The Toshiba TLP718 consists of a GaAℓAs light-emitting diode and an
integrated high-gain, high-speed photodetector. This unit is a 6-pin SDIP. The
TLP718 is 50% smaller than the 8-PIN DIP and meets the reinforced insulation
class requirements of international safety standards. Therefore the mounting
area can be reduced in equipment requiring safety standard certification.
The detector has a totem pole output stage to provide both source and sink
driving. The detector IC has an internal shield that provides a guaranteed
common-mode transient immunity of 10 kV / μs.
The TLP718 is inverter logic type. For buffer logic type, the TLP715 is in
line-up.

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 PW ≤ 1us, 300pps.
Note 2: Device Considered a two terminal device : pins 1,2 and 3 shorted together and pins 4,5 and 6 shorted
together.

value. (e.g.at a standard distance between soldering eye centres of 7.5mm). If this is not permissible,
the user shall take suitable measures.
2．This photocoupler is suitable for ‘safe electrical isolation’ only within the safety limit data.
Maintenance of the safety data shall be ensured by means of protective circuits.
