Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits are
exceeded, device functional operation is not implied, damage may occur and
reliability may be affected.

Applications Information
Suppressing Noise at the Source
Filter all I/O signals leaving the noisy environment
Locate I/O driver circuits close to the connector
Use the longest rise/fall times possible for all digital signals
Reducing Noise at the Receiver
Filter all I/O signals entering the unit
Locate the I/O filters as close as possible to the connector
Minimizing Noise Coupling
Use multilayer PCBs to minimize power and ground inductance
Keep clock circuits away from the I/O connector
Ground planes should be used whenever possible
Minimize the loop area for all high speed signals
Provide for adequate power decoupling
ESD Protection
Locate the suppression devices as close to the I/O connector as possible
Minimize the PCB trace length to the suppression device
Minimize the PCB trace length for the ground return for the suppression device
