The SY100S331 offers three D-type, edge-triggered
master/slave flip-flops with true and complement outputs,
designed for use in high-performance ECL systems. Each
flip-flop is controlled by a common clock (CPc), as well as
its own clock pulse (CPn). The resultant clock signal
controlling the flip-flop is the logical OR operation of these
two clock signals. Data enters the master when both CPc
and CPn are LOW and enters the slave on the rising edge
of either CPc or CPn (or both).
Additional control signals include Master Set (MS) and
Master Reset (MR) inputs. Each flip-flop also has its own
Direct Set (SDn) and Direct Clear (CDn) signals. The MR,
MS, SDn and DCn signals override the clock signals. The
inputs on this device have 75KΩ pull-down resistors.
