Note 1: Signals on COM_, NO_ exceeding V+ or V- are clamped by internal diodes. A_ and EN are clamped only to V- and can
exceed V+ up to their maximum ratings. Limit forward-diode current to maximum current rating.
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—+5V Single Supply
(V+ = +5V ±10%, V- = 0, VIH = +2.4V, VIL = +0.8V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)
