Product details

25Mbps logic isolator in 8-SOIC

The FOD0720 is a single-channel, logic-input optoisolator from onsemi rated for 25Mbps data rate with a push-pull, totem-pole output that eliminates the need for an external pull-up resistor on the output side. The 3750Vrms isolation rating suits it for breaking ground loops in industrial digital interfaces like CAN, RS-485, and SPI lines where the signal rate exceeds what a standard photocoupler can pass.

Active production, tube delivery

The 8-SOIC package is a standard footprint shared by many logic optoisolators, so the board layout is straightforward.

Supply rail and temperature range

The part operates from a 4.5V to 5.5V supply on both sides — it is a 5V-logic part, not 3.3V-compatible without a level shifter. The industrial temperature range of -40°C to 100°C covers most factory-floor and outdoor telecom enclosures without forced cooling. Rise and fall times are 5ns and 4.5ns typical, which keeps the output edges clean for driving CMOS or TTL inputs directly.

Frequently asked questions

Is the FOD0720 compatible with 3.3V logic?

No — the supply voltage range is 4.5V to 5.5V, so the input and output logic levels are 5V. For 3.3V systems, you would need a level translator between the 3.3V logic and the FOD0720 input, or look at a 3.3V-rated optoisolator such as the FOD8001R2 which also runs at 25Mbps but has a wider supply range.

Does the FOD0720 require an external pull-up resistor on the output?

No — the output is push-pull, totem pole, which means it actively drives high and low. Unlike open-collector optoisolators, you do not need a pull-up resistor on the output side, saving one component per channel.
