The 26LS30 Dual Differential RS422 RS423 Line Driver is a low-power Schottky set of line drivers which can be configured as two differential drivers which comply with EIA−422−A standards, or as four single−ended drivers which comply with EIA−423−A standards. A mode select pin and appropriate choice of power supplies determine the mode. Each driver can source and sink currents in excess of 50 mA.
