This device was designed as the improvement of the TS339: it shows a lower current consumption, a better input offset voltage, and an enhanced ESD tolerance. The TSX339 is fully specified over a wide temperature range and is proposed in automotive grade for the TSSOP14 package. It is fully compatible with the TS339 CMOS comparator and is available with similar packages. The new tiny package, QFN16 3x3, is also proposed for the TSX339 thus allowing even more integration on applications.

If one input voltage is beyond the range 0 V to 16 V, this input of the comparator should be protected according to Figure 17. Additional, external, protection schematic. If the input is lower than Vcc-, a significant current may go through the ESD diode. To protect the circuit, this current must be limited to 10 mA by using the Rg+ or Rg- resistors. If the input is bigger than 16 V, it has to be voltage limited. This is achieved using the D- or D+ additional, external diodes. To protect these diodes, the current is limited using the Rg resistor. D- and D+ diodes can be connected to another power supply with a maximum value of 16 V. The device is designed to prevent phase reversal. Figure 17.

A simple solution is to connect the input to the power supply pins as shown in Figure 18. Input configuration for unused channel. This keeps the circuit in a stable state. Figure 18. Input configuration for unused channel Vcc+ Vcc- 6.3 Bypass capacitor To maintain proper coupling of the power supply, it is strongly recommended to place a 0.1 μF capacitor as close as possible to the supply pins.
