NOTES FOR CMOS DEVICES
1
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.

STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note:
Power-on does not necessarily define initial status of MOS device. Production 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 immediately after power-on for devices
having reset function.
HANDLING OF THE APPLIED WAVEFORM OF INPUT PINS AND THE UNUSED INPUT PINS
FOR CMOS
Input levels of CMOS devices must be fixed. CMOS devices behave differently than Bipolar or
NMOS devices. If the input of a CMOS device stays in an area that is between V
IL
(MAX.) and
V
IH
(MIN.) due to the effects of noise or some other irregularity, malfunction may result.
Therefore, not only the input waveform is fixed, but also the waveform changes, it is important
to use the CMOS device under AC test conditions. For unused input pins in particular, CMOS
devices should not be operated in a state where nothing is connected, so input levels of CMOS
devices must be fixed to high or low by using 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.
