The SY10/100E431 are 3-bit flip-flops 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 reduces the metastability
susceptibility window.

NOTES:
1. V
CMR
is referenced to the most positive side of the differential input signal. Normal operation is obtained when the input signals are within the V
CMR
range
and the input swing is greater than V

(min.) and <1V.

NOTES:
1. These set-up times define the minimum time the CLK or SET/RESET input
must wait after the assertion of the RESET/SET input to assure the proper
operation of the flip-flop.
2. Within-device skew is defined as identical transitions on similar paths
through a device.
3. Minimum input swing for which AC parameters are guaranteed.
