Operating ratings indicate conditions the device is intended t o be 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. Note 2: The positive input voltage limit is 30V above the negative supply voltage. The negative input voltage limit is equal to the negative supply voltage or 3 0V below the positive supply voltage, whichever is less. Note 3: The offset voltage and offset current limits are the maximum values required to drive the output within a volt of either supply wit ha1m A load. Therefore, these parameters define an error band and take into account the worst-case effects of voltage gain and input impedance. Note 4: This specification is for a 100 mV input step with a 25 mV overdrive. LM6511 www.national.com 2

Note 5: This specification gives the range of current which must be drawn from the strobe pin to ensure the output is properly disabled. Do not short the strobe pin to ground; it should be current driven at 3 mA to 5 mA.

By biasing the input to 1⁄2 of the input logic supply (V A), this assures that this input remains within the input voltage range. The pull-up resistor should go to the output logic supply (V B).
