Overview
The TSX3704IYPT is a micropower CMOS quad voltage comparator in a TSSOP-14 package, designated for automotive grade applications. It operates on a single supply from 2.7 V to 16 V or dual supplies of ±1.35 V to ±8 V. Key electrical parameters include a typical supply current of 5 µA per comparator, an input offset voltage of 0.1 mV (max 5 mV), and an extremely low input bias current of 1 pA typ. The device features push-pull outputs capable of sourcing or sinking up to 20 mA, with a typical response time of 2.4 µs at 5 mV overdrive. It supports an operating temperature range of -40 °C to +125 °C.
Feature Summary
- Automotive-grade qualification compliant with AEC-Q100 standards
- Micropower consumption with 5 µA typical current draw per channel
- High ESD tolerance rated at 4 kV HBM and 200 V MM
- Push-pull output stage providing robust drive capability
Applications
- Automotive electronic systems
- Industrial control circuits
- Signal conditioning interfaces
Procurement Notes
Verify the specific ordering code TSX3704IYPT against official STMicroelectronics documentation to confirm automotive grade status and TSSOP-14 packaging. Ensure compatibility with AEC-Q100 requirements if applicable to your design. Confirm that the 'I' suffix indicates the industrial temperature range extension within the automotive specification context as defined in the datasheet.
Selection Notes
Select this component when designing for automotive environments requiring high reliability and low power consumption. The quad configuration allows multiple comparison functions in a single package. Consider the push-pull output for direct interfacing with digital logic without external pull-up resistors. Evaluate the wide common-mode input range including ground for versatile signal monitoring applications.
Part Context
The TSX3704 series represents an improvement over the legacy TS3704, offering lower current consumption, better input offset voltage, and enhanced ESD tolerance. The TSX3704IYPT specifically denotes the automotive-grade version packaged in TSSOP-14. It is fully compatible with the standard TS3704 functionally but meets stricter automotive qualification criteria.
Replacement Considerations
The TSX3704IDT serves as a pin-to-pin and functionally compatible alternative in the SO14 package. For non-automotive applications, the standard TSX3704 variants are suitable replacements. Verify that any substitute maintains the required automotive qualification if the application demands it.
FAQ
Is the TSX3704IYPT qualified for automotive use?
Yes, the TSX3704IYPT is proposed in automotive grade and is qualified according to AEC-Q100 standards.
What is the maximum differential input voltage?
The absolute maximum differential input voltage is ±18 V.
Can one input voltage exceed the supply voltage?
Yes, the output state is guaranteed as long as one input remains within the common mode range and the other input remains between -0.3 V and 16 V.
