ADM3070E/ADM3071E/ADM3072E/ADM3073E/ADM3074E/ADM3075E/ADM3076E/ADM3077E/ADM3078E CIRCUIT DESCRIPTION The ADM307xE series are high speed transceivers for RS485 and RS-422 communications. Each device contains one driver and one receiver. All devices feature fail-safe circuitry, which guarantees a logic high receiver output when the receiver inputs are ...
