Feature Description (continued)
9.3.4 Rail-to-Rail Operation
A valid analog signal for the MUX50x ranges from V_SS to V_DD. The input signal to the MUX50x can swing from
V_SS to V_DD without any significant degradation in performance. The on-resistance of the MUX50x varies with
input signal, as shown in Figure 41

9.4 Device Functional Modes
When the EN pin of the MUX50x is pulled high, one of the switches is closed based on the state of the address
lines. When the EN pin is pulled low, all the switches are in an open state irrespective of the state of the address
lines. The EN pin can be connected to V_DD (as high as 36 V).
