TLP2391
1. Applications
• Programmable Logic Controllers (PLCs)
• Industrial Inverters
• High-Speed Digital Interfacing for Instrumentation and Control Devices
2. General
The Toshiba TLP2391 consists of two high-output infurared LED coupled with a high-gain, high-speed photo
detector. It is housed in the SO6 package.
Since it is making two LED reverse parallel, it can be dealt with both sinking and sourcing input signals.
Since TLP2391 has guaranteed 1 mA low supply current (ICCL/ICCH), and 2.5 mA (VCC = 5 V) low threshold input
current(IFHL), it contributes to energy saving of devices.
The detector has a totem-pole output stage with current sourcing and sinking capabilities. The TLP2391 has an
internal Faraday shield that provides a guaranteed common-mode transient immunity of ±20 kV/µs.
