The TOSHIBA TLP621, −2 and −4 consists of a photo−transistor

optically coupled to a gallium arsenide infrared emitting diode.

The TLP621−2 offers two isolated channels in an eight lead plastic DIP,

which the TLP621−4 provides four isolated channels in a sixteen plastic

DIP.

· Collector−emitter voltage: 55 V (min.)

· Current transfer ratio: 50% (min.)

Rank GB: 100% (min.)
