Описание

The ADM4850ARZ is a Differential Line Transceiver for high speed half-duplex data communication on multipoint bus transmission lines. It is designed for balanced data transmission and complies with EIA Standards RS-485 and RS-422. It shares differential lines and have separate enable inputs for the driver and receiver. The device has a 1/8-unit load receiver input impedance, which allows up to 256 transceivers on one bus. Because only one driver must be enabled at any time, the output of a disabled or powered down driver is 3-stated to avoid overloading the bus. The receiver inputs have a true fail-safe feature, which 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 ends. The driver outputs are slew rate limited to reduce EMI and data errors caused by reflections from improperly terminated buses.

• Reduced slew rates for low electromagnetic interference
• True failsafe receiver inputs
• 5µA Maximum supply current in shutdown mode
• Outputs high-Z when disabled or powered-OFF
• Thermal shutdown and short-circuit protection
• Pin-compatible with the MAX308x
• Up to 256 transceivers on one bus
