Description
Power Supply (Logic Side).
Ground (Logic Side).
Receiver Output Data. This output is high when (A B) > 200 mV, and low when (A B) < 200 mV.
There is tristate output when the receiver is disabled, i.e., when RE is driven high.
Receiver Enable Input. This is an active-low input. Driving this input low enables the receiver, and
driving it high disables the receiver.
Driver Enable Input. Driving this input high enables the driver, and driving it low disables the driver.
Transmit Data Input. Data to be transmitted by the driver is applied to this input.
Power Valid. Used during power-up and power-down. See the Applications Information section.
Ground (Bus Side).
No Connect.
Noninverting Driver Output/Receiver Input. When the driver is disabled, or V
DD1
or V
DD2
is powered
down, Pin A is put in a high impedance state to avoid overloading the bus.
