DESCRIPTION
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 (CLK1, CLK2) 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 CLK1 or CLK2 (or both). When
both CLK1 and CLK2 are at a logic LOW, data enters the
master and is transferred to the slave when either CLK1 or
CLK2 (or both) go HIGH.
The MR (Master Reset) signal operates asynchronously
to make all Q outputs go to a logic LOW.
