The ADM483EAR is a 5V, low power data transceiver designed for half-duplex communication on multipoint bus transmission lines. It complies with TIA/EIA Standards RS-485 and RS-422, supporting up to 32 transceivers on a single bus. The device features ±15 kV ESD protection on the transceiver outputs, ensuring robust operation in electrically harsh environments.
Key electrical specifications include a 250 kbps data rate with reduced slew rate for low electromagnetic interference, a supply voltage range of 4.5V to 5.5V, and a typical supply current of only 36 µA. A shutdown mode reduces current consumption to 0.1 µA. The receiver includes an open-circuit fail-safe design, and the driver outputs are short-circuit protected with thermal shutdown.
The ADM483EAR is available in a surface mount 8-SOIC package with a 3.90mm width. It is suitable for low power RS-485 systems, EMI sensitive applications, and DTE-DCE interfaces.
The supply voltage range is 4.5V to 5.5V.
The maximum data rate is 250 kbps.
The ADM483EAR provides ±15 kV ESD protection.
Up to 32 transceivers can be connected on the bus.
The ADM483EAR is available in an 8-SOIC surface mount package.
The ADM483EAR is listed as RoHS3 Compliant, though this is unverified.
The typical supply current is 36 µA during normal operation.
