ADM3491 Pin Configuration Table 7. Pin Function Descriptions ADM3483/ ADM3485 Pin No. ADM3488/ ADM3490 Pin No. ADM3491 Pin No. Mnemonic Description 1 2 2 RO Receiver Output. When enabled, if A > B by 200 mV, then RO = high. If A < B by 200 mV, then RO = low. 2 Not applicable 3 RE Receiver Output Enable. A low level enables the receiver output, RO. A high level places it in a high impedance state. If RE is high and DE is low, the device enters a low power shutdown mode. 3 Not applicable 4 DE Driver Output Enable. A high level enables the driver differential Output A and Output B. A low level places it in a high impedance state. If RE is high and DE is low, the device enters a low power shutdown mode. 4 3 5 DI Driver Input. With a half-duplex part when the driver is enabled, a logic low on DI forces A low and B high while a logic high on DI forces A high and B low. With a full-duplex part when the driver is enabled, a logic low on DI forces Y low and Z high while a logic high on DI forces Y high and Z low. 5 4 6, 7 GND Ground. Not applicable 5 9 Y Noninverting Driver Output. Not applicable 6 10 Z Inverting Driver Output. 6 Not applicable Not applicable A Noninverting Receiver Input A and Noninverting Driver Output A. Not applicable 8 12 A Noninverting Receiver Input A. 7 Not applicable Not applicable B Inverting Receiver Input B and Inverted Driver Output B. Not applicable 7 11 B Inverting Receiver Input B. 8 1 13, 14 VCC Power Supply (3.3 V ± 0.3 V). Not applicable Not applicable 1, 8 NC No Connect. |
