SY100E431 3-BIT DIFFERENTIAL
FLIP-FLOP Micrel, Inc. SY10E431
SY100E431 DESCRIPTION FEATURES
в– Differential D, clock and Q 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).
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. ■Extended 100E VEE range of –4.2V to –5.5V
в– VBB output for single-ended use
в– 1100MHz min. toggle frequency
в– Edge-triggered asynchronous set and reset
в– Fully compatible with Motorola MC10E/100E431
в– Available in 28-pin PLCC package PIN NAMES BLOCK DIAGRAM
