M75179P芯片反向设计与IC解密

深圳鹏芯集成电路在IC解密研究中成功破解了M75179P典型芯片型号，针对该芯片，我们解密周期短、价格低、可靠性强。这里，我们将针对M75179P芯片的主要技术特征做简单介绍，供大家参考借鉴。
DESCRIPTION OF FUNCTION
The M75176P to M75179P are line interface ICs which meet EIA standards RS-422A and RS-485, and are suitable for long-distance, high-speed data transmission.The M75176P is designed to connect the driver circuit output and the receiver input to each other internally,and serves as a line transceiver. The M75177P/M75178P is designed to connect the receiver circuit output and the driver circuit input internally,and serves as a line repeater.The M75177P and M75178P enter the output enabled state with active"H"and active"L", respectively. The M75179P is equipped with a built-in differential driver and a built-in differential receiver.It does not have an output control input pin but its output impedance at the power-OFF time goes high.
FEATURES
