Precautions for Safe Use and Notices
If semiconductor devices are handled inappropriate manner, failures may result. For this
reason, be sure to read this “Application Guide” before use.
This mark indicates an item about which caution is required.
This mark indicates a potentially hazardous situation which,
if not avoided, may result in minor or moderate injury and
damage to property
(1) Regardless of changes in external conditions during use “absolute maximum
ratings” should never be exceed in designing electronic circuits that employ
semiconductors. In the case of pulse use, furthermore,″safe operating
area(SOA)”precautions should be observed.
(2) Semiconductor devices may experience failures due to accident or unexpected
surge voltages. Accordingly, adopt safe design features, such as redundancy or
prevention of erroneous action, to avoid extensive damage in the event of a failure.
(3) In cases where extremely high reliability is required (such as use in nuclear power
control, aerospace and aviation, traffic equipment, life-support-related medical
equipment, fuel control equipment and various kinds of safety equipment), safety
should be ensured by using semiconductor devices that feature assured safety or
by means of user’s fail-safe precautions or other arrangement. Or consult Hitachi’s
sales department staff.
(If a semiconductor device fails, there may be cases in which the semiconductor
device, wiring or wiring pattern will emit smoke or cause a fire or in which the
semiconductor device will burst)
