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 3 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 4 5 6, 7 Ground connection. This is also the potential of the TDFN EPAD. A/Y 6 - - - ±60V Fault 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 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 - 8 9 12 ±60V Fault Protected RS-485/RS-422 level, non-inverting receiver input. B - 7 8 11 ±60V Fault Protected RS-485/RS-422 level, inverting receiver input. Y - 5 6 9 ±60V Fault Protected RS-485/RS-422 level, non-inverting driver output. Z - 6 7 10 ±60V Fault Protected RS-485/RS-422 level, inverting driver output. VCC 8 1 10 13, 14 System power supply input (4.5V to 5.5V). PD - - TDFN ONLY - TDFN exposed thermal pad (EPAD). Connect to GND. NC - - - 1, 8 No Internal Connection. |
