Overview
The TSX339IYPT is a micropower CMOS quad voltage comparator in TSSOP-14 automotive grade packaging. It operates on a single supply from 2.7 V to 16 V or dual supplies of ±1.35 V to ±8 V, consuming 5 µA typical per comparator. Key electrical parameters include an input offset voltage of 0.1 mV typical, input bias current of 1 pA typical, and response time of 2.5 µs at 5 mV overdrive. The device features open-drain outputs with 20 mA sink capability, high input impedance of 10^12 Ω, and ESD tolerance of 4 kV HBM.
Feature Summary
- Micropower operation with extremely low input bias current
- Wide single or dual supply voltage range
- Open-drain output configuration
- High ESD protection levels
Applications
- Automotive systems
- Industrial applications
Procurement Notes
Verify the specific ordering suffix 'Y' indicates automotive-grade qualification for the TSSOP14 package as defined in official STMicroelectronics documentation. Confirm that the component meets required environmental specifications and temperature ranges before procurement. Ensure compatibility with existing design constraints regarding package dimensions and pinout configurations.
Selection Notes
Select this component when low power consumption and high input impedance are critical requirements. The open-drain output necessitates external pull-up resistors for proper logic level interfacing. Consider the wide common-mode input range including ground for versatile signal conditioning applications across varying supply voltages.
Part Context
This part belongs to the TSX339 family of micropower quad comparators. It serves as an improved version of the TS339, offering lower current consumption, better input offset voltage, and enhanced ESD tolerance. The TSX339IYPT specifically denotes the automotive-grade variant in TSSOP14 packaging, fully compatible with standard TS339 functions.
Replacement Considerations
The TSX339IYPT is pin-to-pin and functionally compatible with the standard TS339 quad CMOS comparators. Designers can substitute TS339 parts directly without circuit modifications, provided the application does not require the specific automotive-grade certification associated with the 'Y' suffix.
FAQ
What is the input common-mode voltage range?
The input common-mode voltage range includes ground, extending from 0 V to (VCC+) - 1.5 V under standard operating conditions.
How should unused channels be configured?
To avoid unexpected additional consumption, unused channels should be connected to the power supply pins to keep the circuit in a stable state.
