Overview
The M74HC4851YTTR is a single 8-channel analog multiplexer/demultiplexer manufactured by STMicroelectronics. It is produced using silicon gate C2MOS technology, which ensures low power dissipation and high performance. This device is particularly suited for automotive applications due to its injection current effect control, allowing signals at disabled input channels to exceed the supply voltage range without affecting the enabled analog channel.
