Product Details
The ADM3070E–ADM3078E are 3.3V, low power data transceivers with ±15kV ESD protection suitable for full and half duplex communication on multipoint bus transmission lines. They are designed for balanced data transmission and comply with TIA/EIA standards RS-485 and RS-422. The devices have a 1/8 unit load receiver input impedance which allows up to 256 transceivers on a bus. Since only one driver should be enabled at any time, the output of a disabled or powered down driver is three-stated to avoid overloading the bus.
The receiver inputs have a true failsafe 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.
