L9348
(1).See chapter 2.0 Timing Diagrams; resistive load condition; VS ≥ 9V
(2).This parameter will not be tested but assured by design
(3).Wafer-measurement
(4).Measured on P-SO36 devices
(5).Short circuit between two digital outputs (one in high the other in low state) will lead to the defined result "LOW"
