Overview
Photocouplers GaAℓAs Infrared LED & Photo IC TLP2408 TLP2408 1.
Applications • 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.
