The TOSHIBA TLP523, −2 and −4 consists of a gallium arsenide infrared emitting diode coupled with a silicon, darlington connected, phototransistor which has an integral base−emitter resistor to optimize switching speed and elevated temperature characteristics.
The TLP523−2 offers two isolated channels in an eight lead plastic DIP package, while the TLP523−4 provide four isolated channels per package.
