• Planar PC2700 (DDR-333) RDIMMs
• High-speed data bus interfacing requiring registered buffering

Specialty Logic Procurement Notes

Verify the specific suffix 'DGG' against the manufacturer's official datasheet to confirm package dimensions and pinout compatibility. Ensure that the SSTVF series designation aligns with the required SSTL_2 interface standards for the target application. Cross-reference the part number with authorized distributors to confirm current production status and availability, as component variants may have distinct ordering information.

Specialty Logic Selection Notes

Select this component when designing systems requiring 13-to-26 bit registered buffering with SSTL_2 compatibility. The 2.5 ns propagation delay and 16 mA drive strength are suitable for DDR memory interfaces. Confirm that the 64-TSSOP package fits the PCB layout constraints and that the 0°C to +70°C operating temperature range meets the environmental requirements of the deployment scenario.

Specialty Logic Part Context

This component belongs to the SN74SSTV family of registered buffers, which are specialized for DDR memory applications. The SSTVF variant specifically denotes SSTL_2 compatibility, distinguishing it from other series like SSTV or ALVC. These devices are integral to maintaining signal integrity in high-bandwidth memory architectures used in computing and telecommunications equipment.
