... ST2129 3 Supplementary notes 3.1 Driver requirement For proper operation, the driver from each side of the device must have the capability to source and sink a minimum of 1mA current. The device architecture requires the driver to source/sink a maximum current of (V 3.2 Load driving capability To support the architecture that allows level translation without direction pin, the one-shot transistor is turned on only during state transition at the output side. After the one-shot transistor is turned off, only the 4 kΩ ...
