Analog Devices ADM483
The ADM483 is a low power differential line transceiver suitable for half-duplex data communication on multipoint bus transmission lines. It is designed for balanced data transmission, and complies with EIA Standards RS-485 and RS-422.The part contains a differential line driver and a differential line receiver. Both share the same differential pins, with either the driver or the receiver being enabled at any given time.- Min Voltage : 4.5V
- Max Voltage : 5.5V
- Max Operating Temp : 85°C
- Min Operating Temp : -40°C

The device has an input impedance of 12 kΩ, allowing up to 32 transceivers on one bus. Since only one driver should be enabled at any time, the output of a disabled or powered-down driver is three-stated to avoid overloading the bus. This high impedance driver output is maintained over the entire common-mode voltage range from –7 V to +12 V.
