TS884IPT

Overview

The TS884IPT is a quad analog comparator manufactured by STMicroelectronics, housed in a 14-TSSOP surface-mount package. It operates on a single supply voltage ranging from 1.1 V to 5.5 V. The device features ultra-low supply current consumption of 220 nA typical per operator with output high at 1.2 V no load. Key electrical parameters include a propagation delay of 2 µs typical and a response time of 13 µs. Input characteristics specify an input offset voltage of 6 mV maximum and an input bias current of 100 pA maximum. Each channel provides a push-pull output capable of sourcing or sinking 1.7 mA. The component supports a wide operating temperature range from -40 °C to +125 °C.

Feature Summary

• Ultra-low power consumption designed to minimize battery leakage and extend operational life in portable devices.
• Rail-to-rail input capability allowing signal detection across the full supply voltage range.
• Push-pull output stage providing direct drive capability for digital logic interfaces without external pull-up resistors.

Applications

• Portable consumer electronics requiring extended battery life
• Battery-powered monitoring systems
• Low-voltage signal conditioning circuits

Procurement Notes

Verify the specific ordering suffix to confirm the TSSOP-14 package configuration. Ensure compatibility with the required moisture sensitivity level and reflow soldering profiles for surface-mount assembly. Confirm RoHS compliance status matches project requirements before finalizing procurement orders.

Selection Notes

Select this component when designing low-power systems requiring four independent comparison functions in a compact footprint. The rail-to-rail inputs accommodate signals swinging near ground or the positive supply rail. The push-pull outputs simplify interface design compared to open-collector alternatives. Verify that the 1.1 V minimum supply voltage aligns with the system's available power rails.

Part Context

This part belongs to the TS88x series of nanopower comparators from STMicroelectronics. The series includes dual (TS882) and quad (TS884) variants. These devices are engineered for applications where power efficiency is critical, such as battery-operated instruments. The TS884 specifically integrates four comparators into a single 14-pin package to save board space.

Replacement Considerations

The MCP6544-I/ST from Microchip Technology is listed as a substitute option. Verify pinout compatibility and electrical parameter alignment before substitution.
