have a low ESR (equivalent series resistance) rating to ensure the quick response time. They should also
be connected to the power and ground planes through two vias to minimize inductance. Suggested bulk
capacitors are 100–330 µF (AVX TPS tantalum or Sanyo OSCON).

To ensure reliable operation, connect unused inputs to an appropriate signal level. Unused active low
inputs should be tied to OV
connected to GND. All NC (no-connect) signals must remain unconnected.
Power and ground connections must be made to all external V
the MPC8349EA.

The MPC8349EA drivers are characterized over process, voltage, and temperature. For all buses, the
driver is a push-pull single-ended driver type (open drain for I
