TOSHIBA PHOTOCOUPLER GaAℓAs IRED & PHOTO-IC

TLP108

Isolated bus drivers

High speed line receivers

Microprocessor system interfaces

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.

Inverter logic type (totem-pole output)
