Operating ratings indicate conditions the device is intended to 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 30V 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 witha1m 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. 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. www.national.com 2

Universal Logic Level Shifter DS011888-4 Notes:Because of the very wide operating and output voltage range, the LM6511 may be used to shift logic levels from 3V to TTL or CMOS to the other way around. By biasing the input to1⁄2 of the input logic supply (VA), this assures that this input remains within the input voltage range. The pull-up resistor should go to the output logic supply (VB). www.national.com5
