MC26LS30 Dual Differential (EIA-422-A)/ Quad Single-Ended (EIA-423-A) Line Drivers
The MC26LS30 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. In the differential mode (EIA–422–A), the drivers can be used up to 10 Mbaud. A disable pin for each driver permits setting the outputs into a high impedance mode within a +10 V common mode range. In the single–ended mode (EIA–423–A), each driver has a slew rate control pin which permits setting the slew rate of the output signal so as to comply with EIA–423–A and FCC requirements and to reduce crosstalk. When operated from symmetrical supplies (+5.0 V), the outputs exhibit zero imbalance The MC26LS30 is available in a 16–pin surface mount package. Operating temperature range is –40° to +85°C.
