The TOSHIBA TLP320, −2 and −4 consists of a photo−transistor
optically coupled to a gallium arsenide infrared emitting diode.
The TLP320−2 offers two isolated channels in an eight lead plastic DIP
package, while the TLP320−4 provides four isolated channels in a
sixteen plastic DIP package. This is suitable for application of AC input
current up to 150mA.
IF maximum rating: ±150mA
Collector−emitter voltage: 55V (min.)
Current transfer ratio: 25% (min.) (IF = 20mA)
Isolation voltage: 5000Vrms (min.)
