1, 3, 7, 9, 10 GND1 Ground, Logic Side. 2 NC No Connect. Do not connect to this pin. 4 RxD Receiver Output Data. 5 TxD Driver Input Data. 6 VIO iCoupler Power Supply. It is recommended that a 0.1 μF and a 0.01 μF decoupling capacitor be fitted between Pin 6 and GND1. See Figure 28 for layout recommendations. 8 VCC isoPower Power Supply. It is recommended that a 0.1 μF and a 10 μF decoupling capacitor be fitted between Pin 8 and Pin 9. 11, 13 GND2 Ground for Isolated DC-to-DC Converter. It is recommended to connect Pin 11 and Pin 13 together through one ferrite bead to the PCB ground. 12 VISOOUT Isolated Power Supply Output. This pin must be connected external y to VISOIN. It is recommended that a ferrite bead reservoir capacitor of 10 μF and a decoupling capacitor of 0.1 μF be fitted between Pin 12 and Pin 11. 14 VREF Reference Voltage Output. It is recommended not to connect to this pin. 15 CANL Low-Level CAN Voltage Input/Output. 16, 20 GND2 Ground, Bus Side. 17 CANH High-Level CAN Voltage Input/Output. 18 RS Slope Control Pin. Short this pin to GND2 (Pin 16 or Pin 20) for full speed operation. Use a weak pull-down for slope control. An input high places the transceiver in standby. This pin must not be left floating. 19 VISOIN Isolated Power Supply Input. This pin must be connected externally to VISOOUT. It is recommended this pin have a 0.1 μF capacitor to GND2 (Pin13 or Pin 11). Connect this pin through a ferrite bead and short trace length to VISOIN for operation. Rev.
