TCDT1120

TCDT 1120 optoisolators are a type of transistor, photovoltaic output optoisolator that is isolated from the input, providing direct current reversing and interfacing applications. In operation, they connect an optically-isolated device to a driving computer, I/O module, or a microcontroller. This device limits damage to the driver components by isolating the input, while still allowing signal transmission.

TCDT 1120 optoisolators work by combining light emitting diodes (LEDs) and photodiodes. The LEDs send an output beam of light that is then received by the photodiodes, inducing a voltage and current flow. This optical isolation makes it possible to have control logic systems that are immune from any potential EMI radiation or ground spikes. It also allows for the signal to be received without experiencing any interference from other components or wiring.

The TCDT 1120 optoisolator enables designers to expand sequential and parallel logic applications, 5V TTL and CMOS logic, as well as microcontroller signals. It offers a wide range of features that enable system designers to leverage a fast channel response, damping capability, and 100 kHz of transmission speed. For systems that need to move data between AC and DC circuits, this device also offers optoisolation current transfer from 20mA to 300mA.

The TCDT 1120 optoisolator also provides reliable signal transmission and isolation between a transmitter and a receiver. It has the ability to transmit signals up to 100kHz, providing an immunity of up to 500V breakdown voltage. The device also has low input capacitance and low contour resistance, which provides excellent noise performance. The optoisolation reduces ground loops, high voltage stress, and unpredictable input levels.

The TCDT 1120 optoisolator is ideal for designs that need to transfer a signal from one circuit to another without affecting the signal. It offers many advantages, such as immunity to EMI radiation, elimination of ground loops, and noise immunity. It can be used to protect sensitive signals from ground noise, high voltages, and interference. The integrated photodetector also provides reliable signal transmission up to 100 kHz, which makes it a powerful device for controlling logic systems.

The TCDT 1120 optoisolator is a great choice for designers who need to securely transfer data and signals between different points in a system. It provides high performance, low power consumption, and reliable transmission. The device can be used for both AC and DC circuits, and can be used for signal transfer from 20 mA to 300 mA. The optoisolation also minimizes ground loops, high voltage stress, and unpredictable input levels, making it an ideal solution for applications that require fast and reliable signal transfer.
