ABSOLUTE MAXIMUM RATINGS
(Voltages referenced to GND.)
VCC ...................................................................... -0.3V to +4.0V
All Other Pins (Note 1) ............................ -0.3V to (VCC + 0.3V)
Continuous Current RX_+, RX_-, TX_+, TX_-.................. Q30mA
Continuous Power Dissipation (TA = +70NC)
TQFN (derate 27.8mW/NC above +70NC) ............. 2222.2mW
Operating Temperature Range ............................ 0NC to +70NC
Junction Temperature Range ......................... -40NC to +150NC
Storage Temperature Range .......................... -65NC to +150NC
Lead Temperature (soldering, 10s) ................................+300NC
Soldering Temperature (reflow) ......................................+260NC
Note 1: All I/O pins are clamped by internal diodes.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion 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.
PACKAGE THERMAL CHARACTERISTICS (Note 2)
TQFN
Junction-to-Ambient Thermal Resistance (qJA).......... 36NC/W
Junction-to-Case Thermal Resistance (qJC)..................3NC/W
Note 2: 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.maxim-ic.com/thermal-tutorial.
ELECTRICAL CHARACTERISTICS
(VCC = +3.0V to +3.6V, CC = 100nF coupling capacitor on each output, RL = 50I and CL = 1pF on each output, TA = 0NC to +70NC,
unless otherwise noted. Typical values are at VCC = +3.3V and TA = +25NC.)
