TLP2166A is a photocoupler produced by Toshiba. It consists of a GaAℓAs light emitting diode and an integrated high-gain, high-speed photodetector. The TLP2166A is housed in the 8-pin SO package. Since the TLP2166A contains two photocouplers, it saves board space. The TLP2166A operates with a 3.3V supply voltage.
The Toshiba TLP2166A is an 8‑pin SO optocoupler that combines a GaAs LED with a high‑gain, high‑speed photodetector. It operates from a 3.0 V to 3.6 V supply and provides an inverting logic output with a typical switching time of 75 ns.
