Overview
The TS391RILT is a single-channel low-power voltage comparator manufactured by STMicroelectronics, designed for operation from a single supply over a wide voltage range of 2 V to 36 V. It features a maximum input offset voltage of 5 mV at 30 V and a typical output current of 16 mA at 5 V. The device supports CMOS, DTL, ECL, MOS, and TTL compatible outputs. It operates within an extended temperature range of -40°C to 125°C and is qualified to AEC-Q100 automotive standards. The component is housed in a SOT-23-5 surface-mount package.
Feature Summary
- Operates from a single supply voltage ranging from 2 V to 36 V or dual supplies up to ±18 V
- Input common-mode voltage range includes ground even with single supply operation
- Outputs are compatible with various logic families including CMOS, DTL, ECL, and TTL
- Qualified for automotive applications under the AEC-Q100 standard
Applications
- Signal conditioning circuits requiring low power consumption
- Threshold detection systems utilizing single-supply operation
- Automotive electronic control units requiring AEC-Q100 compliance
Procurement Notes
Verify the specific suffix RILT corresponds to the reel packaging format required for your assembly line. Confirm that the AEC-Q100 qualification meets the specific reliability class requirements of your target application. Ensure the SOT-23-5 footprint matches your PCB design guidelines before finalizing procurement orders.
Selection Notes
Select this component when a low-power comparator with rail-to-rail input capability relative to ground is needed. It is suitable for designs where the input signal swings near the negative supply rail. Consider the 16 mA output drive capability for direct interfacing with digital logic without additional buffering stages.
Part Context
This part belongs to the TS391 series of low-power comparators. The series is characterized by its ability to function efficiently across a wide voltage spectrum while maintaining low static current consumption. It serves as a general-purpose solution for analog signal comparison tasks in both industrial and automotive environments.
Replacement Considerations
Check for other variants within the TS391 family that may offer different offset voltage grades or packaging options. Verify pinout compatibility if substituting with comparable comparators from other manufacturers to ensure direct replacement functionality.
