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.
2 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 devices 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 VDD 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. 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
notinitializeduntiltheresetsignalisreceived. Resetoperationmustbeexecutedimmediately
after power-on for devices having reset function.

Caution Purchase of NEC I2C components conveys a license under the Philips I2C Patent Rights to use
these components in an I2C system, provided that the system conforms to the I2C Standard
Specification as defined by Philips.

While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor
devices, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to
persons or property arising from a defect in an NEC semiconductor device, customers must incorporate
sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features.
NEC devices are classified into the following three quality grades:
“Standard”, “Special”, and “Specific”. The Specific quality grade applies only to devices developed based
on a customer designated “quality assurance program” for a specific application. The recommended
applicationsofa device depend on its quality grade, asindicatedbelow. Customersmustcheckthequality
grade of each device before using it in a particular application.
Standard: Computers,officeequipment,communicationsequipment,testandmeasurementequipment,
audio and visual equipment, home electronic appliances, machine tools, personal electronic
equipment and industrial robots
Special: Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-
disastersystems,anti-crimesystems,safetyequipmentandmedicalequipment(notspecifically
designed for life support)
Specific: Aircrafts,aerospace equipment, submersiblerepeaters,nuclearreactor control systems,life
support systems or medical equipment for life support, etc.
The quality grade of NEC devices is “Standard” unless otherwise specified in NEC’s Data Sheets or Data
Books.
If customers intend to use NEC devices for applications other than those specified for Standard quality
grade, they should contact an NEC sales representative in advance.
Anti-radioactive design is not implemented in this product.
