DS75110A
Dual Line Drivers
General Description
The DS75110A is a dual line driver with independent chan-
nels, common supply and ground terminals featuring con-
stant current outputs. These drivers are designed for opti-
mum performance when used with the DS75107, DS75108
line receivers.
The output current of the DS75110A is nominally 12 mA and
may be switched to either of two output terminals with the
appropriate logic levels at the driver input.
Separate or common control inputs are provided for in-
creased logic versatility. These control or inhibit inputs allow
the output current to be switched off (inhibited) by applying
low logic levels to the control inputs. The output current in
the inhibit mode, I_O(Off), is specified so that minimum line
loading is induced. This is highly desirable in system applica-
tions using party line data communications.
