• Signal transmission or signal reception in RS 232/422/485 Ethernet systems, or with other similar communication protocols.

Working Principle

TLP2355(E) is based on a phototriac technology whereby a semiconductor device, a phototriac, employs three separate components: a semiconductor, a light emitting diode (LED) and an optically coupled photodiode. The optically coupled photodiode is triggered by the LED to emit an electrical signal that is then amplified and sent to the output. In addition, the optically coupled photodiode prevents the LED from being affected by external interference.

The TLP2355(E) isolator is a dual output optoisolator that utilizes a light emitting diode (LED) to receive input signals, an optically coupled photodiode to process and transmit output signals, and, special shielding technology to minimize noise. This optoisolator provides superior noise immunity and fast response time, making it suitable for a wide variety of applications. It is also capable of handling high power, making it an ideal solution for AC and DC switching applications.

The TLP2355(E) is designed to be compatible with various industrial standard signal types and offers both single-channel and four-channel output configurations. The device is available in various packages, including SOT89, DIP, SOIC, and cased-cavity-through-hole. The device can also be configured to provide high speed switching and response time between 10 ns and 80 ns.

Conclusion

The TLP2355(E) optoisolator is a logic-output type of optoisolator designed to provide superior noise immunity and high-speed response time for AC and DC switching applications, signal transmission and signal reception. This device is also suitable for efficient heat dissipation applications, such as heating and is available in a 4-channel/1-channel dual-output configuration that is compatible with various industrial standard signal types.
