ABSOLUTE MAXIMUM RATINGS
(Voltages referenced to GND.)
VCC ......................................................................... -0.3V to +4V
All Other Pins (Note 1) ............................ -0.3V to (VCC + 0.3V)
Continuous Current IN_P/IN_N ...................................... Q30mA
Peak Current IN_P/IN_N (pulsed for 1Fs, 1% duty cycle) ..... Q100mA
Continuous Power Dissipation (TA = +70NC)

Note 1: All I/O pins are clamped by internal diodes.
Operating Temperature Range ............................ 0NC to +70NC
Storage Temperature Range .......................... -55NC to +150NC
Junction Temperature......................................................+150NC
Lead Temperature (soldering, 10s) ................................+300NC

PACKAGE THERMAL CHARACTERISTICS (Note 2)
TQFN
Junction-to-Ambient Thermal Resistance (qJA)...........29°C/W
Junction-to-Case Thermal Resistance (qJC)..................2°C/W
Note 2: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-lay-
er board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
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.
ELECTRICAL CHARACTERISTICS
(VCC = +3.0V to +3.6V, CCL = 200nF coupling capacitor on each output, RL = 50I on each output, TA = 0NC to +70NC, unless oth-
erwise noted. Typical values are at VCC = +3.3V and TA = +25NC.) (Note 3)
