Definition of Terms

V+ to V-.

Supply Current. The supply current required from the

power supply to operate the device, excluding load currents

Frequency Range. The frequency range at the square wave

output through which circuit operation is guaranteed.

Sweep FM Range. The ratio of maximum frequency to

minimum frequency which can be obtained by applying a

sweep voltage to pin 8. For correct operation, the sweep

voltage should be within the range:

FM Linearity. The percentage deviation from the best fit

straight line on the control voltage versus output frequency

curve.

Output Amplitude. The peak-to-peak signal amplitude

appearing at the outputs.

Saturation Voltage. The output voltage at the collector of

sink current of 2mA.

Rise and Fall Times. The time required for the square wave

output to change from 10% to 90%, or 90% to 10%, of its

final value.

Triangle Waveform Linearity. The percentage deviation

from the best fit straight line on the rising and falling triangle

waveform.

Total Harmonic Distortion. The total harmonic distortion at

the sine wave output.
