• High-Speed Digital Interfacing for Instrumentation and Control Devices
• Communications Equipment
• Intelligent Power Module Signal Isolation
2. General
The Toshiba TLP2408 consists of a GaAℓAs light-emitting diode coupled with a high-gain, high-speed photo
detector. It is housed in the 8-pin SO8 package. The detector has a totem-pole output stage with current sourcing
and sinking capabilities. The TLP2408 has an internal Faraday shield that provides a guaranteed common-mode
transient immunity of 15 kV/µs.
The TLP2408 has a logic inverter output. A buffer output version, the TLP2405, is also available.
