55109 75109 55110 + 75110 DUAL LINE DRIVERS FAIRCHILD LINEAR INTEGRATED CIRCUITS GENERAL DESCRIPTION The 55109/75109 and 56110/75110 are Dual Line Drivers featuring independent channels with common supply voltage and ground terminals. The major difference between the 55109/75109 and the 55110/75110 drivers is the output-current specification. The output current is nominally 6 mA for the 55109/75109 and 12 mA for the 55110/75110. The driver circuits have a constant output that is switched to either of two output terminals by the appropriate logic levels at the input terminals. The output current can be switched off by appropriate logic levels at the inhibit inputs. The circuit also features an inhibit input that is common to both drivers, providing more circuit versatility. The common-mode voltage range of the driver outputs is 3.0 V to +10 V, which allows a common-mode voitage on the line without affecting the driver performance, For application information see 551074 @ 75107A @ 55108A @ 75108A data sheet.

Coaxial or shielded line is preferred for minimum noise and cross-talk problems, For targe signal swings, the high output current (12 mA} of the 55110/75110 is recommended. Drivers may be parallelied for higher current. The unused driver output must be tied to ground. The following precaution should be observed when using or testing 55/75109 and 55/75110 dual line drivers. When only one driver in a package is being used, the outputs of the other driver must either be grounded or inhibited in order to prevent excess power dissipation. 6-48
