Toshiba Announces Space-Saving Dual Channel IC-Couplers

Surface Mount Optocouplers in S08 Packages Reduce Board Area by 40 Percent Compared to Single-Channel Devices

IRVINE, Calif., April 8 /PRNewswire/ -- Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, has expanded its IC photocoupler lineup with three dual-channel, totem-pole output devices housed in low profile S08 packages. Each of these devices, developed by Toshiba Corp. (Toshiba), reduce board area by approximately 40 percent per channel compared to single-channel devices in MFSOP6 packages to help reduce size and cost of multi-channel applications.

Two 5Mbps devices include the TLP2105, with buffer logic output, and the TLP2108, with inverter logic output. Applications for these photocouplers include insulated bus drivers, high speed line receivers, and system interfaces for microprocessors.

The 15Mbps TLP2166A features inverter logic output and a supply voltage of 3.3V, making it suitable for high speed, low-voltage applications such as interfaces for digital measurement and control equipment, insulated PC boards and various communication protocols.
