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
DD
will usually be
sufficient to pulse the TC9400 and provide a power-on reset
(see Figure 11A). Where predictable power-on operation is
critical, a more complicated circuit, such as Figure 11B, may
be required.

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
IN
. In most
frequency-measurement applications this is not a problem,
because proper operation begins as soon as the frequency
input is applied.
