The SY10/100E154 offer five 2:1 multiplexers followed
by latches with differential outputs, designed for use in
new, high-performance ECL systems. The two external
Latch-Enable signals (LEN
1
, LEN
2
) are gated through a
logical OR operation before use as control for the five
latches. When both LEN
1
and LEN
2
are at a logic LOW, the
latches are transparent, thus presenting the data from the
multiplexers at the output pins. If either LEN
1
or LEN
2
(or
both) are at a logic HIGH, the outputs are latched.
The multiplexer operation is controlled by the SEL(Select)
signal which selects one of the two bits of input data at each
mux to be passed through.
The MR (Master Reset) signal operates asynchronously
to make all Q outputs go to a logic LOW.
