a dual-channel solution is required with low offset voltage precision. The wide supply voltage range makes it suitable for both low-power and high-voltage applications. Consider the open-collector output requirement for pull-up resistor integration. Verify that the thermal performance meets the system's ambient temperature constraints within the specified industrial range.
Part Context
This part belongs to the UPC277G2 series of analog comparators manufactured by Renesas Electronics. It is designed as a cost-effective alternative to older discrete comparator solutions, offering integrated dual channels in a compact surface-mount package. The series is widely used in consumer electronics and industrial equipment requiring reliable signal switching.
Replacement Considerations
The UPC277GR(20)-9LG-E1-A is documented as a parameter-equivalent substitute. Verify pin compatibility and electrical specifications before swapping. No other cross-manufacturer replacements are confirmed in available public data.
