Each of the 13 elements handles 26 bits, giving a total of 338 bits of buffered signal path. The part operates from a 2.3V to 2.7V supply, matching the SSTL-2 (Stub Series Terminated Logic for 2.5V) standard used in DDR1 memory interfaces. Output drive is symmetric at 16mA high and low, sufficient for driving multiple DIMM loads on a heavily loaded memory bus. ## Fine-pitch TSSOP — rework and layout notes Housed in a 64-TFSOP (0.240\", 6.10mm width) package, also specified as a 64-TSSOP supplier device package, this is a fine-pitch surface-mount part with 0.5mm lead pitch. The narrow body and dense pin count demand careful solder-paste stencil design and a reflow profile that avoids tombstoning. Under a hot-air station, the part lifts cleanly if you preheat the board to 100°C and work the leads from the long sides — the thermal mass is low, so it reflows fast. The package is MSL 3 per standard Cypress TSSOP handling — bake before reflow if the moisture-barrier bag has been open past the floor-life window. It is not specified for industrial or automotive temperature extremes. If your application sees below-freezing startup or sustained heat above 85°C, look for an industrial-temperature variant in the same family. ## RoHS non-compliant — legacy solder finish The CY2SSTV16859ZC is listed as RoHS non-compliant, meaning the device uses a lead-bearing solder finish (likely SnPb). If your assembly line is RoHS-only, you will need to qualify a lead-free alternative or apply for an exemption.","metaTitle":"CY2SSTV16859ZC Buffer, Non-Inverting, 64-TSSOP, 2.3V–2.7V","metaDescription":"CY2SSTV16859ZC is a 13-element, 26-bit non-inverting buffer in 64-TSSOP.
