Hello Team,
I would like to make sure the LM393 absolute MAX input voltage range.
Our LM393-N data sheet describes as below.
"The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is V+−1.5 V at 25°C, but either or both inputs can go to 36 V without damage, independent of the magnitude of V+."
LM393 (None "N" version)
"The voltage at either input should not be allowed to go negative by more than 0.3 V otherwise output may be incorrect and excessive input current can flow. The upper end of the common-mode voltage range is limited by VCC – 2V. However only one input needs to be in the valid common mode range, the other input can go up the maximum VCC level and the comparator provides a proper output state. Either or both inputs can go to maximum VCC level without damage."
Can both devices accept input voltage goes up to 36V regardless of Vcc voltage ?
Best Regards,
Jin
