May 2017 The TSX3702 is a micropower CMOS dual voltage comparator which exhibits a very low current consumption of 5 A typical per comparator. This device was designed as the improvement of the TS3702: it shows a lower current consumption, a better input offset voltage, and an enhanced ESD tolerance. The TSX3702 is fully specified over a wide temperature range and is proposed in automotive grade for the SO8 package. It is fully compatible with the TS3702 CMOS comparator and is available with similar packages. New tiny packages (MiniSO8 and DFN8 2x2 mm) are also proposed for the TSX3702 thus allowing even more integration on applications.

When VIN > VCC+ a leakage current goes from the input through the protection diode to the ESD clamp. This current is about 0.2 nA at 25 C and about 250 nA at 125 C. For a detailed input characteristic see Figure 12.
