Characteristics  
All voltages are referenced to VSS = 0 V (ground).  
All characteristics are valid in the power supply voltage range and in the operating temperature range specified.  
Dynamic measurements are based on a rise and fall time of 5 ns, measured between 10 % and 90 % of VI, as well as  
input levels of VIL = 0 V and VIH = 3 V. The timing reference level of all input and output signals is 1.5 V,  
with the exception of the tdis-times and ten-times, in which cases transition is measured ± 200 mV from steady-state voltage.

a: Stresses greater than those listed under „Absolute Maximum Ratings“ may cause permanent damage to the device. This is a stress  
rating only, and functional operation of the device at condition above those indicated in the operational sections of this specification is  
not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
