8 / 20 page ADM2682E/ADM2687E Preliminary Technical Data Rev. PrE | Page 8 of 20 PIN CONFIGURATION AND FUNCTION DESCRIPTIONS Figure 2. Pin Configuration Table 10. Pin Function Description Pin No. Mnemonic Description 1 GND1 Ground, Logic Side. 2 VCC Logic Side Power Supply. It is recommended that a 0.1 µF and a 0.01 µF decoupling capacitor be fitted between Pin 2 and Pin 1. 3 RxD Receiver Output Data. This output is high when (A − B) ≥ -30 mV and low when (A − B) ≤ –200 mV. The output is tristated when the receiver is disabled, that is, when RE ���isdrivenhigh. 4 RE ��� ReceiverEnableInput.Thisisanactive-lowinput.Drivingthisinputlowenablesthereceiver;drivingit high disables the receiver. 5 DE Driver Enable Input. Driving this input high enables the driver; driving it low disables the driver. 6 TxD Driver Input. Data to be transmitted by the driver is applied to this input. 7 VCC Logic Side Power Supply. It is recommended that a 0.1 µF and a 10 µF decoupling capacitor be fitted between Pin 7 and Pin 8. 8 GND1 Ground, Logic Side. 9 GND2 Ground, Bus Side. 10 VISOOUT Isolated Power Supply Output. This pin must be connected externally to VISOIN. It is recommended that a reservoir capacitor of 10 µF and a decoupling capacitor of 0.1 µF be fitted between Pin 10 and Pin 9. 11 Y Driver Noninverting Output 12 Z Driver Inverting Output 13 B Receiver Inverting Input. 14 A Receiver Noninverting Input. 15 VISOIN Isolated Power Supply Input. This pin must be connected externally to VISOOUT. It is recommended that a 0.1 µF and a 0.01 µF decoupling capacitor be fitted between Pin 15 and Pin 16. 16 GND2 Ground, Bus Side.
