influence to the normal operation and reliability of the device.
These devices are without built-in overheat protection function.
Be careful not to apply electro static discharge to the device since this device employs a CMOS IC and may be damaged by electro
static discharge. Followings are some methods against excessive voltage caused by electro static discharge.
(1) Please perform shortest wiring for connection between C
(2) The input terminal for ON/OFF output control is compatible with LS-TTL, and direct driving by TTL or C-MOS standard logic
(3) If voltage is applied under the conditions that the device pin is connected divergently or reversely, the deterioration of
(4) If voltage exceeding the voltage of DC input terminal 1 is applied to
(1) Human body must be grounded to discharge the static electricity from the body or cloth.
(2) Anything that is in contact with the device such as workbench, inserter, or measuring instrument must be grounded.
(3) Use a solder dip basin with a minimum leak current (isolation resistance 10M or more) from the commercial power supply.
