IL4622E / IL4685E IL4622E Pin Connections
1 VDD1B Transceiver controller-side power supply input (3.3 V nominal). 2 GND1 Input power supply ground (pin 2 is internally connected to pin 8). 3 R Output data from bus. Read data enable. If RE is high, R = high impedance; has a 500 kΩ 4 RE nominal internal pulldown. 1 16 V V DD1B DD2 5 DE Drive enable (has a 1 MΩ nominal internal pulldown). 2 15 GND 6 D Data input to bus. GND 1 2 7 VDD1A DC-DC convertor input voltage (3.3 V nominal); bypass with 0.1 µF. 3 14 R B 8 GND1 Input power supply ground (pin 8 is internally connected to pin 2). 4 13 RE Z 9 GND2 Output power supply ground (pin 9 is internally connected to pin 15). Output-side rectifier output / regulator input; connect to a 0.1 µF/16 V 5 12 DE A 10 VF external filter capacitor. 6 11 D Y 11 Y Non-inverting bus driver. 12 A Non-inverting bus receiver. V 7 10 DD1A VF 13 Z Inverting bus driver. 8 9 GND GND 1 2 14 B Inverting bus receiver. 15 GND 2 Output power supply ground (pin 15 is internally connected to pin 9). DC-DC convertor output (3.3 V typical); internally powers transceiver 16 VDD2 functions. Bypass with 10 µF ceramic.
