Overview
The TSX3704IPT is a micropower quad CMOS voltage comparator manufactured by STMicroelectronics, housed in a TSSOP-14 surface-mount package. It operates on a single supply voltage ranging from 2.7 V to 16 V or dual supplies of ±1.35 V to ±8 V. The device features four independent channels with push-pull outputs capable of sourcing and sinking up to 20 mA. Typical electrical characteristics include a supply current of 5 µA per comparator, an input offset voltage of 0.1 mV, and an input bias current of 1 pA. The response time is typically 2.7 µs for a 5 mV overdrive. It supports an operating temperature range from -40 °C to +125 °C.
Feature Summary
- Micropower consumption with typical supply current of 5 µA per comparator
- Push-pull output stage providing high drive capability
- Input common-mode voltage range includes ground potential
- High ESD tolerance rated at 4 kV HBM and 200 V MM
Applications
- Automotive systems
- Industrial control applications
Procurement Notes
Verify the specific ordering code suffix against official documentation to confirm package type and temperature grade. Confirm that the TSSOP-14 variant matches the required footprint and pinout for the target PCB design. Ensure compliance with relevant automotive qualification standards if deploying in vehicle environments.
Selection Notes
Select this component when low quiescent current and wide supply voltage operation are required. The TSSOP-14 package offers a compact solution for space-constrained designs. Consider the TSX3704IDT for SO14 packaging or TSX3704IQ4T for QFN16 integration needs.
Part Context
The TSX3704 series represents an improved version of the legacy TS3704 comparator family. It provides lower current consumption, better input offset voltage performance, and enhanced ESD tolerance. The product line includes multiple package options such as SO14, TSSOP14, and QFN16 to support various integration requirements.
Replacement Considerations
The TSX3704 is fully compatible with the TS3704 CMOS comparator. Designers replacing older TS3704 units can utilize the TSX3704 without circuit modifications due to functional equivalence.
