2. General
The TLP2370 is a 20-Mbps low-power photocoupler in the small SO6 package.
The TLP2370 consumes supply current (I
DDL
/I
DDH
) of only 0.4 mA maximum over the entire operating
temperature range of -40
to 125
and operates at a supply voltage as low as 2.7 V, contributing to a reduction
in power consumption of various systems.
The input forward current can be 1.3 mA for minimum, allowing direct drive by a microcontroller.
The detector has a totem-pole output stage with current sourcing and sinking capabilities. The TLP2370 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 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.
When a peaking capacitor is placed at input side, V
IN
should be less than 5.5 V, R
IN
should be less than
2.7 kΩ, C
IN
should be less than 22 pF.
Note 2: Denotes the operating range, not the recommended operating condition.
