The SN75LBC776DBR is a wide voltage range supply integrated circuit from Texas Instruments. This type of IC is specially designed for applications like DSL modems, cable modems and other telecommunication applications in the field of electrical engineering.

It belongs to the interface - drivers, receivers, transceivers category. This type of IC basically controls the transmission of digital signals across various types of media. The SN75LBC776DBR offers the user a wide voltage range of 1.4V-4.7V and its peak output current is 6mA. It also features a separate enable pin which allows further system protection by preventing unexpected inputs.

The SN75LBC776DBR contains two independent driver/receiver channels with integrated ESD protection. Each channel is built up of a quad differential line driver and a quad single-ended line receiver. It also offers an operating frequency range of up to 150MHz which can be used for harsh environment applications. The receiver side of the IC features adaptive hysteresis which improves signal integrity.

The working principle of the SN75LBC776DBR is similar to other types of transceiver ICs. The line driver part of the transceiver converts the input logic level into a regulated signal level according to the type of standard being used. For example, if the signal being transmitted is differential, the driver will convert it into a differential signal. Then, the receiver side of the IC takes the converted signal and converts it back into the input logic level.

The SN75LBC776DBR is widely used in different applications such as DSL modems, cable modems, FTTx equipment and other telecom applications. It offers a very high speed range, has low power dissipation and provides a high degree of system protection against unexpected inputs.

In summary, the SN75LBC776DBR is an interface-driver, receiver and transceiver IC from Texas Instruments. It offers a wide voltage range and high speed range and is widely used in telecommunications applications. It has low power dissipation and provides system protection from unexpected inputs by using a separate enable pin. The working principle of the IC is that it converts the logic level inputs into regulated signal levels and also converts the output signal back into its original logic level.
