(VCC = 2.7V to 5.5V, TA = -40°C to +125°C, unless otherwise noted. Typical values are at VCC = 5V and TA = +25°C.) (Note 1)

Note 1: All parameters are tested at TA = +25°C. Specifications over temperature are guaranteed by design.

Note 2: The frequency is determined by part number selection. See Table 1.

Note 3: Guaranteed by design. Not production tested.

Note 4: Guaranteed by design. Part will function outside tested range.

Absolute Maximum Ratings

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these

or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect

device reliability.
