Tue, 07/08/2008 - 7:11am

Fairchild FOD07xxHaving a minimum common mode noise rejection rating of 20 kV/µs, Fairchild Semiconductor’s FOD07xx Series logic gate optocouplers provide bandwidth yielding 25 Mbps. The J-STD-020- and UL1577-standardized devices consist of a high-speed AiGaAs LED driven by a CMOS IC and utilize lead-free (Pb-free) terminals. The RoHS-compliant optocouplers have a propagation delay of 40 ns max, 5-V CMOS compatibility, a temperature range from -40°C to 100°C, and pulse width distortion of 6 or 8 ns, depending on model. The devices are well suited for industrial communication standards, such as Profibus, DeviceNet, CAN, and RS485. Pricing is $2.67 for the FOD0721, $2.44 for the FOD0720, and $.2.21 for the FOD0710 in 1,000 quantities each.
