TLP2530 and TLP2531 are dual photocouplers from TOSHIBA, consisting of a pair of GaAℓAs light emitting diodes and integrated photodetectors. This unit is an 8-lead DIP package. The speed is improved up to a hundred times that of a conventional phototransistor coupler by reducing the base-collector capacitance. It is TTL compatible, has fast switching speed, guaranteed performance over a wide temperature range, high isolation voltage, and is UL recognized.
The TLP2530 and TLP2531 are dual GaAlAs light‑emitting diode and photodetector photocouplers in an 8‑lead DIP package. They offer high‑speed isolation with separate photodiode bias and output transistor connections, achieving switching speeds of 0.3 µs (typ.).
The datasheet lists maximum ratings, recommended operating conditions, electrical and switching characteristics, and safety restrictions for use in general electronics applications such as computers, office equipment, and industrial robotics.
