The absolute maximum ratings in the following table are stress ratings only. Operation at or beyond these
maximum ratings may cause permanent damage to the device.

Operating Conditions
The STB0210x Digital Set-Top Box Integrated Controller can interface to either 3.3 V or 5 V technologies. 5 V
interfaces are supported only for drivers/receivers supporting 5 V tolerance (see
range for supply voltages is specified for five-percent margins relative to a nominal 2.5 V and 3.3 V power
supply.
Note: Device operation beyond the conditions specified in the table below is not recommended. Extended
operation beyond the recommended conditions may affect device reliability.
Power Considerations
Power dissipation is determined by operating frequency, temperature, and supply voltage, as well as external
source/sink current requirements.
Recommended Connections
Power and ground pins should all be connected to separate power and ground planes in the circuit board to
which the STB0210x is mounted. Unused input pins must be tied inactive, either high or low.
