ADM3072EARZ

ADM3072EARZ is a 3.3V RS-485/RS-422 transceiver from Analog Devices designed for half-duplex communication on multipoint buses. It supports a data rate of 250 kbps and integrates one driver and one receiver. The transceiver includes true fail-safe receiver inputs, receiver hysteresis of 100 mV, and a common-mode input range of -7V to +12V, enabling reliable data transfer in electrically noisy environments.

Built-in ±15kV ESD protection on the RS-485 input/output pins and a hot-swap input structure on the DE and RE pins support robust live-insertion designs. The device draws a maximum supply current of 1.5mA and includes low shutdown current, making it well suited for power-sensitive applications. Short-circuit protection and thermal shutdown are provided as safety features.

With ⅛ unit load receiver input impedance, the ADM3072EARZ can support up to 256 transceivers on a single bus. The driver outputs are 3-state, allowing shared bus access when disabled. Packaged in an 8-lead SOIC, the transceiver is designed for surface-mount assembly and is RoHS compliant. It operates over a temperature range of -40°C to +125°C, making it suitable for industrial and commercial applications.
