GENERAL DESCRIPTION
The ADG5421/ADG5423 are monolithic industrial, complementary metal oxide semiconductor (CMOS) analog switches containing two independent latch-up immune singlepole/single-throw (SPST) switches. Each switch conducts equally well in both directions when on, and has an input signal range that extends to the power supplies. In the off condition, signal levels up to the supplies are blocked. Both ADG5421 switches are turned on with a Logic 1 input, whereas the ADG5423 has one switch turned on and one switch turned off for a Logic 1 input. The ADG5423 exhibits break-before-make action for use in multiplexer applications. The ultralow on resistance and on-resistance flatness of these switches make them id……
