TOSHIBA PHOTOCOUPLER GaAℓAs Ired & PHOTO-IC
TLP2108
Isolated Bus Drivers
High Speed Line Receivers
Microprocessor System Interfaces
The Toshiba TLP2108 consists of GaAℓAs light emitting diodes and
integrated high-gain, high-speed photodetectors.
The TLP2108 is housed in the SO8 package.
The photodetector has a totem-pole output stage that can source and sink
current.
The photodetector has an internal Faraday shield that provides a
guaranteed common-mode transient immunity of ±10 kV/μs.
The TLP2108 provides an inverting logic output. A noninverting logic
version, the TLP2105, is also available.
Inverting logic output (totem-pole output)
Guaranteed performance over −40 to 100°C
Power supply voltage: 4.5 to 20 V
Input threshold current: I

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if
the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings.
Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook
(“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e. reliability test
report and estimated failure rate, etc).
Note 1: Each Channel.
Note 2: Pulse width ≤ 1μs, 300 pps.
Note 3: This device is regarded as a two terminal device: pins 1, 2, 3 and 4 are shorted together,
as are pins 5, 6, 7 and 8.
