TH3044
K-Bus Interface
All voltages are referenced to ground (GND). Positive currents flow into the IC. The absolute maximum ratings (in accordance with IEC 134) given in the table below are limiting values that do not lead to a permanent damage of the device but exceeding any of these limits may do
so. Long term exposure to limiting values may affect the reliability of the device. Reliable operation of the TH3044 is only specified within the limits shown in ”Operating conditions”
