| IL201/IL202/IL203 PHOTOTRANSISTOR OPTOCOUPLER FEATURES * High Current Transfer Ratio, 75% to 450% * Minimum Current Transfer Ratio, 10% * Guaranteed at IF=1mA * High Collector-Emitter Voltage, BVCEO=70V * Long Term Stability * Industry Standard DIP Package * Underwriters Lab File #E52744 * VDE 0884 Available with Option 1 DESCRIPTION The IL201/202/203 are optically coupled pairs employing a Gallium Arsenide infrared LED and a Silicon NPN phototransistor. Signal information, including a DC level, can be transmitted by the device while maintaining a high degree of electrical isolation between input and output. The IL201/202/ 203 can be used to replace relays and transformers in many digital interface applications, as well as analog applications such as CRT modulation.
