ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(VCC = +2.3 to +5.5V, TA = TMIN to TMAX, CNEG = 3.3nF, unless otherwise noted. Typical values are at VCC = +3.0V, TA = +25°C,

unless otherwise noted.) (Note 3)

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.

Note 1: Signals on NC_, NO_, and COM_ exceeding -VCC or +VCC are clamped by internal diodes. For EN ≥ VIH signals on NC_,

NO_, and COM_ exceeding 0 or +VCC are clamped by internal diodes (MAX14505A/MAX14506). Limit forward-diode current

to maximum current rating.

Note 2: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a 4-layer

board. For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial.

(All voltages referenced to GND, unless otherwise noted.)
