Overview
The MC26LS30DR2, produced by onsemi, is a low power Schottky set of line drivers that can be configured as either two differential drivers complying with EIA-422-A standards or four single-ended drivers complying with EIA-423-A standards. The configuration is determined by a mode select pin and the choice of power supplies. Each driver can source and sink currents in excess of 50 mA. The device is available in a 16-pin surface mount package and operates over a temperature range of -40°C to +85°C.
