The TLP114A is a small outline coupler suitable for surface mount assembly. It consists of a high output power GaAℓAs light emitting diode optically coupled to a high-speed detector of one chip photodiode-transistor. Isolation voltage: 3750 Vrms (min.). Switching speed: tpHL = 0.8µs, tpLH = 0.8µs (max.). TTL compatible.
The TLP114A is a miniature surface‑mount GaAs optocoupler that combines a high‑output light‑emitting diode with a fast photodiode‑transistor detector. It is intended for digital logic isolation, power‑supply feedback, and switching applications.
The document lists maximum ratings, electrical characteristics, switching times, and recommended operating conditions, including an isolation voltage of 3750 Vrms, propagation delay of 0.8 µs, and a supply voltage range of 0.5‑30 V. Safety and handling notes are also provided.
