PROTECTION
Caution:
Transient protection is not implemented inside the CD1284 device, therefore transient voltages may cause
damage. Laboratory testing has shown that this type of protection is not necessary under normal conditions.
However, damage may occur under harsh conditions or when subjected to unusual abuse. Also note, the protection
circuit shown here may cause a powered-up host to supply power to the +5 V (V
cc
) of the peripheral if it is not
powered up. If this is a concern, then another protection circuit must be designed.
