Transistor Inverter

The TOSHIBA TLP2530 and TLP2531 dual photocouplers consist of a pair of GaAℓAs light emitting diode and integrated photodetector. This unit is 8−lead DIP.

Separate connection for the photodiode bias and output transistor collectors improve the speed up to a hundred times that of a conventional phototransistor coupler by reducing the base−collector capacitance.

• TTL compatible

• Switching speed: tpHL=0.3μs, tpLH=0.3μs(typ.) (@RL=1.9kΩ)
