Is there any PC-Board noise generated when interfacing CMOS outputs to TTL inputs? How about TTL to HCT? Is CMOS to HCT less noisy than CMOS to TTL? I have a spec for a CMOS ADC chip that states, for less noise, only connect outputs (of the ADC) to CMOS inputs, yet I need some way of connecting some control signals of the CMOS part to TTL inputs. Noise is a critical factor, as I am hoping to get 16-bit sampling.
