NOTES: 1. These frequencies exceed the upper limit of 100kHz of the I2C-bus specification and cannot be used in an I2C-bus application. 2. At fOSC = 24 MHz the maximum I2C bus rate of 100kHz cannot be realized due to the fixed divider rates. ABSOLUTE MAXIMUM RATINGS1, 2, 3 PARAMETER RATING UNIT Storage temperature range –65 to +150 °C Voltage on any other pin to VSS –0.5 to +6.5 V Input, output DC current on any single I/O pin 5.0 mA Power dissipation (based on package heat transfer limitations, not device power consumption) 1.0 W NOTES: 1. Stresses above 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 these or any conditions other than those described in the AC and DC Electrical Characteristics section of this specification is not implied. 2. This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive static charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maxima. 3. Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to VSS unless otherwise noted.
