74VCXH162244MTD is a 64-channel differential signal buffer and transceiver consisting of 16 channels of 4-bit-wide signal carrying capability. It has both an input buffer and output driver in one package, making it an ideal choice for cost and space efficient logic signal buffering and signal multiplexing. As a logic device, it is classified as a buffer, driver, receiver or transceiver.

Application Field

In many applications, drivers and receivers are used to send either analog or digital signals over long distances, ensuring signal integrity and maintaining signal quality. Long transmission lines, such as coaxial cables, often require signal buffering to suit the application\'s requirements. The 74VCXH162244MTD works well in situations calling for long-distance signal transmission, as its low power dissipation per differential buffered signal ensures signal quality throughout the entire distributed system.

In addition, the device features an active-high enable and an active-low active-low disable for each channel, which makes it suitable for applications that require multiplexing different signal types over a single wire. Furthermore, remote sensors, touchscreens and smart meters also benefit from using this device, as it helps achieve low-voltage, low-power operation.

Working Principle

The primary purpose of the 74VCXH162244MTD is to perform signal buffering and multiplexing functions. As such, it has an input buffer to drive either an analog or digital signal over long distances and a corresponding output driver. Input and output pins are designed in an opposite-driving mode which serves to cancel out the parasitic capacitance of the external transmission line.

When the output driver is active, the transmitting device can transmit either analog or digital signals. The device also features level-shifting, which allows it to provide high-immunity against noise. This means that even in high-noise environments, such as near high-powered motors, the device is able to deliver an accurate signal without impairment.

The 74VCXH162244MTD consumes low power and provides reliable signal transmission over long-distance links. This makes it ideal for a wide range of applications, from high-frequency serial communication to digital bus bridging, data transmission, and remote sensing applications.
