Applications Information
Power-Supply Sequencing
The MAX14930–MAX14932 and MAX14130–MAX14131
do not require special power-supply sequencing. The
logic levels are set independently on either side by V_DDA
and V_DDB. Each supply can be present over the entire
specified range regardless of the level or presence of the
other supply.
Power-Supply Decoupling
To reduce ripple and the chance of introducing data errors,
bypass V_DDA and V_DDB with 0.1µF ceramic capacitors to
GNDA and GNDB, respectively. Place the bypass capacitors
as close to the power-supply input pins as possible.
