Toshiba America Electronic Components Inc. has unleashed a high-speed photocoupler that provides protection against extreme operating temperatures. The TLP2768A can sustain data rates up to 20Mb/s, aimed at high-speed communication interfaces in factory automation systems, measurement and control equipment and plasma display panels.


The TLP2768A features an operating temperature range of -40°C to 125°C, enabling it to be used in increasingly compact industrial equipment that contains a greater density of components and therefore has higher internal temperatures. An open-collector output allows for both sink and source drive implementations. The TLP2768A supports both 3.3V and 5.5V power supplies, making it compatible with a wide range of existing industrial applications as well as ensuring it meets the needs of new and emerging low-voltage designs, stated Toshiba.

The TLP2768A high-speed photocoupler features a LED coupled with integrated high gain, high-speed photodetectors. It features an inverter-logic output and operates over an extended temperature range while complying with the reinforced isolation class requirements of international safety standards. Housed in Toshiba's ultra-thin S06L package, the TLP2768A offers a maximum height of just 2.3mm, which means a thickness reduction of approximately 45 per cent, yet achieves a very high minimum isolation voltage rating of 5kVrms. The S06L package is able to maintain creepage and clearance distances up to 8mm.

The TLP2768A photocouplers are available.
