Product Overview

The ADM3073EARZ is a low power Data Transceiver with ±15kV ESD protection suitable for full and half-duplex communication on multipoint bus transmission lines. It is designed for balanced data transmission and complies with TIA/EIA standards: RS-485 and RS-422. The device has 1/8 unit load receiver input impedance, which allows up to 256 transceivers on a bus. Because only one driver should be enabled at any time, the output of a disabled or powered-down driver is tri-stated to avoid overloading the bus. The receiver inputs have a true fail-safe feature, which eliminates the need for external bias resistors and ensures a logic high output level when the inputs are open or shorted. This guarantees that the receiver outputs are in a known state before communication begins and when communication ceases.
  • True failsafe receiver inputs
  • Hot-swap input structure on DE and RE pins
  • Reduced slew rates for low EMI
  • Low power shutdown current
  • Outputs high-Z when disabled or powered-OFF
  • Thermal shutdown and short-circuit protection
