Description
The coupler consists of an AlGaAs LED that is optically coupled to a dielectrically isolated photodiode array
which drives two series connected high voltage MOS transistors. The typical ON-Resistances (see table) of
20 or 40 ohms at 25mA are linear up to 50 mA; the incremental resistance drops to less than 20 to 40 ohms
beyond 50 mA while reducing internal power dissipation at high load currents.
Applications
Telecommuncations - Telecom Switching; Tip/Ring Circuits; Modem Switching (Laptop, Notebook, Pocket
Size); Hookswitch; Dial Pulsing; Ground Start; Ringer Injection
Instrumentation - Multiplexers; Data Acquisition; Electronic Switching; I/O Subsystems; Meters (Watt-Hour,
Water, Gas); Medical Equipment
Miscellaneous - High Voltage Test Equipment; Triac Driver; Motor Control; Security; Aerospace; Industrial
Controls
