2. General
The Toshiba TLP2161 consists of a high-output GaAℓAs light-emitting diode coupled with a high-speed photo-
diode-transistor chip. It is housed in the SO8 package. It has two circuits built into a single SO8 package, which
can reduce the mounting area.
This photocoupler guarantees operation at up to 125
and on supplies from 2.7 V to 5.5 V. Since TLP2161 has
guaranteed 2 mA low supply current (I
CCL
/I
CCH
), and 1.6 mA (T
a
= 125
)
low threshold input current(I
FHL
), it
contributes to energy saving of devices. It can drive directly from a microcomputer for a low input current.
The TLP2161 has an internal Faraday shield that provides a guaranteed common-mode transient immunity of
±20
kV/µs.

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 8 and pin 5 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: Each channel
Note 2: The rise and fall times of the input on-current should be less than 0.5
µs.
Note 3: Denotes the operating range, not the recommended operating condition.
