MCP6567T-E/MS

Comparators Overview

The MCP6567T-E/MS is a dual-channel, low-power analog comparator from Microchip Technology. It features open-drain outputs and operates on a single supply voltage ranging from 1.8V to 5.5V. The device draws a typical quiescent current of 100 µA per comparator. Key electrical specifications include a typical propagation delay of 56 ns at 1.8V and an input offset voltage of ±3 mV. It supports rail-to-rail input operation and includes internal hysteresis to prevent output chattering.

Comparators Feature Summary

• Features open-drain digital outputs that facilitate level shifting and wired-OR logic implementation.
• Incorporates internally set hysteresis to eliminate output switching caused by input noise voltage.
• Supports rail-to-rail input operation with extended common-mode voltage range beyond supply rails.
• Optimized for low-power consumption with minimal quiescent current draw in single-supply applications.

Comparators Applications

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

Comparators Procurement Notes

Verify the specific suffix 'E' corresponds to the industrial temperature range (-40°C to +125°C) as defined in the official datasheet. Confirm the 'MS' package designation matches the required MSOP-8 footprint. Ensure the 'T' indicates tape-and-reel packaging if reel quantity is required. Cross-reference the manufacturer part number against the latest revision of DS20002143G to confirm pinout and electrical characteristics.

Comparators Selection Notes

Select this component when a dual-channel comparator with open-drain outputs is required for low-voltage systems. It is suitable for applications needing rail-to-rail input capability and internal hysteresis to reduce dynamic power consumption. Consider alternative packages like SOIC or TSSOP if MSOP-8 is unavailable, ensuring the functional family remains compatible.

Comparators Part Context

This device belongs to the MCP6566/6R/6U/7/9 family of CMOS/TTL-compatible comparators. The family offers single, dual, and quad configurations optimized for 1.8V single-supply applications. The MCP6567 specifically provides two independent channels within an 8-pin surface-mount package, distinguishing it from single-channel or quad-channel variants in the same series.

Comparators Replacement Considerations

The push-pull output variant MCP6561/1R/1U/2/4 serves as a functional substitute but requires different output stage handling. Other members of the MCP6566/6R/6U/7/9 family offer identical electrical characteristics with varying channel counts or package types.
