Overview
The TS861ILT is a single rail-to-rail micropower BiCMOS comparator manufactured by STMicroelectronics. It operates within a supply voltage range of 2.7 V to 10 V and supports an operating temperature range from -40 °C to +85 °C. The device features ultra-low current consumption of 6 µA per comparator at 2.7 V, with a maximum input offset voltage of 10 mV and a typical response time of 2 ns. It utilizes a push-pull output stage and is housed in a SOT-23-5 micro package.
Feature Summary
- Rail-to-rail CMOS inputs enable full signal swing capability across the supply range.
- Push-pull output structure allows direct connection to digital logic without external pull-up resistors.
- Ultra-low power consumption ensures extended battery life in portable applications.
- Integrated ESD protection and latch-up immunity enhance system reliability.
Applications
- Battery-powered systems requiring low quiescent current
- Threshold detection circuits
- Voltage monitoring applications
Procurement Notes
Verify the specific suffix 'I' indicates the tape and reel packaging format when ordering. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the selected variant matches the required temperature grade and package type for your PCB layout constraints.
Selection Notes
Select this component for designs prioritizing minimal power usage alongside fast response times. The rail-to-rail input capability simplifies interface design with various sensor types. Consider the SOT-23-5 package size for space-constrained layouts compared to larger SO-8 alternatives.
Part Context
This part belongs to the TS86x family of rail-to-rail micropower comparators, which includes dual (TS862) and quad (TS864) variants. The family shares identical electrical characteristics and pinout compatibility where applicable, allowing for scalable design solutions using the same core technology across different channel counts.
Replacement Considerations
Direct functional substitutes within the same family include the TS862 and TS864 for multi-channel requirements. Verify pinout compatibility if replacing with other single-channel comparators, as package variations may exist.
