Hot-selling and scarce ADM3483EARZ RS-485/RS-422 Transceivers SOP8 spot stock

Product Descriptions

The ADM3483E/ADM3486E/ADM3488E/ADM3490E/ADM3491E are 3.3 V, low power data transceivers with±15 kV ESD protection suitable for full- and half-duplex communication on multipoint bus transmission lines. They are designed for balanced data transmission, and they comply with TIA/EIA standards RS 485 and RS-422 . The ADM3483E/ADM3486E are half-duplex transceivers that share differential lines and have separate enable inputs for the driver and receiver. The full-duplex ADM3488E/ ADM3490E/ADM3491E transceivers have dedicated differential line driver outputs and receiver inputs. The ADM3491E also features separate enable inputs for the driver and 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.
