FOD2200 — Low Input Current Logic Gate Optocouplers
August 2008
FOD2200 Low Input Current Logic Gate Optocouplers
Features
■ 1kV/µs minimum common mode rejection ■ Compatible with LSTTL, TTL, and CMOS logic ■ Wide VCC range (4.5V to 20V) ■ 2.5Mbd guaranteed over temperature ■ Low input current (1.6mA) ■ Three state output (no pullup resistor required) ■ Guaranteed performance from 0°C to 85°C ■ Hysteresis ■ Safety approvals pending – UL, CSA, VDE ■ VISO = 5kVRMS
Description
The FOD2200 is an optically coupled logic gate that combine an AlGaAs LED and an integrated high gain photo detector. The detector has a three state output stage and has a detector threshold with hysteresis. The three state output eliminates the need for a pullup resistor and allows for direct drive of data busses. The hysteresis provides differential mode noise immunity and eliminates the potential for output signal chatter. The Electrical and Switching Characteristics of the FOD2200 are guaranteed over the temperature range of 0°C to 85°C and a VCC range of 4.5V to 20V. Low IF and wide VCC range allow compatibility with TTL, LSTTL, and CMOS logic and result in lower power consumption compared to other high speed opto-couplers. Logic signals are transmitted with a maximum propagation delay of 300ns. The FOD2200 is useful for isolating high speed logic interfaces, buffering of input and output lines, and implementing isolated line receivers in high noise environments.
Applications
■ Isolation of high speed logic systems ■ Computer peripheral interfaces ■ Microprocessor system interfaces ■ Ground loop elimination ■ Pulse transformer replacement ■ Isolated bus driver ■ High speed line receiver

Absolute Maximum Ratings (TA = 25°C unless otherwise specified)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.

*Typical values at TA = 25°C, VCC = 5V, IF(ON) = 3mA unless otherwise stated. Notes: 1. The VCC supply to each optoisolator must be bypassed by a 0.1µF capacitor or larger. This can be either a ceramic or solid tantalum capacitor with good high frequency characteristic and should be connected as close as possible to the package VCC and GND pins of each device. 2. tPLH – Propagation delay is measured from the 50% level on the LOW to HIGH transition of the input current pulse to the 1.3V level on the LOW to HIGH transition of the output voltage pulse. 3. tPHL – Propagation delay is measured from the 50% level on the HIGH to LOW transition of the input current pulse to the 1.3V level on the HIGH to LOW transition of the output voltage pulse. 4. When the peaking capacitor is omitted, propagation delay times may increase by 100ns. 5. tr – Rise time is measured from the 10% to the 90% levels on the LOW to HIGH transition of the output pulse. 6. tf – Fall time is measured from the 90% to the 10% levels on the HIGH to LOW transition of the output pulse. 7. CMH – The maximum tolerable rate of fall of the common mode voltage to ensure the output will remain in the high state (i.e., VOUT > 2.0V). 8. CML – The maximum tolerable rate of rise of the common mode voltage to ensure the output will remain in the low state (i.e., VOUT < 0.8V). 9. Device considered a two-terminal device: Pins 1, 2, 3 and 4 shorted together, and Pins 5, 6, 7 and 8 shorted together. 10. Duration of output short circuit time should not exceed 10ms.
