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.

(1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is
not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. All voltages are with respect to
GND. Currents are positive into and negative out of, the specified terminal.

? The D and PW packages are available taped and reeled. Add R suffix to device type (e.g. UCC2891DR) to order quantities of 2,500
devices per reel (for the D package) and 2,000 devices per reel (for the PW package). Bulk quantities are 40 units per tube (for the D
package) and 90 units per tube (for the PW package).
