Power-Supply Sequencing
When using CMOS devices, care must be taken to ensure correct
power-supply sequencing. Incorrect power-supply sequencing
can result in the device being subjected to stresses beyond the
maximum ratings listed in the data sheet. Digital and analog
inputs should always be applied after power supplies and ground.
For single-supply operation, V
