The CD74HC4351ME4 is a quad, 2-to-1 multiplexer with TTL compatible logic levels. It is part of the high-speed CMOS logic family of devices. The device operates from a single 5-V supply and is available in a 16-pin Lloyd package. The device is typically used to select one of two digital signals for applications such as communications, data acquisition, and control.

The application field of the CD74HC4351ME4 mainly lies in the areas of communication, data acquisition, and control. It can be used in data acquisition systems to selectively enable or disable analog devices, in control systems to direct signals to one out of multiple sources, and in communications systems to enable or disable signals on a bus. The device is also used as a switch for switching signals between multiple signal sources.

The CD74HC4351ME4 has two control channels with TTL-compatible logic levels that enable and disable the signal paths controlled by the multiplexer. The multiplexer has four signal channels and each signal channel can be enable and disabled independently. The device also has open-drain outputs that enable the user to extend the signal path.

The working principle of the CD74HC4351ME4 is that it receives an enable signal on one of its two control channels and based on this enable signal it will open or close the signal paths connected to its four signal channels. Depending on the enable signal, one of the signal channels will be enabled and the others will be disabled. The device uses TTL logic levels to control the signal paths and the enable signal must be a logic level 1 to enable one of the signal channels.

The CD74HC4351ME4 is a high-speed CMOS logic device and is capable of operation at up to 5MHz. The device has a guaranteed 2V to 6V operating voltage range and a passive pull-up resistor is included on each of the output channels. The device also features power-on reset which allows the user to reset the device without disconnecting the power source.

The CD74HC4351ME4 is a versatile and reliable quad, 2-to-1 multiplexer with TTL compatible logic levels that can be used in a variety of applications. It has four signal channels that can be enabled or disabled independently and its open-drain outputs allow the user to extend the signal path. The device is capable of operating at up to 5MHz and its power-on reset feature allows it to be reset without the necessity of disconnecting the power source. The CD74HC4351ME4 is a ideal device for applications such as communications, data acquisition, and control.
