What is the application suitability comparison between a switch and a logic driver?
A switch is a passive device with C-on and R-on that will attenuate the signal. A logic driver is an active device that will refresh an input signal at output by its active driving ability. Thus, compared to a logic driver, the maximum frequency of an application using a switch is limited by the trace length and the capacitive load. It is recommended to use a logic driver for applications with heavy capacitive load, long trace and high frequency.
