Freescale Semiconductor

MMA7456L

ELECTRO STATIC DISCHARGE (ESD)

WARNING: This device is sensitive to electrostatic discharge.

Although the Freescale accelerometer contains internal 2000V ESD protection circuitry, extra precaution must be taken by the

user to protect the chip from ESD. A charge of over 2000 volts can accumulate on the human body or associated test equipment.

A charge of this magnitude can alter the performance or cause failure of the chip. When handling the accelerometer, proper ESD

precautions should be followed to avoid exposing the device to discharges which may be detrimental to its performance.
