THS6182: BIAS-1 and BIAS-2 logic input circuit

Hello Nicky,

The "Logic Control Characteristics" section of the datasheet shows the voltage levels needed for each logic state.

Voltages between 0.8V-2V may give a different logic level than desired and like you mentioned Schmidt-triggered inputs can help fix this issue.

Best,

Hello Hasan,

I am aware of the above datasheet description, but this was not my question.
I't is not relevant for my application if applying voltages between 0.8V-2V may give a different logic level than desired.
My question was: Can the THS6182 be damaged if voltages between 0.8V-2V are applied for a long period of time?
Usually the input voltage drives 2 FETs, to GND and to VCC(3.3V or 5V rail) when the output circuit is a push-pull configuration.
In some cases an intermediate voltage can turn ON both FETs resulting in a HIGH current from the voltage rail to GND.
When the transition is fast, this state is very short or does not happen at all, but if the transition is slower, the high current can generate enough heat or damage the FET's if they're not rated for this condition or current.
I don't want to incorporate Schmidt triggers in my circuit unless it is REALLY NECESSARY !!
Space is a limiting factor in my application.
Please take my latest notes into consideration on your next reply or point me to someone who has knowledge about the internal circuit implementation of this chip.
