The Toshiba TLP293-4(GB,E is a four-channel transistor output optocoupler manufactured by Toshiba. It offers broad compatibility with both digital and analog circuits, as well as a wide range of applications. It features a built-in LED and a phototransistor, which isolates the two input/output circuits and blocks high-frequency noise. The photo transistor output of the TLP293-4(GB,E is designed to efficiently switch and drive a wide range of load circuits with low saturation voltage and low output current. It has an operating temperature range of -40°C to +125°C and a 13KV surge voltage. The TLP293-4(GB,E can be used for power supply voltage monitoring, switching, and driving circuits with up to 200 mA current load.
