While the 3-d time "re-inventing" the RS-D Trigger i came up with this 1-st
• here's the performance comparison (both perform the R/S functions at the same speed - there's some difference in D-Latch mode . . .)
in the next :: to find -- the analytical
method for converting the 2-XOR into
the 4x NAND implementation -- is
somewhat a tricky task.
+ some correlations with 3-xor
// the analogy with the 2-xor's
Provided (although simple and very easy for anyone to come up with on his'/her' own) just because I haven't spotted such in www nor in literature...
The following utilizes two types of counter cells to make a 4-bit binary and a 4-bit BCD counter.

Pre notice: the following has some numeric values listed that are to be taken with certain respect as the LT Spice (used to derive those numbers) uses an equitable , say a "P/N-MosFet-s" , to form it's quantized OUTPUT , the performance of these counter types is much dependent on actual...
