What the CDC318ADL is and where it fits
This is a commercial-temperature-grade device (0°C to 70°C), so it is suited for indoor equipment, office electronics, and appliance PCBs rather than industrial or automotive environments. 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.
