DC Analog Mux Bus Specifications
Table 15 lists the guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75 V to 5.25 V and
–40 °C ≤ T_A ≤ 85 °C, 3.0 V to 3.6 V and –40 °C ≤ T_A ≤ 85 °C, or 2.4 V to 3.0 V and –40 °C ≤ T_A ≤ 85 °C, respectively. Typical param-
eters apply to 5 V, 3.3 V, or 2.7 V at 25 °C. These are for design guidance only.
