The ADM3485EARZ-REEL7 is a 3.3 V, low power data transceiver with
±15 kV ESD protection, suitable for half-duplex communication on multipoint bus transmission lines. The ADM3485EARZ-REEL7
is designed for balanced data transmission and complies with
TIA/EIA standards RS485 and RS-422. The ADM3485EARZ-REEL7 is a
half-duplex transceiver that shares differential lines and has
separate enable inputs for the driver and the receiver.
The devices have a 12 kΩ receiver input impedance, which
allows up to 32 transceivers on a bus. Because only one driver should be enabled at any time, the output of a disabled or
powered-down driver is tristated to avoid overloading the bus.
As a professional Analog Devices Inc distributor, Nantian Electronics has a large number of ADM3485EARZ-REEL7 in stock. We also provide ADM3485EARZ-REEL7 parameters, ADM3485EARZ-REEL7 Datasheet PDF and pin diagram instructions for download.
