It accepts a single CMOS input and delivers four CMOS outputs, making it suitable for non-differential clock trees in systems where signal integrity at the fan-out node is the main concern. ## Supply range and temperature grade Compared to the 5PB1104CMGK/W, which operates from 1.71V and over -40°C to 105°C, the 551MLF requires a higher minimum supply and cannot serve cold-start or high-temp environments. ## Package and footprint compatibility Housed in an 8-SOIC (0.154\", 3.90mm width) surface-mount package, the 551MLF uses a standard footprint that routes easily on two-layer boards — no fine-pitch fan-out required.","metaTitle":"551MLF Renesas Clock Buffer 1:4 160MHz 8-SOIC","metaDescription":"551MLF fanout buffer, 1:4 CMOS, 160 MHz max, 3V-5.5V supply, 8-SOIC.
