ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS—Single +5V Supply

(V+ = +4.5V to +5.5V, VIH = +2.4V, VIL = +0.8V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)

(Notes 2, 9)

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.

(Voltages Referenced to GND)

V+, IN_ .....................................................................-0.3V to +6V

COM_, NC_, NO_ (Note 1) .......................... -0.3V to (V+ + 0.3V)

Continuous Current into Any Terminal .............................±30mA

Peak Current into COM_, NC_, NO_

(pulsed at 1ms, 10% duty cycle).................................±100mA

Continuous Power Dissipation (TA = +70°C)

10-Pin µMAX (derate 4.7mW/°C above +70°C) ............330mW

10-Pin Thin QFN (derate 24.4mW/°C above +70°C) ..1951mW

Operating Temperature Range .......................... -40°C to +85°C

Storage Temperature Range ........................... -65°C to +150°C

Lead Temperature (soldering, 10s) ............................... +300°C

Note 1: Signals on NO_, NC_, or COM_ exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current to maxi-

mum current rating.
