2 / 11 page 2 Truth Table TRANSMITTING INPUTS OUTPUTS RE DE DI B/Z A/Y X 1101 X 1010 X 0 X High-Z High-Z Truth Table RECEIVING INPUTS OUTPUT RE DE A-B RO 00 ≥ +0.2V 1 00 ≤ -0.2V 0 0 0 Inputs Open 1 1 X X High-Z Pin Descriptions PIN FUNCTION RO Receiver output: If A > B by at least 0.2V, RO is high; If A < B by 0.2V or more, RO is low; RO = High if A and B are unconnected (floating). 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 RS-485/422 level, noninverting receiver input and noninverting driver output. Pin is an input (A) if DE = 0; pin is an output (Y) if DE = 1. B/Z RS-485/422 level, inverting receiver input and inverting driver output. Pin is an input (B) if DE = 0; pin is an output (Z) if DE = 1. VCC System power supply input (4.5V to 5.5V).
