*1 Typical values at TA = 25°C
*2 Because VOL of 2 V or more may be output when LED current input and when output supply of VCC = 2.6 V or
less, it is important to confirm the characteristics (operation with the power supply on and off) during design,
before using this device.

USAGE CAUTIONS
1. This product is weak for static electricity by designed with high-speed integrated circuit so protect against static
electricity when handling.
2. By-pass capacitor of 0.1 μF is used between VCC and GND near device. Also, ensure that the distance between
the leads of the photocoupler and capacitor is no more than 10 mm.
3. Avoid storage at a high temperature and high humidity.
