I am using TLC339 comparator in one of our circuit with the VCC=3.3V and GND. I have attached the schematic. The input is a square wave with frequency of 100Hz and amplitude is +/- 15V.
When the input is -15V the diode will be forward bias and the input of the ic will see the -700mV whether will this create any issue for the IC? as per the datasheet the input voltage max is -300mV. But the clamp current is +/- 3mA. as per the schematic we are not crossing the 3mA current.
Please let me know if you have any concerns??
