Absolute Maximum Ratings
Stresses greater than those listed in this table may cause per-
manent damage to the device. These represent a stress rating
only. Operation of the device at these or any other conditions
above those specified in the operating sections of this specifi-
cation is not implied. Maximum conditions for extended peri-
ods may affect reliability

Notes:
1. If crystal is used as input Crystal Load Capacitance (C_L) = 12 pF.
2. If a clock is used as input, the duty cycle of the 14.318-MHz output will be the same as the input clock.
