Overview
The TS391IQ2T is a low-power, single voltage comparator manufactured by STMicroelectronics. It operates from a single supply ranging from 2 V to 36 V or dual supplies of ±1 V to ±18 V. The device features very low supply current of 0.2 mA independent of supply voltage and low input bias current of 25 nA typical. It offers an input common-mode voltage range that includes ground, even with single supply operation. The output is compatible with TTL, DTL, ECL, and CMOS logic families.
Feature Summary
- Designed for low-power applications with supply current independent of voltage
- Input common-mode voltage range extends to ground on single supply
- Output compatibility with standard digital logic families including TTL and CMOS
Applications
- General-purpose voltage comparison in single-supply systems
- Signal conditioning circuits requiring ground-referenced inputs
- Battery-powered devices due to low power consumption
Procurement Notes
Verify the specific suffix IQ2T against official STMicroelectronics documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor listings to confirm authenticity and availability status before procurement.
Selection Notes
Select this component when a single-supply comparator with ground-referenced input capability is required. Consider the 2 V minimum supply voltage constraint for low-voltage designs. Evaluate the open-collector output drive capability against load requirements. Compare performance metrics such as offset voltage and propagation delay against alternative comparators if higher precision or speed is needed.
Part Context
The TS391IQ2T belongs to the TS391 series of low-power voltage comparators. This series is characterized by its ability to operate over a wide voltage range while maintaining low power consumption. The IQ2T designation typically indicates a specific surface-mount package configuration and packaging format suitable for automated assembly processes.
