The LTV-824S is an optoisolator part from Lite-On Inc. It is part of the Optoisolators – Transistor, Photovoltaic Output family and is designed to provide electrical isolation between two circuits while transferring information between the two. The optoisolator separates the two circuits through the use of a photosensitive device coupled with a light-emitting diode (LED) and a transistor switch. The LTV-824S can switch up to 200mA at up to 35VDC, can be triggered with input currents as low as 1.0mA and can switch frequencies up to 100kHz. It offers an insulation resistance of up to 2200VRMS and a creepage distance of up to 9mm.

The optoisolator has a dual-in-line package (DIP) design and can handle ambient temperatures of -40° to +85°C. It is rated for the UL, CSA and VDE safety standards with a guaranteed voltage of up to 66V and a surge voltage of up to 200V. The LTV-824S also features a wide operating voltage range of 5-40VDC. It can be used in both switching and linear applications and is available in two versions—with and without a phototransistor output. The optoisolator also features a low power requirement and high noise immunity.

The LTV-824S optoisolator’s working principle is based on using light to electrically isolate two circuits. The chip contains a photosensitive device, an LED and a transistor switch. When there is no electrical current in the input circuit, the LED does not emit light and the transistor switch is in an open state. When current is applied to the input circuit, the LED is triggered to emit light which strikes the photosensitive device and closes the switch. This allows the output circuit to be activated or deactivated based on the electrical signal in the input circuit.

The LTV-824S optoisolator is widely used in industrial applications due to its high electrical isolation, isolation resistance, and wide operating voltage range. It can be used for applications such as power control, relay control, lighting control and I/O logic. Other applications include process control, electric motor control, safety interlocking, security system, SMPS control and line isolation.

Overall, the LTV-824S optoisolator from Lite-On Inc. is a highly efficient and durable component for electrical isolation and transfer of signals between two circuits. It provides a constant and reliable electrical isolation while offering excellent surge voltage and insulation resistance. The LTV-824S is available in two versions with and without a phototransistor output and can handle high operating temperatures and a wide operating voltage range. The optoisolator is widely used in industrial applications for applications such as power control, relay control, lighting control and I/O logic.
