DESCRIPTION
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 (CP
c
), as well as
its own clock pulse (CP
n
). The resultant clock signal
controlling the flip-flop is the logical OR operation of these
two clock signals. Data enters the master when both CP
c
and CP
n
are LOW and enters the slave on the rising edge
of either CP
c
or CP
n
(or both).
Additional control signals include Master Set (MS) and
Master Reset (MR) inputs. Each flip-flop also has its own
Direct Set (SD
n
) and Direct Clear (CD
n
) signals. The MR,
MS, SD
n
and DC
n
signals override the clock signals. The
inputs on this device have 75KΩ pull-down resistors.
