Digital high speed photocoupler in miniature package

Toshiba’s new TLP117 photocoupler integrates a high-speed GaAlAs infrared LED and a high-gain, high-speed photodetector within a surface mount MFSOP6 package that measures just 4.4mm x 3.6mm x 2.5mm. Maximum propagation delay is as low as 20ns, leading to typical switching speeds of 50Mbps (NRZ).

The TLP117 photocoupler is ideal for applications requiring a combination of isolation, high speed data transfer and low power operation. Target applications will include logic systems in plasma panel displays (PDPs) and other digital home appliances, and high speed interfaces in modern factory automation systems.

Operating with a nominal power supply voltage of 5V, the TLP117 has a maximum current consumption of under 5mA. The photocoupler is configured in an inverter logic (totempole output) format and provides an isolation voltage rated at 3750Vrms. An internal shield ensures a minimum common mode transient immunity of 10kV/µs (min).

Designed to comply with all international safety approvals, the TLP117 offers guaranteed performance at temperatures ranging from -40ºC to 105ºC.
