Figure 8 . F/V Digital Outputs
Input Buffer
f
OUT
and f
OUT
/2 are not used in the F/V mode. However,
these outputs may be useful for some applications, such as
a buffer to feed additional circuitry. Then, f
OUT
will follow the
input frequency waveform, except that f
OUT
will go high
3
μ
sec after f
IN
goes high; f
OUT
/2 will be squarewave with a
frequency of one-half f
OUT
.
If these outputs are not used, pins 8, 9 and 10 should be
connected to ground.
