Other Parts Discussed in Thread: THVD2450
the SN65HVD78 and similar parts like (THVD2450) have the following structure on the Receive pin (datasheet page 16)
I would like to know the impedance of the output stage ? or how to calculate it from rise time and fall time.
I would also like to know the capacitance of the Input pin "D" or how to calculate from the datasheet parameters.
The reason I need this information is that i want to place a series resistor on this "R" pin to match it to the pcb track impedance simlar to the following figure:
