The OPI1264C is an Opto Isolator manufactured by TT Electronics. It contains an LED and a phototransistor in a single package, providing electrical isolation between input and output circuits. Opto-isolators are used to prevent ground loops, protect sensitive circuits from high voltages, and isolate noisy circuits from clean ones.

Applications

• Industrial Control Systems: Isolating control signals from high-power equipment.
• Power Supplies: Providing isolation between the primary and secondary sides of a power supply.
• Medical Equipment: Isolating patient-connected circuits for safety.
• Motor Control: Isolating control signals from motor drive circuits.
• Data Communication: Providing isolation in communication interfaces such as RS-232 and RS-485.

Features

• Electrical Isolation: Provides high voltage isolation between input and output.
• High Current Transfer Ratio (CTR): Efficiently transfers current from the LED to the phototransistor.
• Fast Switching Speed: Suitable for applications requiring fast signal transmission.
• Compact Package: Small package size for space-saving installation.
• Through-Hole Mounting: Designed for through-hole mounting on printed circuit boards.

Benefits

• Ground Loop Prevention: Eliminates ground loops, reducing noise and improving signal integrity.
• High Voltage Protection: Protects sensitive circuits from high voltages.
• Safety Isolation: Provides electrical isolation for safety in medical and industrial applications.
• Noise Reduction: Isolates noisy circuits from clean circuits, reducing interference.
