Notes*: 1. Typical values at TA = 25 °C.

2. Because VOL of 2 V or more may be output when LED current is input and when output power supply is on

and off, confirm the characteristics (operation with the power supply on and off) during design, before using

this device.

3. Test circuit for propagation delay time

Remark: CL includes probe and stray wiring capacitance.

4. Test circuit for common mode transient immunity

Remark: CL includes probe and stray wiring capacitance.

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 more than 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. Pins 1, 4 (which is an NC*1 pin) can either be connected directly to the GND pin on the LED side or left

open. Also, Pin 7 (which is an NC*1 pin) can either be connected directly to the GND pin on the detector

side or left open.

Unconnected pins should not be used as a bypass for signals or for any other similar purpose because

this may degrade the internal noise environment of the device.

NC: Non-Connection (No Connection)

4. Avoid storage at a high temperature and high humidity.

5. Avoid cleaning with Freon based or halogen-based (chlorinated etc.) solvents.

6. Do not use fixing agents or coatings containing halogen-based substances.
