The LE75181BBSC is an integrated circuit containing two independent differential-signal line drivers. It is used primarily in point-to-point and multi-point communications, such as those used in X.21 and T1/E1 applications. It is also suitable for applications that require high-speed serial data communications, such as high-speed modems. This article discusses the application fields and working principle of the LE75181BBSC.

Application Fields
The LE75181BBSC is a building block unit providing a low-power line driver with a low differential output impedance and very low propagation delay. This IC is suitable for X.21 and T1/E1 applications, where it transmits digital signals over an available twisted-pair wire or coaxial cable. It is also suitable for high-speed modems, where it provides full-duplex data transmission for both low- and high-speed modems. In addition, this IC is applicable in optical-fiber communication systems, where it is used as the interface between the optical fiber and the digital circuitry.

Working Principle
The LE75181BBSC integrated circuit is based on three major components: a differential-signal line driver, a low-power output buffer, and a timing generator. The differential-signal line driver receives an input signal, amplifies it and then transmits it across a twisted-pair wire or coaxial cable. The low-power output buffer buffers the output signal and isolates it from the input signal. It also provides protection against transient voltage spikes. The timing generator controls the output buffer, ensuring correct timing of its operations. This allows the LE75181BBSC to accurately transmit its output signals from the point a to point b.

The LE75181BBSC integrates a direct current feedback differential amplifier, allowing it to accurately transmit digital signals over long distances without errors. Furthermore, the low-power output buffer ensures that the information is transmitted efficiently and without losses. The LE75181BBSC operates on a nominal supply voltage of 5.0V and draws a maximum current of 10mA.

In summary, the LE75181BBSC is an integrated circuit containing two independent differential-signal line drivers. It is used primarily in point-to-point and multi-point communications, such as those used in X.21 and T1/E1 applications, or for high-speed modems. It is based on a differential-signal line driver, a low-power output buffer and a timing generator, and operates on a nominal supply voltage of 5.0V, drawing a maximum current of 10mA. This IC is suitable for long-distance data transmission, is reliable and efficient, and requires minimal power consumption.
