The Toshiba TLP2105 consists of GaAℓAs light emitting diodes and integrated high gain, high-speed photodetectors. The TLP2105 is housed in the 8-pin SO package.
The photodetector has totem-pole output stage that can source and sink current.
The photodetector has an internal Faraday shield that provides a guaranteed common-mode transient immunity of ±10 kV/μs.
The TLP2105 provides noninverting logic output. An inverting logic version, the TLP2108, is also available.

• Buffer logic output (totem-pole output)
• Guaranteed performance over -40 to 100°C
• Power supply voltage: 4.5 to 20 V
• Input threshold current: IFLH =1.6 mA(max)
• Switching time (tpLH / tpHL): 250 ns (max)
• Common mode transient immunity: ±10 kV/μs
• Isolation voltage: 2500 Vrms
