This gives a total of ten clock outputs from two independent buffer paths on one 20-SSOP package. The non-differential I/O path means it is intended for single-ended clock trees, not differential pairs like LVPECL or LVDS. ## Industrial temperature and package fit The supply voltage tolerance (3V to 3.6V) covers the full 3.3V ±10% range, including the 3.0V low end that some 3.3V LDOs drift to under load. No external regulator adjustment is needed if the rail stays within this window. It is RoHS3 compliant (lead-free per EU 2015/863), so it clears the regulatory gate for new builds without a waiver. The tube packaging is the standard handling format for prototype and low-volume assembly. For reel quantities, check the suffix variant — the 'PYGI' ordering code denotes the SSOP tube option.","metaTitle":"Renesas 49FCT3805PYGI Fanout Buffer, 1:5, 20-SSOP","metaDescription":"Active Renesas 49FCT3805PYGI fanout buffer, 2 circuits, 1:5 ratio, 3V-3.6V supply, -40°C to 85°C, 20-SSOP.
