NTE994M
Integrated Circuit
Voltage Controlled Oscillator
Description:
The NTE994M is a general purpose voltage controlled oscillator in an 8鈥揕ead DIP type package
which may be used to generate square and triangular waves, the frequency of which is a very linear
function of a control voltage. The frequency is also a function of an external resistor and capacitor.
The NTE994M is specified for operation over the 0擄C to +70擄C temperature range.
