Quad Serial UART with 128-Word FIFOs
MAX14830
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.

DC ELECTRICAL CHARACTERISTICS
(VA = +2.35V to +3.6V, VL = +1.71V to +3.6V, VEXT = +1.71V to +3.6V, TA = -40NC to +85NC, unless otherwise noted. Typical values
are at VA = +2.5V, VL = +1.8V, VEXT = +2.8V, TA = +25NC.) (Notes 2, 3)
ABSOLUTE MAXIMUM RATINGS
Note 1: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer
board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
