SEMICONDUCTOR TECHNICAL DATA
Voltage Controlled
Multivibrator
The MC1658 is a voltage–controlled multivibrator which provides
appropriate level shifting to produce an output compatible with MECL III
and MECL 10,000 logic levels. Frequency control is accomplished
through the use of voltage–variable current sources which control the
slew rate of a single external capacitor.
The bias filter may be used to help eliminate ripple on the output
voltage levels at high frequencies and the input filter may be used to
decouple noise from the analog input signal.
