• High-speed logic interface
• Programmable controllers (PLCs)
• Inverter control
• Measurement equipment
• Office automation equipment

Features

• High-speed operation: 10 Mbps (typ.)
• Guaranteed performance from temperature: -40 to 100°C
• Low input current: IF = 5 mA (max.)
• Supply voltage: 3 to 5.5 V
• Common-mode transient immunity: ±20 kV/μs (typ.)
• Creepage distance: 8.0 mm (min.)
• Clearance: 8.0 mm (min.)
• Insulation thickness: 0.4 mm (min.)

Benefits

• Enables high-speed digital signal transmission.
• Provides reliable operation in harsh industrial environments due to wide operating temperature range.
• Reduces power consumption due to low input current requirement.
• Offers high noise immunity due to high common-mode transient immunity.
• Provides enhanced safety due to high creepage distance, clearance, and insulation thickness.

Additional Details

The TLP665G is available in an SO6 package. It is compliant with international safety standards such as UL, cUL, and VDE. The internal insulation thickness is 0.4 mm minimum, offering reinforced insulation. The isolation voltage is 5000 Vrms. The propagation delay time is typically 7 ns, and the propagation delay skew is typically 4 ns. This photocoupler is suitable for applications where high speed, high reliability, and safety isolation are critical.
