2. General
The Toshiba TLP2745 consists of high-output GaAℓAs light-emitting diode coupled with a high-gain, high-speed
photo detector. It is housed in a thin SO6L package of 2.3 mm (max). The TLP2745 has guaranteed the isolation
voltage 5 kVrms and compliant with international safety standards for reinforced insulation. This product can
operate in power supply voltage 4.5 V to 30 V with the maximum operative temperature of 110 . Since TLP2745
has guaranteed 3 mA low supply current (ICCL/ICCH), and 1.6 mA low threshold input current(IFLH), it contributes
to energy saving of devices. It can drive directly from a microcomputer for a low input current. The detector has
a totem-pole output stage with current sourcing and sinking capabilities. The TLP2745 has an internal Faraday
shield that provides a guaranteed common-mode transient immunity of ±30 kV/µs. The TLP2745 has a buffer
output. An inverter output version, the TLP2748, is also available.
