[GENERAL INSTRUMENT]

DESCRIPTION
The MCA11G1 and MCA11G2 are the photodarlington-type optically coupled optocouplers. Both devices have a gallium arsenide infrared emitting diode coupled with a silicon darlington connected phototransistor which has an integral base-emitter resistor to optimize elevated temperature characteristics.

■ High BVCEO
   Minimum 100 V for MCA11G1
   Minimum 80 V for MCA11G2
■ Pin for pin replacement for H11G1, H11G2, H11G3
■ High sensitivity to low input current - Minimum
   500 percent CTR at IF = 1 mA
■ High isolation voltage
   2500 VAC RMS - Steady State Rating
■ Low leakage current at elevated temperature
