The SN55110A, SN75110A, and SN75112 dual
line drivers have improved output current
regulation with supply-voltage and temperature
variations. In addition, the higher current of the
SN75112 (27 mA) allows data to be transmitted
over longer lines. These drivers offer optimum
performance when used with the SN55107A,
SN75107A, and SN75108A line receivers.
