Comment(by wad):

 Just a final note.   When tested over a large sample of devices in B1
 runin, it was determined that a 2 mS delay was actually required for some
 devices.   The part datasheet was re-issued with this correction.

 Instead of using a simple RC delay (which either requires a large R,
 lowering VCC at the part, or a large C, which is expensive), a switch and
 a capacitor are used in C1 and beyond.  This easily provides turn-off
 times of 4mS and cheaply fixes the problem.
