10.6.3 SN74123
This DC triggered multivibrator has output pulse duration control by three methods. The basic
pulse time is programmed by selection of external resistance and capacitance values. Enough
Schmitt hysteresis is provided to ensure jitter-free triggering from the B input with transition
rates as slow as 0.1 mV per nanosecond.
10.6.4 SN74130N
This DC triggered multivibrator has output pulse duration control by three methods. The basic
pulse time is programmed by selection of external resistance and capacitance values.
10.7 Frequency Divider
This is an Asynchronous Binary Counter Based Frequency Divider. The amplitude of the
square wave output can be defined by the user via the dialog box. This device is ideal for use
with the virtual PLL in frequency synthesis applications.
