Pin Descriptions PIN NAME 8 LD PIN # 10 LD PIN # 14 LD PIN # FUNCTION RO 1 1 2 Receiver output. If A-B ≥ -10mV, RO is high; if A-B ≤ -200mV, RO is low; RO = High if A and B are unconnected (floating), shorted together, or connected to an undriven, terminated bus. RE 2 2 3 Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE is high. Internally pulled low. DE 3 3 4 Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high. They are high impedance when DE is low. Internally pulled high. DI 4 4 5 Driver input. A low on DI forces output Y low and output Z high. Similarly, a high on DI forces output Y high and output Z low. GND 5 5 6, 7 Ground connection. A/Y 6 - - ±60V Fault and ±16.5kV HBM ESD Protected RS-485/RS-422 level, non-inverting receiver input and non-inverting driver output. Pin is an input if DE = 0; pin is an output if DE = 1. B/Z 7 - - ±60V Fault and ±16.5kV HBM ESD Protected RS-485/RS-422 level, inverting receiver input and inverting driver output. Pin is an input if DE = 0; pin is an output if DE = 1. A - 9 12 ±60V Fault and ±15kV HBM ESD Protected RS-485/RS-422 level, non-inverting receiver input. B - 8 11 ±60V Fault and ±15kV HBM ESD Protected RS-485/RS-422 level, inverting receiver input. |
