Pin 8 (RS) is used to select the operating mode. access the physical layer bus. The ADM3051 complies with The low current standby mode can be selected by applying a the ISO 11898 standard. It is capable of running at data rates up logic high to RS. to 1 Mbps. The device can be set to operate with slope control to limit EMI The device has current-limiting and thermal shutdown features by connecting RS with a resistor to ground to modify the rise to protect against output short circuits and situations where the and fall of slopes. This mode facilitates the use of unshielded bus may be shorted to ground or power terminals in 24 V bus cables. Alternatively, disabling slope control by connecting RS power systems. The part is fully specified over the industrial to ground allows high speed operation. Shielded cables or other temperature range of 40C to +125C and is available in an measures to control EMI are necessary in this mode. 8-lead SOIC package. Rev.
