NOTE:
1. All parameters are specifications of the HIP7010 component not of a system. Parameters specified as “Required” (i.e., t
STATH
) refer to
the requirements of the HIP7010. If a “Required” pulse width is specified as 75ns maximum, that implies that 75ns is the maximum width
that any HIP7010 device will require. Therefore, a system that provides a
minimum
pulse width of 75ns will satisfy this
maximum
requirement.
