• Response Time (tPLH / tPHL): 4 μs (max)
• Operating Temperature Range: -55°C to +110°C
• Package Type: SOP-4 (Small Outline Package, 4-pin)

Descriptions:

• The TLP732GB is a phototransistor output photocoupler designed for high-speed signal transmission while maintaining high isolation voltage.
• It consists of a GaAs infrared LED optically coupled to a phototransistor in a compact SOP-4 package.
• Suitable for noise immunity, signal isolation, and voltage level shifting in digital and analog circuits.

Features:

• High isolation voltage (5000 Vrms) for safety and noise reduction.
• Fast response time (4 μs max) for high-speed signal transmission.
• Compact SOP-4 package for space-saving PCB designs.
• Wide operating temperature range (-55°C to +110°C) for industrial applications.
• High current transfer ratio (CTR) for efficient signal coupling.

This optocoupler is commonly used in power supplies, industrial controls, communication interfaces, and digital logic isolation.
