DESCRIPTION
The SY10/100E131 are high-speed quad master slave
D-type flip-flops with differential outputs designed for use
in new, high-performance ECL systems. The flip-flops may
be individually clocked by holding C
C
(Common Clock) at
a logic LOW and then using the four individual CE (Clock
Enable CE
0
–CE
3
) inputs to accomplish such clocking.
Alternatively, all four flip-flops can be clocked in common
by holding the CE inputs LOW and then using C
C
to clock
the data. In the common clock mode, the CE input acts as
a control that passes the C
C
signal to the flip-flop. Data is
clocked into the flip-flop on the rising edge of the output of
the logical OR operation between CE and C
C
(data enters
the master when both C
C
and CE are LOW and data
transfers to the slave when either CE or C
C,
or both, go
HIGH).
Asynchronous set and reset controls are provided. The
reset controls are individual and the set controls are
pairwise.
