Dual-channel photocouplers save 40% board space

Toshiba America Electronic Components Inc. has broadened 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., reduce board area by approximately 40 percent per channel compared to single-channel devices in MFSOP6 packages to help reduce size and cost of multichannel applications.

Two 5Mbit/s 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 15Mbit/s 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.

All three devices operate at a -40°C to 100°C temperature range. Samples of the Toshiba dual-channel photocouplers are available now. Prices for the 5Mbit/s TLP2105 and TLP2108 are $1.72 in quantities of 100. The TLP2166A is priced at $2 each in quantities of 100.
