pins could suffer long term damage when driven to +5V. If this condition is
seen in the application, it can be corrected with additional circuitry to use the

ESD (electrostatic discharge) sensitive device.
Charged devices and circuit boards can discharge
without detection. Although this product features
patented or proprietary protection circuitry, damage
may occur on devices subjected to high energy ESD.
Therefore, proper ESD precautions should be taken to
avoid performance degradation or loss of functionality.
