Dual Differential (EIA-422-A)/Quad Single Ended (EIA-423-A) Line Driver

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.
