illustrate

The FOD2200 is an optocoupled logic gate combining an AlGaAs LED and an integrated high gain photodetector. The detector has three-state outputs and a detector threshold with hysteresis. This tri-state output eliminates the need for pull-up resistors and allows direct driving of the data bus. Hysteresis provides differential mode immunity and eliminates the possibility of output signal jitter. The electrical and switching characteristics of the FOD2200 are guaranteed at 0°C to 85°C with a VCC range of 4.5V to 20V. The low IF and wide VCC range allow with TTL, LSTTL and CMOS logic to reduce power consumption compared to other high speed optocouplers. Logic signals are transmitted with maximum propagation. Delay 300ns. The FOD2200 is used to isolate high-speed logic interfaces, input and output buffered lines, and to isolate line-receiver noise environments at high levels.

Safety and Insulation Classes

Complies with IEC 60747-5-2. This optocoupler is only suitable for "safe electrical isolation" within the safety limit data. Compliance with the safety class shall be ensured by means of protective circuits.

Absolute Maximum Ratings (TA = 25°C unless otherwise noted)

Stresses in excess of the Absolute Maximum Ratings may damage the device. Equipment may not work or be recommended for operation under recommended operating conditions and increase component stress to these levels. Additionally, prolonged exposure to stresses higher than recommended operating conditions may affect device reliability. Absolute Maximum Ratings are for stress ratings only.

Recommended Operating Conditions

The Recommended Operating Conditions table defines the conditions for actual equipment operation. Recommendations specify operating conditions to ensure optimum performance to data sheet specifications. Fairchild does not recommend exceeding or designing to absolute maximum ratings.

The initial switching threshold is less than or equal to 1.6mA. 2.2mA is recommended to allow at least 20% CTR degradation protection and.

notes:

1. The VCC supply of each opto-isolator must be bypassed by a 0.1µF or larger capacitor. This can be a ceramic or solid tantalum capacitor with good high frequency characteristics and should be connected as closely as possible to the VCC and GND pins of each device.

2. tPLH – Propagation delay is measured at the 50% level of the low-to-high transition of the input current pulse at the 1.3V level on the low-to-high transition of the output voltage pulse.

3. tPHL – Propagation delay is measured at the 50% level of the input current pulse high-to-low transition of the output voltage pulse from high-to-low transition to the 1.3V level.

4. When the peak capacitance is omitted, the propagation delay time can be increased by 100ns.

5.tr – Rise time is measured from 10% to 90% level as the output pulse transitions from low to high.

6. Transfer Factor – The fall time is measured between 90% and 10% of the output pulse transitioning from high to low.

7.CMH - The maximum tolerable rate of common mode voltage drop to ensure the output will remain high. status (ie VOUT>2.0V).

8. CML - The maximum tolerable rate of common mode voltage rise to ensure the output will remain low. state (ie VOUT < 0.8V).

10. The output short circuit time should not exceed 10ms.
