TLP105

TLP105 TOSHIBA PHOTOCOUPLER GaAℓAs IRED & PHOTO-IC TLP105 Isolated bus drivers High-speed line receivers Microprocessor system interfaces Unit in mm The Toshiba TLP105 consists of a GaAℓAs light emitting diode optically coupled to a high-gain, high-speed photodetector. The TLP105 is housed in a 6-pin MFSOP. With a totem-pole output, the TLP105 is capable of both sinking and sourcing current. The TLP105 has an internal Faraday shield, which provides a guaranteed common-mode transient immunity of ±10 kV/μs. The TLP105 has a noninverting output. An inverting-output version, the TLP108, is also available. JEDEC ― TOSHIBA 11-4C2 Weight: 0.09 g (typ.)

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 ≤ 1μs, 300pps. Note 2: Pulse width ≤ 5 μs, 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. 2 2008-08-27 TLP105 Electrical Characteristics (Unless otherwise specified, Ta = -40 to 100°C, VCC = 4.5 to 20 V) CHARACTERISTIC Input Forward Voltage Temperature Coefficient of Forward Voltage Input Reverse Current Input Capacitance Logic Low Output Voltage Logic High Output Voltage SYMBOL VF ΔVF/ΔTa IR CT VOL VOH TEST CIRCUIT CONDITION IF=10 mA , Ta=25°C IF=10 mA VR=5 V , Ta=25°C V=0 , f=1 MHz , Ta=25°C IOL=3.5 mA , VF=0.8 V IOH=-2.6 mA, VCC=4.5 V IF=5 mA VF=0 V VCC=20 V VCC=20 V VCC=5.5 V VCC=20 V VCC=5.5 V VCC=VO=5.5 V VCC=VO=20 V VCC=5.5 V VCC=20 V MIN. 1.45 TYP. 1.57 -2.0 MAX. 1.75 UNIT V mV/°C μA pF V V ― ― ― ― 1 2 ― ― ― ― 2.7 17.4 ― 10 0.6 ― 100 0.2 4.0 19.0 ― ― 3.0 3.0 3.0 3.0 Logic Low Supply Current ICCL 3 ― ― ― ― 15 20 -5 -10 ― ― ― ― 80 90 -15 -20 0.4 mA Logic High Supply Current Logic Low Short Circuit Output Current (Note4) ICCH IOSL IOSH IFLH VFHL IHYS 4 IF=5 mA VF=0 V IF=5 mA VO=GND mA 5 ― ― ― ― 1.6 mA Logic High Short Circuit Output Current (Note4) 6 mA Input Current Logic High Output Input Voltage Logic Low Output Input Current Hysteresis ― ― ― IO=-2.6 mA,VO>2.4 V IO=3.5 mA,VO
