ABSOLUTE MAXIMUM RATINGS
(All voltages referenced to GND, unless otherwise noted.)
V_CC ........................................................................-0.3V to +6.0V
NC_, NO_, COM_ (Note 1)..................-V_CC - 0.3V to V_CC + 0.3V
NC_, NO_, COM_ (MAX14505A/MAX14506, EN = V_CC)
(Note 1) .......................................................-0.3V to V_CC + 0.3V
CB, EN......................................................................-0.3V to +6V
Continuous Current (NC_, NO_, COM_).........................±550mA
Continuous Current on Shunt Switches ..............................±5mA
Peak Current (NC_, NO_, COM_)
(pulsed at 1ms, 10% duty cycle)..................................±850mA
Continuous Power Dissipation (T_A = +70°C) for multilayer board:
12-Pin WLP (derate 8.5mW/°C above +70°C) ..............678mW
Operating Temperature Range ...........................-40°C to +85°C
Junction Temperature ......................................................+150°C
Storage Temperature Range .............................-65°C to +150°C
Package Junction-to-Ambient Thermal
Resistance (θ_JA) (Note 2)............................................118°C/W
Lead Temperature (soldering) .........................................+300°C
Note 1: Signals on NC_, NO_, and COM_ exceeding -V_CC or +V_CC are clamped by internal diodes. For EN ≥ V_IH signals on NC_,
NO_, and COM_ exceeding 0 or +V_CC 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.
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
(V_CC = +2.3 to +5.5V, T_A = T_MIN to T_MAX, C_NEG = 3.3nF, unless otherwise noted. Typical values are at V_CC = +3.0V, T_A = +25°C,
unless otherwise noted.) (Note 3)
