The MC68HC908GT16 and the MC68HC908GT8 are members of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCUs). All MCUs in the family use the enhanced M68HC08 central processor unit (CPU08) and are available with a variety of modules, memory sizes and types, and package types. All references to the MC68HC908GT16 in this data book apply equally to the MC68HC908GT8, unless otherwise stated.
MC68HC908GT16 Maximum Ratings
Maximum ratings are the extreme limits to which the microcontroller unit (MCU) can be exposed without permanently damaging it. NOTE:This device is not guaranteed to operate properly at the maximum ratings. Refer to 20.5 5.0-V DC Electrical Characteristics for guaranteed operating conditions.

1. Voltages referenced to VSS 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 VIn and VOut be constrained to the range VSS (VIn or VOut) VDD. Reliability of operation is enhanced if unused inputs are connected to an appropriate logic voltage level (for example, either VSS or VDD).
