74LCXZ16244MTD Application Field and Working Principle

The 74LCXZ16244MTD is a transceiver that combines the properties of a buffer, driver and receiver in one integrated package - a single-width, 4-bit buffer/driver/receiver. It is designed to be used in digital logic circuits, such as those involving data transfer and data interfacing. It provides the flexibility and power required for handling data paths.

Application Field

The 74LCXZ16244MTD transceiver can be used for a wide range of applications, such as:

• Data path buffering and interfacing
• Digital signal transfer from one device to another
• Data transfer between two devices
• Data interfacing between two devices

In addition, the transceiver can be used for a variety of other applications including:

• High speed data multiplexers
• Asynchronous transfer mode controllers
• Field programmable gate array (FPGA) programming and configuration
• Digital signal processor (DSP) connections
• Gigabit Ethernet and other digital communication systems
• High speed bus interfaces

Working Principle

The 74LCXZ16244MTD transceiver consists of two 4-bit buffers/drivers and two 4-bit receivers. The device features differential data inputs and outputs, as well as complementary data (inverted) inputs and outputs. The transceiver is designed to operate at a maximum frequency of 33MHz. It operates at a voltage range of 3.3V, 5V and 12V, and is able to drive both the outputs of the two 4-bit drivers and the inputs of the two 4-bit receivers.

The two 4-bit buffer/drivers present a 4-bit data input at the logic levels of the powered supply, whereas the receiver inputs operate from the logic levels of the powered supply. The transceiver can be configured in three different modes: 1) Normal Mode – all outputs of the 4-bit drivers are enabled; 2) Tri-State Mode – some outputs of the 4-bit drivers can be disabled; and 3) High-Z Mode – all outputs of the 4-bit drivers are put in a high impedance state. This allows for a wide range of applications to be implemented with the device.

The two 4-bit receivers present a differential output in order to reject any noise present at the receiver inputs. This differential output provides an interface to all kinds of digital logic circuits, including microprocessors, analog to digital converters and latched logic. The differential output is also designed to provide a lower power dissipations than traditional 4-bit-per-byte drivers.

Conclusion

The 74LCXZ16244MTD is a versatile transceiver that combines the properties of a buffer, driver and receiver in one integrated package. It can be used for a wide range of applications including FPGA programming, data path buffering and interfacing, digital signal transfer, data interfacing and more. The device’s ability to be configured in three different modes (normal, tri-state and high-Z) provides it with the flexibility to handle a variety of data paths. Additionally, its differential output allows for a lower power dissipation than traditional 4-bit-per-byte drivers.
