The SN74LVTH16500DLR is a universal bus function that drives and changes its characteristics depending on its application in different scenarios. It is an asynchronous dual port register having an output rate of 18 MB/s. Since it is unidirectional, data cannot be transferred between two ports of the same register. This makes the register ideal for applications where data transmitted on one port is isolated from the other. Additionally, the internal states of this register are maintained when power to the system is disabled to the register. Due to the internal state-holding functionality, direct logic integration with logic elements of the system is facilitated. Moreover, the register can be operated in multiple modes so as to guarantee a variable drive strength and glitch-free output.

The SN74LVTH16500DLR acts as a buffer between two existing buses in a data transfer system. It has a data input port and a data output port dedicated to each bus. The data received on one port is buffered and forwarded to the other port in order to permit asynchronous transfers. This register can accept up to eight bits of data at a time and can deliver a maximum of 18 million bits per second. An internal clock offers flexibility when it comes to the frequency of data transmission.

The SN74LVTH16500DLR has two operating modes; self-timed and externally timed modes. In the self-timed mode, the internal clock sets the speed of the data transfer. On the other hand, in the external timed mode, clocking signals from other sources control the transfer rate. In the latter mode, synchronization is required between the clock source and the register in order to ensure successful transmission.

The SN74LVTH16500DLR also provides active drive capability which gives a high value of noise performance when the data is being transferred between multiple devices. Additionally, it has two different output strengths for a faster data rate or better noise performance. A low output drive is provided for low voltage operations and a high output drive is provided for improved noise performance. The SN74LVTH16500DLR can be used to interface two independent system buses allowing for faster data transfer.

The SN74LVTH16500DLR is quite versatile and can be used in a variety of applications including handshaking and data arbitration in digital systems, bridging two different buses, storing data and outputting variables. This register is a cost effective alternative to conventional bus functions and can be used in applications that require speed, bus isolation, energy saving, low noise and active drive capability, with minimal impact on performance.
