The Toshiba TLP108 consists of a GaAℓAs light emitting diode optically coupled to a high-gain, high-speed photodetector. The TLP108 is housed in a 6-pin MFSOP.
With a totem-pole output, the TLP108 is capable of both sinking and sourcing current. The TLP108 has an internal Faraday shield, which provides a guaranteed common-mode transient immunity of ±10 kV/μs. The TLP108 has an inverting output. A noninverting-output version, the TLP105, is also available.
