TS884IQ4T

Overview

The TS884IQ4T is a quad analog comparator manufactured by STMicroelectronics, housed in a QFN-16 surface-mount package. It operates on a single supply voltage ranging from 1.1 V to 5.5 V with a typical quiescent current of 220 nA per operator. The device features rail-to-rail input and push-pull output capabilities, ensuring compatibility with various logic families. Key electrical parameters include a maximum input offset voltage of 6 mV, an input bias current of 100 pA, and a propagation delay of 2 µs. It supports an output current of 1.7 mA per channel and functions within a temperature range of -40 °C to +125 °C.

Feature Summary

• Ultra-low power consumption designed to minimize battery leakage in portable applications
• Rail-to-rail input capability allowing operation near supply rails
• Push-pull output structure providing direct interface to digital logic without external pull-up resistors

Applications

• Portable battery-powered equipment requiring extended operational life
• Threshold detection circuits in low-voltage systems
• Signal conditioning for microcontroller input interfaces

Procurement Notes

Verify the specific suffix IQ4T corresponds to the QFN-16 package and reel packaging configuration when ordering. Confirm that the required operating temperature range extends to +125 °C matches the industrial specification. Ensure design compatibility with the 1.1 V minimum supply voltage constraint. Validate pinout alignment with the QFN-16 footprint during PCB layout. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when ultra-low static current is critical for battery longevity in portable devices. The rail-to-rail inputs allow signal processing close to ground and supply limits. Push-pull outputs simplify circuit design by eliminating the need for external pull-up components. Consider the 2 µs propagation delay for timing-sensitive applications. Evaluate the QFN-16 package size against available board space constraints.
