keying inputs (pins 8 and 9), as shown in the logic table
(Table 1). If a single timing resistor is activated, the
frequency is 1/RC. Otherwise, the frequency is either

Figure 13Bshows a fixed frequency application using a
single timing resistor that is selected by grounding the
binary keying inputs. The oscillator frequency is 1/R

C.
The squarewave output is obtained at pin 13 and has a
peak-to-peak voltage swing equal to the supply voltages.
This output is an “open-collector” type and requires an
external pull-up load resistor (nominally 5k
) to the
positive supply. The triangle waveform obtained at pin 14
is centered about ground and has a peak amplitude of
V
+
/2.
Note
For Single-Supply Operation, Logic Levels are referenced to
voltage at Pin 10.
