1Typical data are for initial design estimations only, and assume optimum manufacturing and application conditions, such as TA = 25°C. Performance
may vary for individual units, within the specified maximum and minimum limits.
2Operate points, BOPX, and release points, BRPX, vary with supply voltage.
3Maximum VDD, minimum 0 V.
