Description
Receiver Output. When enabled, if (A B) ≥ 50 mV, RO is high. If
(A B) ≤ 200 mV, RO is low.
Receiver Output Enable. A low level enables the receiver output.
A high level places it in a high impedance state. If RE is high and DE
is low, the device enters a low power shutdown mode.
Driver Output Enable. A high level enables the driver differential
A and B outputs. A low level places it in a high impedance state. If
RE is high and DE is low, the device enters a low power shutdown mode.
Driver Input. With a half-duplex part when the driver is enabled, a
logic low on DI forces A low and B high; a logic high on DI forces
A high and B low. With a full-duplex part when the driver is enabled,
a logic low on DI forces Y low and Z high; a logic high on DI forces
Y high and Z low.
Ground.
Noninverting Driver Output.
Noninverting Receiver Input A and Noninverting Driver Output A.
