*1 Typical values at TA = 25C *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. *3 Test circuit for propagation delay time

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 F 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.

Rosin flux containing small amount of chlorine (The flux with a maximum chlorine content of 0.2 Wt% is recommended.) (3) Cautions * Fluxes Avoid removing the residual flux with freon-based and chlorine-based cleaning solvent.
2. Cautions regarding noise
Be aware that when voltage is applied suddenly between the photocoupler's input and output or between collector-emitters at startup, the output side may enter the on state, even if the voltage is within the absolute maximum ratings.
