tsx3702 application information (input voltages) docid026056 rev 2 15 / 24 6 application information (input voltages) the esd strategy used in the tsx3702 (and shown in figure 2) allows input voltages from - 0.3 v up to 16 v to be applied regardless of the v cc + voltage. when v in > v cc + 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 . the device is designed to prevent phase reversal.
