FOD2200 Low Input Current Logic Gate Optocouplers Features Description ■ 1kV/µs minimum common mode rejection 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. ■ 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 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. ■ Safety approvals pending – UL, CSA, VDE ■ VISO = 5kVRMS Applications ■ Isolation of high speed logic systems ■ Computer peripheral interfaces ■ Microprocessor system interfaces ■ Ground loop elimination ■ Pulse transformer replacement ■ Isolated bus driver Truth Table (Positive Logic) ■ High speed line receiver LED Enable Output On H Z Off H Z On L H Off L L Functional Block Diagram and Schematic Package Outlines ICC 8 VCC NC 1 8 IF 7 VO ANODE 2 6 VE CATHODE 3 + VF SHIELD 6 3 5 GND SHIELD 8 1 7 IE – NC 4 IO 2 VCC 5 VO VE GND 8 8 1 ©2004 Fairchild Semiconductor Corporation FOD2200 Rev. 1.0.1 1 www.fairchildsemi.com FOD2200 — Low Input Current Logic Gate Optocouplers August 2008 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.

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. ©2004 Fairchild Semiconductor Corporation FOD2200 Rev. 1.0.1 www.fairchildsemi.com 4 FOD2200 — Low Input Current Logic Gate Optocouplers Electrical Characteristics (Continued) FOD2200 — Low Input Current Logic Gate Optocouplers Test Circuits PULSE GEN. t r = t f = 5 ns f = 100 kHz 10 % DUTY CYCLE VO = 5 V IF INPUT MONITORING NODE R1 VCC OUTPUT VO MONITORING NODE FOD2200 1 VCC 8 2 7 3 6 5V 619 Ω D1 D2 C2 = 15 pF GND 5 4 C1 = 120 pF D3 5 kΩ D4 THE PROBE AND JIG CAPACITANCES ARE INCLUDED IN C 1 AND C2. 2.15 kΩ 1.10 kΩ 681 Ω RI 5 mA IF (ON) 1.6 mA 3 mA ALL DIODES ARE 1N916 OR 1N3064.

ANTI-COUNTERFEITING POLICY Fairchild Semiconductor Corporation's Anti-Counterfeiting Policy. Fairchild's Anti-Counterfeiting Policy is also stated on our external website, www.fairchildsemi.com, under Sales Support. Counterfeiting of semiconductor parts is a growing problem in the industry. All manufacturers of semiconductor products are experiencing counterfeiting of their parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed applications, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild Distributors are genuine parts, have full traceability, meet Fairchild's quality standards for handling and storage and provide access to Fairchild's full range of up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address any warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
