TLP108
TOSHIBA PHOTOCOUPLER GaAℓAs IRED & PHOTO-IC
TLP108
Unit in mm
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.

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: Pulse width ≤ 1μs, 300pps.
Note 2: Pulse width ≤ 5μs, duty cycle ≤ 0.025
Note 3: Device considered a two terminal device: pins 1 and 3 shorted together and pins 4, 5 and 6 shorted together.

Note 5: A ceramic capacitor (0.1μA) should be connected from pin 6 to pin 4 to stabilize the operation of the high
gain linear amplifier. Failure to provide the bypassing may impair the switching property. The total lead length
between capacitor and coupler should not exceed 1 cm.
