TOSHIBA Photocoupler GaA As Ired Photo IC TLP2530 TLP2531 Manual(1)(1)

TLP2530,TLP2531 is a dual photocoupler from TOSHIBA, consisting of a pair of GaAℓAs light emitting diodes and integrated photodetectors. This unit is an 8-lead DIP package. 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.
