Working Principle of SN74ALVTH16240VR

The SN74ALVTH16240VR is a noninverting 8-channel multiplexer/memory register with tri-state outputs comprising two independent buffers. Each channel has an active high enable input, a data selector input and a data buffer input. The device is organized as a memory register, in which data can be loaded and stored, and the output is buffered. The output enable signal (OE) controls the tri-state outputs and prevents the data from changing state when the power is off.

Each buffer is composed of a set of eight NAND gates, four data selectors, and four data buffers, all controlled by an enable (E) signal. When the enable signal is activated, the data selector gates select one of the four data inputs and forward it to the output. When the enable signal is disabled, the output is held in a high impedance state, allowing multiple buffers to share an output line without interference.

The SN74ALVTH16240VR is capable of operating at very high speeds in both data loading and data retrieval modes with minimal power consumption. In addition, the device is also equipped with two outputs enable pins (OE1 and OE2), which allow users to control the tri-state outputs independently. The device has low propagation delay and low power consumption, making it suitable for high-performance applications.

Conclusion

The SN74ALVTH16240VR from Texas Instruments Inc. is a versatile and powerful device used for multiple applications such as data bus multiplexing and demultiplexing, zip drive serial interface, Ethernet line termination, memory logic elements, low-voltage to high-voltage translation, signal switching systems, and many more. The device comprises two independent buffers that are composed of a set of eight NAND gates, four data selectors, and four data buffers, all controlled by an enable (E) signal. With its low power consumption and high performance, the SN74ALVTH16240VR is an ideal choice for many applications.
