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
±16.5kV IEC61000 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
±16.5kV IEC61000 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
±16.5kV IEC61000 ESD Protected RS-485/RS-422 level, non-inverting receiver input.
B
±16.5kV IEC61000 ESD Protected RS-485/RS-422 level, inverting receiver input.
Y
±16.5kV IEC61000 ESD Protected RS-485/RS-422 level, non-inverting driver output.
Z
±16.5kV IEC61000 ESD Protected RS-485/RS-422 level, inverting driver output.
VCC
System power supply input (4.5V to 5.5V).
NC
No Connection.
