Type Description
Input
Driver input. A low on DI forces the Y output low and the Z output high.
A high on DI forces the Y output high and the Z output low.
Supply
Input
Power supply (V_CC = 3.3V ± 5%). Bypass with 0.1µF capacitor to ground.
Driver output enable. A high on DE enables the driver outputs (Y and
Z). A low on DE will disable the driver outputs (Y and Z), tri-stating the
outputs and putting the device into shutdown (low power) state.
The hot swap function is implemented on the DE pin, see Applications
Information section for a description of hot swap function.
Bus Output ±15kV ESD protected, RS-485/RS-422 inverting driver output.
Supply Ground.
Supply ±15kV ESD protected, RS-485/RS-422 non-inverting driver output.
