Specialty Logic Procurement Notes

Verify the 'X' suffix indicates tape and reel packaging rather than trays. Confirm the component is sourced from Fairchild Semiconductor or its successor entities like onsemi. Ensure the datasheet revision matches the manufacturing date code for accurate electrical specifications.

Specialty Logic Selection Notes

Select this component for applications requiring dual 13-bit registers with SSTL-2 compatibility. Ensure the system voltage aligns with the 2.3V to 2.7V operating range. Verify that the differential clock requirements match the source driver capabilities and that the TSSOP package fits the PCB layout constraints.

Specialty Logic Part Context

This part belongs to the SSTV series of registered buffers designed for high-speed memory interfaces. It was originally manufactured by Fairchild Semiconductor and is now associated with onsemi. The device addresses the need for registered buffers in DDR memory modules to improve signal integrity and drive capability.

Specialty Logic Replacement Considerations

Direct substitutes include SN74SSTV16859DGGR from Texas Instruments. Verify pinout and electrical characteristics compatibility before substitution.

Specialty Logic FAQ

What is the function of the RESET input?

The RESET input is an asynchronous LVCMOS input that places all outputs into the LOW logic state and disables input comparators for power savings when asserted LOW.

How does the device handle clock signals?

The device uses differential clock inputs (CK and CK) to transfer input data to output data on the rising edge of the clock pair.
