Clock buffers, drivers, and other clock/timing-related products are essential components that ensure reliable video, data, and audio signals are distributed properly throughout a system. The 83905AG-01LF is a high-performance 8-bit voltage translator with low-skew output enable (OE) buffers. This device offers both non-inverting and inverting translation, allowing for interfaces with different logic families to be supported. It has a wide input and output voltage range from 1.2 to 3.6V and its outputs support 3.3V or lower logic levels.

The 83905AG-01LF device is designed for applications that need to transfer digital data between two logic families with different voltage ranges. This makes it suitable for use in FPGA and ASIC designs, as well as in board designs that require the interface of multiple power source ranges. It is also suitable for legacy boards, where it can bridge the gap between 5V and lower voltage.

The 83905AG-01LF device architecture comprises two LVCMOS buffers, each with two sets of four latches. These are used to control the output enable (OE) signals, which are then connected to each individual block translator. The translation between the input and output is determined by the signal level that is set on the OE for each block. The device also incorporates four input buffers for voltage translation between the two blocks.

The 83905AG-01LF device is controlled by the global signal OE, which determines the logic level on the OE for all four blocks. When this signal is set to Logic 0, all four blocks are disabled, and no translated output will be produced. When this signal is set to Logic 1, the designated OE signals for each block and the translation between the input and output will be provided.

The 83905AG-01LF device offers low-skew output enable buffers with adjustable current levels. This allows the user to ensure that timing requirements are met, and it also allows for additional flexibility in the design of the system.

In addition to its low-skew output enable buffers, the 83905AG-01LF device has adjustable voltage translation to allow the user to optimize the output voltage levels. The voltage translation feature is also beneficial in applications where the output voltage needs to be adjusted to match the input voltage levels.

The 83905AG-01LF device can be used in applications where high-speed data transfers between logic families and lower voltage levels are required. For example, it can be used for interface adapters, bus bridges, and data routers. The device can also be used in systems that require voltage level shifting due to differences in logic families, or for systems requiring precise timing on the output signals.

In summary, the 83905AG-01LF device is designed for transferring digital data between two logic families with different voltage ranges. It offers low-skew output enable buffers and adjustable voltage translation, making it an ideal solution for high-speed, low-voltage applications. Its adjustable current levels and pocket-size package make it well suited for legacy boards, FPGA and ASIC designs, and applications that require precise timing on the output signals.
