The non-differential I/O (No/No) means it works with single-ended LVTTL rails, not differential pairs like LVPECL or LVDS. ## 1:18 fanout and 100 MHz — what they mean for the BOM The 1:18 ratio is the key selection parameter: one input drives eighteen loads. That saves board space and part count compared to cascading lower-fanout buffers. The 100 MHz maximum frequency covers most microcontroller and FPGA clock trees running below that speed, but it will not handle gigabit-rate serial links or high-speed memory interfaces. ## Sourcing and lifecycle The CDC318ADL is listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect.","metaTitle":"CDC318ADL Fanout Buffer, 1:18, 100 MHz, 48-SSOP","metaDescription":"CDC318ADL fanout buffer (distribution), 1:18 ratio, 100 MHz max, LVTTL I/O, 3.135V–3.465V supply, 48-SSOP.
