Note 1) <Notes on load connection>
Note 2) In Fig.8.5, the first stage is assigned to double boosting and the next-stage to triple boosting; however,
Note 3) When double boosting is provided in the first stage, the first-stage CAP1- output can be used as a
Note 4) In serial connection, the temperature gradient is provided to the V
As shown in Fig.8.5, when connecting load between V
serial connection, take care of the following points:
When the IC is activated or no normal output is generated at the V
signal, current is supplied from V
If the voltage exceeds the absolute maximum rating above V
normal operation. For serial connection, as shown in Fig.8.5, connect diode D1 between V

triple boosting is available for both the first and next stages unless the input voltage V
next stage exceeds the standard value (6V). For serial connection, each IC must be designed in
conformity with the standard (V
next-stage clock; however, when triple boosting is provided, it cannot be used as a next-stage clock.
Therefore, to obtain a next-stage clock, mount R
As shown in Table 5.1, the next-stage external clock operation by the pre-stage CAP1- output is
available only for temperature gradient C
