2. General
The Toshiba TLP2745 consists of high-output GaAℓAs light-emitting diode coupled with a high-gain, high-speed
photo detector. It is housed in a thin SO6L package of 2.3 mm (max). The TLP2745 has guaranteed the isolation
voltage 5 kVrms and compliant with international safety standards for reinforced insulation. This product can
operate in power supply voltage 4.5 V to 30 V with the maximum operative temperature of 110
.
Since TLP2745
has guaranteed 3 mA low supply current (I
CCL
/I
CCH
), and 1.6 mA low threshold input current(I
FLH
), it contributes
to energy saving of devices. It can drive directly from a microcomputer for a low input current. The detector has
a totem-pole output stage with current sourcing and sinking capabilities. The TLP2745 has an internal Faraday
shield that provides a guaranteed common-mode transient immunity of
±30
kV/µs. The TLP2745 has a buffer
output. An inverter output version, the TLP2748, is also available.

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).

The recommended operating conditions are given as a design guide necessary to obtain the intended
performance of the device. Each parameter is an independent value. When creating a system design using
this device, the electrical characteristics specified in this data sheet should also be considered.
Note: A ceramic capacitor (0.1
µF)
should be connected between pin 6 and pin 4 to stabilize the operation of a high-
gain linear amplifier. Otherwise, this photocoupler may not switch properly. The bypass capacitor should be
placed within 1 cm of each pin.
Note 1: The rise and fall times of the input on-current should be less than 0.5
µs.
Note 2: Denotes the operating range, not the recommended operating condition.
