Unit in mm
The Toshiba TLP108 consists of a GaAAs light emitting diode optically coupled to a high-gain, high-speed photodetector. The TLP108 is housed in a 6-pin MFSOP. With a totem-pole output, the TLP108 is capable of both sinking and sourcing current. The TLP108 has an internal Faraday shield, which provides a guaranteed common-mode transient immunity of 10 kV/s. The TLP108 has an inverting output. A noninverting-output version, the TLP105, is also available. Inverter logic type (totem-pole output) Guaranteed Performance Over temperature: -40 to 100C Power Supply Voltage: 4.5 to 20 V Input Threshold Current: IFHL =1.6 mA (max) Switching Time (tpLH/tpHL): 250 ns (max) Common mode transient immunity: 10 kV/s Isolation Voltage: 3750 Vrms JEDEC TOSHIBA 11-4C2 Weight: 0.09 g (typ.)

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc). Note 1: Pulse width 1s, 300pps. Note 2: Pulse width 5s, duty cycle 0.025 Note 3: Device considered a two terminal device: pins 1 and 3 shorted together and pins 4, 5 and 6 shorted together.
