LTC4314IUDC#TRPBF

The LTC4314IUDC#TRPBF is an ultralow capacitance, bidirectional esd protection device for high speed data-lines including LVDS, RS-422, RS-485 and CML data transmission applications. It is widely used in interface applications, such as signal buffers, repeaters, splitters, and many other applications. This device provides two independent channels that protect against both ESD and EFT events with low capacitance on each line. The device features adjustable trip-point and can be easily inserted into the target system.

The LTC4314IUDC#TRPBF works by using an integrated resistor network to provide an adjustable trip point and to clamp voltages across the data-line. It is connected to two differential lines via 2KV high voltage protection diodes. The protection diodes limit the transient voltages which can be generated during ESD and EFT events. The output buffer is designed to switch off at user-adjustable thresholds, further protecting the circuit from voltage overshoots.

The LTC4314IUDC#TRPBF is well adapted for multi-gigabit applications. It offers low capacitance of 20pF ensures minimum crosstalk and maximum data integrity. It also allows operation from 3V to 5V linear supplies with a wide operating temperature range from -40C to 85C. Furthermore, the device has overvoltage protection circuitry that guards against voltage transients and overvoltage conditions. This yields up to 500mA of current at +/-24V and 400mA at +/-18V.

The LTC4314IUDC#TRPBF is also capable of protecting data lines up to 1000MHz, with low distortion and low propagation delay. It includes a built-in logic circuit that detects open circuits and shorts, enabling it to automatically disable the output in the event of a fault. In addition, the device features two additional pins to control the on/off states of the device. This makes it ideal for applications requiring the protection of multiple data lines.

In summary, the LTC4314IUDC#TRPBF is a highly efficient adjustable trip-point, low capacitance protection device for high speed data-lines. It is designed for interface applications, such as signal buffers, repeaters, splitters, and other applications. It offers low capacitance and overvoltage protection, with a wide operating temperature range and up to 500mA of current at +/-24V.
