FEATURES
6-BIT D
LATCH
The SY10/100E150 are 6-bit D latches with differential
outputs designed for use in new, high- performance ECL
systems. When both Latch Enables (LEN
1
, LEN
2
) are at a
logic LOW, the latch is in the transparent mode and input
data propagates through to the output. A logic HIGH on
either LEN
1
or LEN
2
(or both) latches the input data. The
Master Reset (MR) overrides all other signals to set the Q
outputs to a logic LOW.
