Maximum terminal current is bounded by the maximum applied voltage
across any two of the A, B, and W terminals at a given resistance, the maximum
current handling of the switches, and the maximum power dissipation of the
package; VDD = 5 V.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
Stresses above those listed under Absolute Maximum Ratings
Rating
may cause permanent damage to the device. This is a stress
−0.3 V, +8 V
rating only; functional operation of the device at these or any
0 V, V
other conditions above those indicated in the operational
DD
section of this specification is not implied. Exposure to absolute
±20 mA
maximum rating conditions for extended periods may affect
±5 mA
