ADM483EAR

The ADM483EAR is a 5V, low-power data transceiver from Analog Devices, featuring ±15 kV ESD protection. It is designed for half-duplex communication on multipoint bus transmission lines and complies with TIA/EIA Standards RS-485 and RS-422.

This transceiver supports a data rate of 250 kbps and operates on a single 5V ±10% supply. It offers a wide bus common-mode range of -7V to +12V and can accommodate up to 32 transceivers on a bus. The ADM483EAR includes a low current shutdown mode, consuming only 0.1 µA. Drivers are short-circuit current-limited and protected by thermal shutdown circuitry.

The receiver input features an open-circuit, fail-safe design, ensuring a logic high output if the input is open. This makes it suitable for applications in electrically harsh environments and EMI-sensitive applications. The device is available in an 8-lead SOIC_N package and is fully specified over industrial temperature ranges.

Key features include reduced slew rate for low EM interference, receiver open-circuit fail-safe, and short-circuit protection. The ADM483EAR is an ideal choice for low power RS-485 systems, DTE-DCE interfaces, packet switching, and local area networks.
