Boring  mode - ON

With reference to the subject matter and my previous posting,  I can
confirm in the true Orwellian manner that all 74HC4046 devices are  equal
except that some are more equal than others. Mine, a NS labeled  device,
will not tolerate DC coupling along with long pulse inputs  whereas
others (I think those from NXP [Philips]) will. Another, but  messy
solution, is to AC couple them and clamp the negative-going peaks  to
ground.

Boring mode - OFF



Not boring at all, such information is always useful.
 
Did you establish whether or not the EPE version uses the original  Silicon 
Chip circuit or the corrected one?
