Introduction

Optoisolators are an integral component in electronic systems to prevent the spread of disturbances between groups of circuits with different electrical potentials. An optoisolator such as the HCPL-263L#300 is specifically built for logic output applications. It offers 2000 Volts of galvanic isolation, detecting a low voltage logic signal up to 12V, and converting it into a portable and calibrated CMOS or TTL logic output level.

Description

The HCPL-263L#300 is a compact logic output optoisolator package designed specifically for optoelectronic isolation applications. The device consists of a precision 8-pin dual-in-line (DIP) package with an internal optical isolator. It detects logic-level input of either 5V or 12V and delivers a logic-level regulated output of either TTL/CMOS logic. The HCPL-263L#300 features device operating temperature range of -40º to +85º C allowing for a wide range of usage. The HCPL-263L#300 provides excellent isolation with 2000 Volts of galvanic isolation and 3000V of surge isolation. It also offers a control current ranging from 0-3.5mA and logic frequency of 6MHz, sufficient for a wide range of logic-level opto-isolation applications.

Working Principle

The HCPL-263L#300 optoisolator works by transferring a low voltage logic signal across an optically isolated barrier, preventing the spread of electrical disturbances. The transmission is done by light, and the logic signal is converted into an equivalent logic-level output. The device achieves the logic transfer with a single monolithic system comprised of an infrared emitter, an integrated phototransistor detector, an amplifier and thin film resistors on a single chip.The output is typically a TTL or CMOS logic level output of either 5 or 12 Volts, depending on the specific input received. The device is designed with fast edge response on the input side and well-damped circuit topology on the output side.

Applications

Due to its high isolation rating, fast switching speed, and logic-level output the HCPL-263L#300 is used in a wide range of applications. The optoisolator is primarily used in logic circuits where isolation between two logic or microcontroller systems is desired. HCPL-263L#300 is also used in industrial, communications, consumer electronics, instrumentation, motors and automotive systems.The device is also suitable in applications that require surge protection, such as power supplies and UPS’s. With its tight package the HCPL-263L#300 can be used in circuits with stringent space constraints.

Conclusion

The HCPL-263L#300 is a fast switching, logic-level output opto-isolator that offers 2000 Volts of galvanic isolation and 3000V of surge protection. The device achieves fast edge response and precise logic transfer with no external components, providing an efficient and low-cost solution for isolation of logic circuits. The device is used in a wide range of applications including industrial, communications, consumer electronics, instrumentation, motors and automotive systems.
