GeneralGeneralGeneralGeneral The Toshiba TLP2303 consists of a high-output GaAAs light-emitting diode coupled with a high-speed photodiode- transistor chip. It is housed in the SO6 package. The high-speed, high-gain detector element is used, since the current transfer ratio is 900 % ( I = 0.5 mA) F minimum over -40 to 125 and thus is ideal for applications which require low input current and high-speed data transmission. TLP2303 corresponds to the transmission rate of 100 kbps, and has become a product which fills between a general-purpose transistor coupler and IC couplers corresponding to 1 Mbps. 3. 3.
