Digital Timing Characteristics
The following specifications apply for V
A+ = VD+ = 3.3V, tr = tf = 3 ns, and CL = 100 pF on data I/O, INT and DMARQ lines
unless otherwise specified. Boldface limits apply for T
A = TJ = TMIN to TMAX; all other limits TA = TJ = 25˚C. (Notes 6, 7, 8)

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is func-
tional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed speci-
fications 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 GND, unless otherwise specified.
Note 3: When the input voltage (VIN) at any pin exceeds the power supply rails (VIN < GND or VIN > (VA+orVD+)), the current at that pin should be limited to 5 mA.
The 20 mA maximum package input current rating allows the voltage at any four pins, with an input current of 5 mA, to simultaneously exceed the power supply volt-
ages.
Note 4: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature), θJA (package junction
to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is PDmax = (TJmax −TA)/θJA or the num-
ber given in the Absolute Maximum Ratings, whichever is lower. For this device, TJmax = 150˚C, and the typical thermal resistance (θJA) of the LM12L454 and
LM12L458 in the V package, when board mounted, is 47˚C/W.
Note 5: Human body model, 100 pF discharged through a 1.5 k
Ω resistor.
Note 6: Two on-chip diodes are tied to each analog input through a series resistor, as shown below. Input voltage magnitude up to 5V above VA+ or 5V below GND
will not damage the LM12L458. However, errors in the A/D conversion can occur if these diodes are forward biased by more than 100 mV. As an example, if VA+is
3.0 VDC, full-scale input voltage must be ≤3.1 VDC to ensure accurate conversions.
