PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note: Strong electric field, when exposed to a MOS device, can cause destruction
of the gate oxide and ultimately degrade the device operation. Steps must
be taken to stop generation of static electricity as much as possible, and
quickly dissipate it once, when it has occurred. Environmental control must
be adequate. When it is dry, humidifier should be used. It is recommended
to avoid using insulators that easily build static electricity. Semiconductor
devices must be stored and transported in an anti-static container, static
shielding bag or conductive material. All test and measurement tools
including work bench and floor should be grounded. The operator should
be grounded using wrist strap. Semiconductor devices must not be touched
with bare hands. Similar precautions need to be taken for PW boards with
semiconductor devices on it.

HANDLING OF UNUSED INPUT PINS FOR CMOS
Note: No connection for CMOS device inputs can be cause of malfunction. If no
connection is provided to the input pins, it is possible that an internal input
level may be generated due to noise, etc., hence causing malfunction. CMOS
device behave differently than Bipolar or NMOS devices. Input levels of
CMOS devices must be fixed high or low by using a pull-up or pull-down
circuitry. Each unused pin should be connected to V
DD
or GND with a
resistor, if it is considered to have a possibility of being an output pin. All
handling related to the unused pins must be judged device by device and
related specifications governing the devices.
3
STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note: Power-on does not necessarily define initial status of MOS device. Produc-
tion process of MOS does not define the initial operation status of the
device. Immediately after the power source is turned ON, the devices with
reset function have not yet been initialized. Hence, power-on does not
guarantee out-pin levels, I/O settings or contents of registers. Device is not
initialized until the reset signal is received. Reset operation must be
executed imme-diately after power-on for devices having reset function.
