Description
Power Supply (Logic Side), 3 V or 5 V Supply. Decoupling capacitor to GND
between 0.01 μF and 0.1 μF.
Ground (Logic Side).
Receiver Output Data. This output is high when (A – B) > 200 mV and low when (A – B) < –200 mV. The output
is three-stated when the receiver is disabled, that is, 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.
Request to Send 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, needs to be tied high when the ADM2486 is operational,
see the Applications Information section.
Ground (Bus Side).
Driver Enable Status Output. This output signals the driver enable or disable status to other devices on the bus.
DE is high when the driver is enabled and low when the driver is disabled.
No Connect.
Noninverting Driver Output/Receiver Input. When the driver is disabled, or when V
Pin A is put into a high impedance state to avoid overloading the bus.
Inverting Driver Output/Receiver Input. When the driver is disabled, or when V
Pin B is put into a high impedance state to avoid overloading the bus.
Power Supply (Bus Side), 5 V Isolated Supply. Decoupling capacitor to GND
between 0.01 μF and 0.1 μF.
