TS334IPT

Overview

The TS334IPT is a quad micropower low-voltage comparator from STMicroelectronics, housed in a TSSOP-14 surface-mount package. It operates within a supply voltage range of 1.6 V to 5 V with a typical current consumption of 20 μA. The device features rail-to-rail inputs and an open-drain output capable of sourcing 22 mA per channel. Key electrical parameters include a propagation delay of 210 ns, an input offset voltage of 5 mV, and an input bias current of 40 nA. It supports a wide operating temperature range from -40 °C to +125 °C and offers ESD tolerance of 2 kV HBM.

Feature Summary

• Rail-to-rail input capability for low-voltage applications
• Open-drain output configuration with low saturation voltage
• Automotive qualified SMD packages for space-constrained designs

Applications

• Low-voltage signal conditioning circuits
• Battery-powered monitoring systems
• Industrial sensor interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the component meets the required automotive qualification standards if used in vehicle electronics. Cross-reference the RoHS compliance status with the latest environmental declaration documents provided by STMicroelectronics before finalizing procurement.

Selection Notes

Select this component when system design requires multiple comparators in a compact form factor with minimal power draw. The quad configuration reduces board space compared to single units. Verify that the open-drain output architecture aligns with the downstream logic levels and pull-up resistor requirements of the target application circuit.

Part Context

This part belongs to the TS33x family, which includes single (TS331) and dual (TS332) variants. The series is designed for cost-effective, low-power analog comparison tasks. The TS334 specifically provides four independent channels, making it suitable for complex signal processing where size and energy efficiency are critical constraints.

Replacement Considerations

Check for direct cross-references such as the TS339 series for similar quad comparator functionality. Verify pin compatibility and electrical specifications against alternative manufacturers' parts before substitution.
