Part Number : ADM4850
Function : 5 V, Slew-Rate Limited, Half-Duplex and Full-Duplex RS-485 / RS-422 Transceiver
Package : 8-lead SOIC, LFCSP, and MSOP Type
Maker : Analog Devices
Pinouts : 
Description :
The ADM4850 / ADM4851 / ADM4852 / ADM4853 / ADM4854 / ADM4855 / ADM4856 / ADM4857 are differential line transceivers suitable for high speed half- and full-duplex data communication on multipoint bus transmission lines. They are designed for balanced data transmission and comply with EIA Standards RS-485 and RS-422. The ADM4850/ADM4851/ADM4852/ADM4853 are half-duplex transceivers that share differential lines and have separate enable inputs for the driver and receiver.
The full-duplex ADM4854/ADM4855/ADM4856/ADM4857 transceivers have dedicated differential line driver outputs and receiver inputs. The parts have a 1/8-unit-load receiver input impedance, which allows up to 256 transceivers on one bus. Because 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.
