Description
Receiver Output. When enabled, if A > B by 200 mV, then RO = high.
If A < B by 200 mV, then RO = low.
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.
Driver Output Enable. A high level enables the driver differential Outputs A and 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.
Driver Input. 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.
Ground.
Noninverting Receiver Input A and Noninverting Driver Output A.
Inverted Receiver Input B and Inverted Driver Output B.
Power Supply, 3.3 V ± 0.3 V.
