ELECTRICAL SPECIFICATIONS
This section contains the electrical specications and associated timing information for the
MC68HC05F4.
10.1
Maximum ratings
Note:
This device contains circuitry designed to protect against damage due to high
electrostatic voltages or electric elds. However, it is recommended that normal
precautions be taken to avoid the application of any voltages higher than those given
in the Maximum Ratings table to this high impedance circuit. For maximum reliability all
unused inputs should be tied to either VSS or VDD.
(1) All voltages are with respect to VSS.
(2) Maximum current drain per pin is for one pin at a time, limited by an external resistor.
