The recommended parameter range for C
are many factors (board layout, etc) that can affect characteristics. Please verify and confirm using practical applications.
Due to the capabilities of the CT pin discharge transistor, the CT pin may not completely discharge when a short input
pulse is applied, and in this case the delay time may not be controlled. Please verify the actual operation.
Please note that the power on reset output varies with the Vcc rise up time. Please verify the actual operation.
Connecting low-impedance capacitors to run inspections with the board may produce stress on the IC.
Therefore, be certain to use proper discharge procedure before each process of the test operation.
To prevent electrostatic accumulation and discharge in the assembly process, thoroughly ground yourself and any
equipment that could sustain ESD damage, and continue observing ESD-prevention procedures in all handing, transfer
and storage operations. Before attempting to connect components to the test setup, make certain that the power supply is
OFF. Likewise, be sure the power supply is OFF before removing any component connected to the test setup.
unsettled, the couple capacitance, GND pattern of width and leading line must be considered.
