N EC H I G H S P E E D O P TO C O U P L E R S N EC HIGH SPEED OPTOCOUPLERS NEC High Speed Optocouplers offer best in class performance and reliability NEC offers a broad range of high speed digital and analog optocouplers with industry-leading performance and reliability. This series of optocouplers provides isolation for various applications including power supply, motor control and data communications interface circuits. The primary functions optocouplers serve are signal isolation, noise elimination, and level conversion. NEC high speed optocouplers feature guaranteed CMR as high as 15 kV/µsec, output quiescent current as low as 3 mA, operating temperature to 100° C, speeds to 25 Mbps, and typical propagation delay as low as 20 ns. A unique series of NEC’s 15 Mbs optocouplers is the first to offer dual 3.0 / 5.5 Volt operation. These single and dual channel devices provide the flexibility of a low voltage part that can continue to deliver characteristic specifications as the power supply range of the design increases. Engineers tasked with miniaturizing their designs will also appreciate the variety of package styles NEC offers. From the low profile SOP-5 to the single and dual channel SO8, NEC packaging is designed to address engineers’ space constraints. Manufacturing is done in NEC’s production facility in Japan where all processes from initial wafer fabrication to final QA and package marking are fully automated. This allows for higher production rates and lower manufacturing costs, while assuring the superior quality and consistency you’ve come to expect from NEC. NEC optocouplers comply with worldwide safety standards.

The standard supports 32 drivers and receivers in a 2- or 4-wire differential configuration with cable lengths up to 4000 feet. Galvanic isolation becomes critical in the prevention of ground loops, electrical noise, and power spikes in widely distributed systems.

It delivers 13W of power over existing Ethernet cabling in various applications ranging from industrial IT to home office networks. To ensure safety for the end user, the 802.3af standard requires 1500 V AC of galvanic isolation between the main switch circuitry and the Media Dependent Interface (RJ-45 terminal). The communication from the switch to the PSE chip occurs over an isolated I2C bus.
