Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Operating Ratings indicate conditions for which the device is functional, but do not
guarantee specific performance limits. For guaranteed specifications and test
conditions, see the Electrical Characteristics. The guaranteed specifications apply
only for the test conditions listed. Some performance characteristics may degrade
when the device is not operated under the listed test conditions.
Note 2:
All voltages are measured with respect to Agnd and Dgnd, unless otherwise specified.
Note 3:
When the input voltage (Vin) at any pin exceeds the power supply rails (Vin < V- or
Vin >(AVcc or DVcc), the current at that pin should be limited to 5mA. The 20mA
maximum package input current rating allows the voltage at any four pins, with an
input current limit of 5mA, to simultaneously exceed the power supply voltages.
Note 4:
The power dissipation of this device under normal operation should never exceed 191mW
(Quiescent Power Dissipation + 1 TTL Load on each digital output). Caution should be
taken not to exceed absolute maximum power rating when the device is operating in
severe fault condition (ex. when any inputs or outputs exceed the power supply). The
maximum power dissipation must be derated at elevated temperatures and is dictated by
Tjmax (maximum junction temperature), ThetaJA (package junction to ambient thermal
resistance), and TA (ambient temperature). The maximum allowable power dissipation at
any temperature is Pdmax = (Tjmax - TA)/ThetaJA or the number given in the Absolute
Maximum Ratings, whichever is lower. For this device, Tjmax = 150 C.
Note 5:
Human body model, 100pF discharged through a 1.5K Ohm resistor.
Note 6:
A diode exists between AVcc and DVcc. To guarantee accuracy, it is required that the
AVcc and DVcc be connected together to a power supply with separate bypass filters at
each Vcc pin.
