*$
* This model is for the old bipolar 555 supplied by National
* Semi Lm555, it is essentially the data schematic entered
* with some manipulation of the bipolar parameters to correct
* drive capability and timing. The max frequency of 100k as
* hinted at by Nat Semi is maintained but does conflict with
* the trigger propagation delay. It would seem that the real part
* is capable of higher freqs. The high current transients with
* change of output are seen with this model.
