The SY10/100E151 offer 6 edge-triggered, high-speed,
master-slave D-type flip-flops with differential outputs,
designed for use in new, high-performance ECL systems.
The two external clock signals (CLK
1
, CLK
2
) are gated
through a logical OR operation before use as clocking
control for the flip-flops. Data is clocked into the flip-flops
on the rising edge of either CLK
1
or CLK
2
(or both). When
both CLK
1
and CLK
2
are at a logic LOW, data enters the
master and is transferred to the slave when either CLK
1
or
CLK
2
(or both) go HIGH.
The MR (Master Reset) signal operates asynchronously
to make all Q outputs go to a logic LOW.
