MCP6561T-E/OT

Comparators Overview

The MCP6561T-E/OT is a single-channel analog comparator from Microchip Technology, housed in a 5-lead SOT-23 package. It operates on a single supply voltage ranging from 1.8V to 5.5V with a typical quiescent current of 100 µA. The device features rail-to-rail input capability extending from VSS – 0.3V to VDD + 0.3V and provides a CMOS/TTL-compatible push-pull output. Key electrical specifications include a typical propagation delay of 56 ns (high-to-low) at 1.8V, an input offset voltage of ±3 mV, and an internal input hysteresis of approximately 5 mV.

Comparators Feature Summary

• Rail-to-rail input operation allows signal detection across the full supply range without phase reversal issues.
• Push-pull digital output stage supports direct interfacing with standard CMOS and TTL logic families.
• Integrated internal hysteresis prevents output chattering caused by input noise voltages.
• Optimized for low-power consumption suitable for battery-operated and portable electronic applications.

Comparators Applications

• Laptop Computers
• Mobile Phones
• Handheld Electronics
• RC Timers
• Alarm and Monitoring Circuits

Comparators Procurement Notes

Verify that the ordering suffix 'E' corresponds to the industrial temperature range (-40°C to +125°C) as specified in the datasheet. Confirm the '/OT' suffix indicates the SOT-23-5 surface-mount package configuration. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability. Cross-reference the manufacturer part number with official Microchip documentation to validate the specific revision level before integration into production designs.

Comparators Selection Notes

Select this component when a single comparator with rail-to-rail inputs and push-pull outputs is required. It is appropriate for designs needing low power consumption under 1.8V to 5.5V supplies. Consider alternative packages like SC70 or MSOP if board space constraints differ. Verify that the required propagation delay and input offset voltage meet the specific circuit performance criteria defined in the application design.

Comparators Part Context

This device belongs to the MCP6561/1R/1U/2/4 family of comparators, which includes single, dual, and quad configurations. The family shares common electrical characteristics and pinouts where applicable, allowing for scalable design implementations. Related devices within the same ecosystem include open-drain output variants such as the MCP6566 and MCP6567 series, offering flexibility for different logic interface requirements.

Comparators Replacement Considerations

Direct functional substitutes within the same package and specification profile are not explicitly listed in the provided documentation. Designers should consult the Microchip Advanced Part Selector (MAPS) tool for verified cross-references. Ensure any replacement maintains the SOT-23-5 footprint and meets the 1.8V to 5.5V operating voltage range.
