Pin Descriptions PIN FUNCTION RO Receiver output: If A-B ≥ -50mV, RO is high; If A-B ≤ -200mV, RO is low; RO = High if A and B are unconnected (floating) or shorted. RE Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE is high. DE Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high. They are high impedance when DE is low. DI 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 Ground connection. A/Y ±15kV HBM ESD Protected RS-485/422 level, noninverting receiver input and noninverting driver output. Pin is an input if DE = 0; pin is an output if DE = 1. B/Z ±15kV HBM ESD Protected RS-485/422 level, Inverting receiver input and inverting driver output. Pin is an input if DE = 0; pin is an output if DE = 1. A ±15kV HBM ESD Protected RS-485/422 level, noninverting receiver input. B ±15kV HBM ESD Protected RS-485/422 level, inverting receiver input. Y ±15kV HBM ESD Protected RS-485/422 level, noninverting driver output. Z ±15kV HBM ESD Protected RS-485/422 level, inverting driver output. VCC System power supply input (4.5V to 5.5V). NC No Connection. ISL83080E, ISL83082E, ISL83083E, ISL83085E, ISL83086E, ISL83088E |
