FILTER CIRCUITS FOR PROTECTING AGAINST TRANSIENT ELECTRICAL PULSES
An integrated circuit package having primary circuitry, an ESD protection device (14), a filter circuit (102), and a conductive lead (16) arranged to couple a point (V+) external to the integrated circuit package to a point (VF+) internal to the integrated circuit package. The ESD device, coupled in series between the conductive lead and a ground reference (20), can limit the voltage magnitude of a transient electrical pulse occurring upon the conductive lead. The filter circuit is operable such that the voltage magnitude of an electrical signal generated at the filter circuit output (VF+) is less than the voltage magnitude of the certain transient electrical pulse itself.
