In F/V mode, the TC9400 output voltage will occasion-
ally be at its maximum value when power is first
applied. This condition remains until the first pulse is
applied to F
applications, this is not a problem because proper
operation begins as soon as the frequency input is
applied.

In some cases, however, the TC9400 output must be
zero at power-on without a frequency input. In such
cases, a capacitor connected from Pin 11 to V
usually be sufficient to pulse the TC9400 and provide a
Power-on Reset (see
predictable power-on operation is critical, a more
complicated circuit, such as
required.
