Description

2
RO
Receiver Output. When enabled, if A > B by 200 mV, then RO =
high. If A < B by 200 mV, then RO = low.
2
Not applicable
3
RE
Receiver Output Enable. A low level enables the receiver output,
RO. 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.
3
Not applicable
4
DE
Driver Output Enable. A high level enables the driver differential
Output A and Output B. 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.
4
3
5
DI
Driver Input. With a half-duplex part when the driver is enabled, a
logic low on DI forces A low and B high while 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 while a logic
high on DI forces Y high and Z low.
