Overview
The M74HC4851YRM13TR is a single 8-channel analog multiplexer/demultiplexer manufactured by STMicroelectronics using silicon gate C2MOS technology. This device is particularly suited for automotive applications due to its injection current effect control, which allows signals at disabled input channels to exceed the supply voltage range or go down to ground without affecting the signal of the enabled analog channel. This feature eliminates the need for external diode-resistor networks, making it highly efficient and reliable in various environments.
