What is the maximum working frequency of a logic driver if it was not specified in the datasheet?
Due to its characteristics, the maximum working frequency of a logic driver is dependent on many application parameters including the output trace length and the capacitive load. Normally, if the output trace length is less than 4 and the capacitive load is less than 15pf, the maximum working frequency for a logic device can go up to 150MHz-200MHz depending on the device type. But the best way to determine the maximum working frequency is to simulate the IBIS model with a particular application circuit.
