ADuM5401 Pin Configuration Table 11. ADuM5401 Pin Function Descriptions Pin No. Mnemonic Description 1 VDD1 Primary Supply Voltage, 3.0 V to 5.5 V. 2, 8 GND1 Ground 1. Ground reference for isolator primary. Pin 2 and Pin 8 are internally connected, and it is recommended that both pins be connected to a common ground. 3 VIA Logic Input A. 4 VIB Logic Input B. 5 VIC Logic Input C. 6 VOD Logic Output D. 7 NC Make no connection to this pin. 9, 15 GNDISO Ground Reference for Isolator Side 2. Pin 9 and Pin 15 are internally connected, and it is recommended that both pins be connected to a common ground. 10 VSEL Output Voltage Selection. When VSEL = VISO, the VISO setpoint is 5.0 V. When VSEL = GNDISO, the VISO setpoint is 3.3 V. VDD1 and VISO voltages must be in the same operating range to guarantee proper operation of the data channels. 11 VID Logic Input D. 12 VOC Logic Output C. 13 VOB Logic Output B. 14 VOA Logic Output A. 16 VISO Secondary Supply Voltage Output for External Loads, 3.3 V (VSEL Low) or 5.0 V (VSEL High). VDD1 and VISO voltages must be in the same operating range to guarantee proper operation of the data channels. |
