SPECIFICATIONS AND CHARACTERISTICS

ABSOLUTE MAXIMUM RATINGS

(AVSS, DVSS = 0 V, all voltages with respect to 0 V.)

WARNING:

Operation at or beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.

RECOMMENDED OPERATING CONDITIONS

(AVSS, DVSS = 0 V, all voltages with respect

to 0 V.)

QUARTZ CRYSTAL REQUIREMENTS

(If a 25 MHz quartz crystal is used, it must meet the fol-

lowing specifications.)
