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 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. 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.
