Düsseldorf, Germany: Toshiba Electronics Europe added three high-speed, low-power devices—packaged in mini SO6s—to its family of extended temperature IC optocouplers. Delivering data-transfer rates of up to 20Mbps, the new devices guarantee operation at a temperature range of -40°C to 125°C.

The TLP2362, TLP2366 and TLP2368 logic optocouplers will find homes in high-speed communication interfaces for factory-automation applications, industrial control systems, and measurement equipment. The ICs feature single inverter logic outputs and compliance with reinforced insulation requirements for EN60747-5-2 and other international safety standards.

Support for power-supply voltages of between 2.7 and 5.5V ensures compatibility with existing and new designs, as well as provides a migration path to lower voltage operation.

Both the 10Mbps TLP2362 and the 20Mbps TLP2368 have open collector outputs, while the 20Mbps TLP2366 possesses a totem-pole output, which enables both sink and source drives. Minimum isolation voltage for all three products is 3750VRMS; each is guaranteed for creepage and clearance distances in excess of 5mm.

Similar to the other family members, the TLP2362, TLP2366, and TLP2368 are built around GaAlAs LEDs that are optically coupled to high-gain, high-speed photodetectors. All offer very high input-to-output noise resistance, while internal Faraday shields ensure minimum common-mode transient immunity of ±20kV/μs.
