DS75110A Datasheet | National Semiconductor

Description The DS75110A is a dual line driver with independent channels, mon supply and ground terminals featuring constant current outputs. These drivers are designed for optimum performance when used with the DS75107, DS75108 line receivers. The output current of the DS75110A is nominally 12 m A and may be switched to either of two output terminals with the appropriate logic levels at the driver input. Separate or mon control inputs are provided for increased 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, IO(Off), is specified so that minimum line loading is induced. This is highly desirable in system applications using party line data munications.
