Micrel SY100E431

The SY10/100E431 are 3-bit flip-flops with differential clock, data input and data output. The asynchronous Set and Reset controls are edgetriggered 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).

DESCRIPTION

The E431 is also designed with larger internal swings, an approach intended to minimize the time spent crossing the threshold region and thus reduces the metastability susceptibility window.
