- Wide 1.8 V to 16 V single-supply or ±8 V dual-supply operation suits diverse power rails
- Open-drain output with 0 V to 16 V swing allows flexible logic-level interfacing and wire-OR configurations
Applications
The TSX339IPT excels in portable and battery-operated equipment where its 5 µA micropower consumption extends runtime significantly. Its 4 independent comparators in the TSSOP-14 package are ideal for threshold detection, voltage monitoring, and analog signal conditioning in IoT sensors and wearables. The open-drain output structure makes it well-suited for multi-channel alarm circuits and level-shifting interfaces.

Frequently Asked Questions
How does the TSX339IPT achieve such low power consumption, and what supply voltage range does it support?
The TSX339IPT uses micropower CMOS technology to achieve only 5 µA total supply current per comparator. It operates from a single supply of 1.8 V to 16 V or dual supplies of ±8 V, making it ideal for battery-operated systems that demand minimal quiescent current while supporting a broad input common-mode range.
What output configuration does the TSX339IPT use, and how does this affect pull-up resistor selection?
The TSX339IPT features open-drain outputs capable of sinking current while swinging from 0 V to 16 V when an external pull-up resistor is connected. A typical pull-up of 10 kΩ to 100 kΩ works well for low-speed applications, while 1 kΩ to 4.7 kΩ supports faster response times in level-shifting or wire-OR bus configurations.
How many comparators are integrated in the TSX339IPT, and which package does it come in for high-density PCB layouts?
The TSX339IPT integrates 4 independent comparator channels in a compact TSSOP-14 package, offering a 0.635 mm pitch that saves significant board space compared to separate single or dual comparator ICs. This makes it an efficient solution when 4 threshold detection or signal comparison circuits are needed within a limited PCB footprint of approximately 5 mm × 4.4 mm.
When is TSX339IPT a better choice than the LM339 for low-power handheld devices?
The TSX339IPT consumes roughly 10× less quiescent current than the LM339 (5 µA vs. 50 µA typical per comparator), which directly extends battery life in handheld and coin-cell-powered devices. It also operates from supplies as low as 1.8 V, whereas the standard LM339 requires at least 2.0 V, giving the TSX339IPT a meaningful advantage in modern 3.3 V and sub-2 V IoT designs.
