TSX3704IQ4T

Overview

The TSX3704IQ4T is a micropower CMOS quad voltage comparator in a QFN16 3x3 package. It operates on a single supply from 2.7 V to 16 V or dual supplies of ±1.35 V to ±8 V. Typical supply current is 5 µA per comparator, with input bias current at 1 pA and offset voltage at 0.1 mV. Response time is 2.4 µs for 5 mV overdrive. The device features push-pull outputs, high input impedance of 10^12 Ω, and ESD tolerance of 4 kV HBM. Operating temperature range spans -40 °C to +125 °C.

Feature Summary

• Micropower operation with extremely low typical supply current of 5 µA per comparator
• Push-pull output stage providing high input impedance and wide common-mode voltage range including ground
• Enhanced robustness with 4 kV HBM ESD tolerance and latch-up immunity up to 200 mA

Applications

• Automotive systems
• Industrial applications

Procurement Notes

Verify the specific QFN16 3x3 package configuration matches the design requirements. Confirm that the operating conditions align with the specified electrical characteristics across the full temperature range. Ensure proper bypass capacitor placement near supply pins as recommended in application information.

Selection Notes

Select this component when low power consumption and high precision are required in space-constrained designs. The QFN16 3x3 package offers compact integration compared to SO14 or TSSOP14 options. Consider the push-pull output capability if rail-to-rail drive is needed without additional external components.

Part Context

The TSX3704 series improves upon the TS3704 by offering lower current consumption, better input offset voltage, and enhanced ESD tolerance. It is fully compatible with the TS3704 CMOS comparator family. The TSX3704IYPT variant is proposed in automotive grade for the TSSOP14 package.

Replacement Considerations

Pin-to-pin and functionally compatible with the dual CMOS TS3704 comparators. For open drain output requirements, consider the TSX339.
