SN75LBC771DWG4 is a bus transceiver integrated circuit produced by Texas Instruments. This chip is designed for applications that require multiple drivers and receivers on a single bus line. The SN75LBC771DWG4 is part of the family of transceivers and receivers known as "BC" and belongs to the SN7LBC771 series. This series of transceivers was designed to provide a high degree of flexibility while maintaining good performance.
The SN75LBC771DWG4 measures only 5.2mm x 5.2mm and is capable of transmitting and receiving data at speeds up to 8 Mbps. This chip includes an integrated high-frequency (2.11GHz) crystal oscillator and a 3V regulator, eliminating the need for external components. It features an I/O contention and arbitration system, which can detect and correct data contention on the bus line. Additionally, this chip contains adjustable hysteresis and a programmable slew rate for optimal noise suppression.
Applications
The SN75LBC771DWG4 is frequently used as an interface for digital communication on printed circuit boards. It offers an ideal solution for applications such as Ethernet, USB, and serial communication links. Additionally, this chip can be used in systems with multiple clocks, making it a good choice for applications like global positioning systems (GPS) and other time-sensitive applications.
It is also used in medical, automotive and industrial automation applications. The SN75LBC771DWG4 is often used as an interface between multiple devices and a microcontroller, making it ideal for smart home applications.
Working Principle
The SN75LBC771DWG4 is an interface that allows data to be transferred between two or more devices. It is composed of a bus transceiver and two full-duplex operating modes, meaning that it can transmit and receive data simultaneously. It contains two I/O ports that enable connection to the bus line and it works by silently evaluating the state of the bus line and deciding when to transmit information.
When transmitting, the data is first latched into the internal shift registers. The data is then transmitted on the bus line, and the SN75LBC771DWG4 monitors the line for collisions. If a collision is detected, the chip will suspend transmission until the collision dissipates. This chip has two receive modes: one full-duplex and one half-duplex. When receiving, the data is first saved in the internal shift registers and then transferred to the register. It also contains programmable hysteresis and slew rate settings for optimal noise suppression.
