Principio de funcionamiento<\/h2>\n

The ADM4852 uses a differential driver and receiver for noise-immune communication over twisted-pair cable. The driver produces a differential output of at least 1.5V across a 54-ohm load. The 1\/4 unit load receiver input impedance (96kOhm) allows 128 transceivers on a single bus vs. 32 with full unit load devices. Fail-safe biasing ensures the receiver output is logic high when the bus is open, shorted, or all drivers are disabled (idle). Enable pins (DE, RE) control driver and receiver independently for half-duplex operation.<\/p>\n
