TS883IST

Overview

The TS883IST is a dual nanopower analog comparator manufactured by STMicroelectronics, housed in a MiniSO-8 surface-mount package. It operates on a supply voltage ranging from 0.9 V to 5.5 V with an ultra-low typical supply current of 250 nA per operator. The device features rail-to-rail inputs and open-drain outputs, providing a propagation delay of 2 µs typical. It supports a wide operating temperature range from -40 °C to +125 °C and includes built-in hysteresis.

Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Rail-to-rail input capability allowing full signal swing utilization
• Open-drain output configuration requiring external pull-up resistors

Applications

• Portable electronic systems
• Signal conditioning circuits
• Medical instrumentation

Procurement Notes

Verify the specific ordering code against the manufacturer's datasheet to ensure correct package type and environmental compliance grade. Confirm that the MiniSO-8 variant matches the required footprint and thermal characteristics for the target PCB design before finalizing procurement.

Selection Notes

Select this component when low quiescent current is critical for extending battery life in portable devices. The open-drain output requires careful consideration of pull-up resistor values to meet timing requirements. Ensure the application voltage remains within the 0.9 V to 5.5 V operational limits.

Part Context

This part belongs to the TS883x series of nanopower comparators, which also includes single-channel variants like the TS880. The series is designed to minimize battery leakage and enhance lifetime in portable applications through its ultra-low current consumption architecture.

Replacement Considerations

Consult the official datasheet for compatible alternatives within the same product family or cross-reference with other manufacturers offering similar nanopower dual comparators with matching pinouts and electrical specifications.
