MCP6574T-E/ST

Comparators Overview

The MCP6574T-E/ST is a quad analog comparator manufactured by Microchip Technology, housed in a 14-pin TSSOP surface-mount package. It operates on a single supply voltage ranging from 2.0 V to 5.5 V with a typical quiescent current of 100 µA per channel. The device features rail-to-rail inputs and push-pull outputs, supporting an input bias current of 350 pA and an input offset voltage of 1.5 mV. It provides a gain-bandwidth product of 2 MHz and a slew rate of 1.1 V/µs, ensuring fast response times suitable for precision applications across an industrial temperature range of -40°C to +125°C.

Comparators Feature Summary

• Quad configuration with rail-to-rail input capability
• Push-pull output stage for direct logic interfacing
• Low power consumption with 100 µA quiescent current per channel
• Automotive grade qualification (AEC-Q100)

Comparators Applications

• Battery management systems
• Temperature monitoring circuits
• Industrial process control
• Automotive sensor interfaces

Comparators Procurement Notes

Verify the specific suffix 'ST' corresponds to the TSSOP-14 package variant when sourcing. Confirm AEC-Q100 automotive qualification requirements align with target application standards. Check for moisture sensitivity levels and reflow soldering profile constraints during assembly planning. Ensure supply chain stability for the E-temp industrial grade designation.

Comparators Selection Notes

Select this component when a quad comparator with high speed and low power is required. The rail-to-rail input allows operation near supply rails, while push-pull outputs simplify interface design compared to open-drain alternatives. Consider the 1.5 mV offset voltage for precision threshold detection needs. The TSSOP-14 package offers a compact footprint for space-constrained PCB layouts.

Comparators Part Context

This part belongs to the MCP64xx series of operational amplifiers and comparators from Microchip. It shares architectural similarities with other quad devices in the family but is optimized for comparator-like performance characteristics including higher slew rates and specific offset voltage specifications tailored for signal conditioning tasks.

Comparators Replacement Considerations

Direct pin-compatible substitutes within the same Microchip portfolio should be verified against electrical parameter tolerances. Cross-reference with MCP6474 variants for identical functionality if packaging or thermal requirements differ.
