TOP MARKING
The actual physical placement of the package marking will vary from part to part. The package marking "X"
designates the single digit date code. "V" is a NSC internal code for die traceability. Both will vary considerably. "DL"
identifies the device (part number, option, etc.).

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
