MC10E431, MC100E431
5 V ECL 3‐Bit Differential
Flip‐Flop
Description The MC10E/100E431 is a 3-bit flip-flop with differential clock,
data input and data output. The asynchronous Set and Reset controls are edge-triggered rather
than level controlled. This allows the user to rapidly set or reset the flip-flop and then continue clocking at the next clock edge, without the necessity of de-asserting the set/reset signal (as would be the case with a level controlled set/reset).
The E431 is also designed with larger internal swings, an approach intended to minimize the time spent crossing the threshold region and thus reduce the metastability susceptibility window.
