TS332IQ2T

Overview

The TS332IQ2T is a dual micropower low-voltage analog comparator manufactured by STMicroelectronics. It operates within a supply voltage range of 1.6 V to 5 V and consumes a typical quiescent current of 20 µA. The device features rail-to-rail inputs, an open-drain output capable of sourcing up to 22 mA per channel, and a propagation delay of 210 ns. Input offset voltage is specified at 5 mV with an input bias current of 40 nA. It is housed in an 8-DFN (2x2 mm) surface-mount package and supports operating temperatures from -40 °C to +125 °C.

Feature Summary

• Rail-to-rail input capability enables accurate signal detection across the full supply voltage range.
• Micropower architecture ensures minimal energy consumption suitable for battery-operated systems.
• Open-drain output configuration allows flexible interfacing with various logic families via external pull-up resistors.

Applications

• Portable consumer electronics requiring low power consumption
• Battery-powered monitoring circuits
• Low-voltage signal conditioning

Procurement Notes

Verify the specific ordering suffix to confirm the reel packaging quantity and tape specifications. Ensure the component matches the required automotive qualification status if applicable to the target application. Cross-reference the datasheet revision date to confirm parameter consistency during procurement.

Selection Notes

Select this component when dual-channel comparison is needed in space-constrained designs. The open-drain output requires an external pull-up resistor; ensure the selected resistor value aligns with the desired switching speed and load requirements. Verify that the 5 mV offset voltage meets the precision needs of the specific circuit application.

Part Context

This part belongs to the TS33x family of comparators, which includes single (TS331), dual (TS332), and quad (TS334) variants. All members share similar electrical characteristics, including low voltage operation and micropower consumption, allowing for design scalability based on channel count requirements.

Replacement Considerations

Direct substitutes include other dual-channel comparators from the same manufacturer series, such as the TS332I or TS332M, provided the package footprint and electrical parameters remain compatible with the existing design constraints.
