MC68HC812A4 Maximum Ratings

Rating	Symbol	Value	Unit
Supply voltage	V_DD V_DDA V_DDX	0.3 to +6.5	V
Input voltage	V_In	0.3 to +6.5	V
Maximum current per pin excluding V_DD and V_SS	I_In	± 25	mA
Storage temperature	T_STG	55 to +150	°C
V_DD differential voltage	V_DDV_DDX	6.5	V

NOTE: This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields; however, it is advised that normal precautions be taken to avoid application of any voltage higher than maximum-rated voltages to this high-impedance circuit. For proper operation, it is recommended that V_In and V_Out be constrained to the range V_SS (V_In or V_Out) V_DD. Reliability of operation is enhanced if unused inputs are connected to an appropriate logic voltage level (for example, either V_SS or V_DD).
