DUAL DIFFERENTIAL/
QUAD SINGLE–ENDED
LINE DRIVERS
The AM26LS30 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.
