- Battery-powered devices
Procurement Notes
Verify the specific package type and tape-and-reel specifications against the official datasheet before ordering. Confirm that the operating temperature range meets your system requirements. Ensure compatibility with your supply voltage levels. Check for any automotive qualification markings if required for your application. Validate pinout assignments for your PCB layout.
Selection Notes
Select this component when low power consumption and rail-to-rail input performance are critical. Consider the open-drain output requirement for interface compatibility. Evaluate the propagation delay against your signal speed needs. Verify that the supply voltage range aligns with your system's power rails. Assess the package size constraints for your design.
Part Context
The TS331 is part of the TS33x family, which includes dual (TS332) and quad (TS334) variants. This family shares similar electrical characteristics and is designed for space-constrained, low-voltage applications. The components are automotive qualified and offer wide temperature operation. They are commonly used in portable electronics and industrial control systems where power efficiency is paramount.
Replacement Considerations
Check for direct pin-compatible substitutes within the TS33x family or other ST comparers with similar specs. Verify equivalent electrical parameters such as supply voltage range, current consumption, and propagation delay. Ensure the replacement supports rail-to-rail inputs and open-drain outputs if required.
