iC-VX
3-CHANNEL DIFFERENTIAL LINE DRIVER
Rev C1, Page 6/11
APPLICATIONS INFORMATION
Line drivers for control engineering couple digital signals with TTL or CMOS levels via lines to 24V systems. Due
to possible line short circuits, the drivers are current-limited and shut down in the event of overtemperature.
The device iC-VX permits the operating points of the Schmitt trigger inputs to be shifted with the supply voltages
VCC and VEE, thus within the range of the output stage supply voltage VB.
The programming of the driver current to 30mA or 100mA permits optimum matching on the basis of line length
and required transmission rate. External series resistors must be provided for higher driver current to ensure
short-circuit strength in 24V applications. Furthermore, these series resistors improve the ability of the driver to
adapt to the line surge impedance.
