The SY100S350 offers six high-speed D-Latches with
both true and complement outputs, and is performance
compatible for use with high-performance ECL systems.
When both enable signals (Ea and Eb) are at a logic LOW,
the latches are transparent and the input signals( D0–D5)
appear at the outputs (Q0–Q5) after a propagation delay. If
either or both of the enable signals are at a logic HIGH, then
the latches store the last valid data present on its inputs
before Ea or Eb went to a logic HIGH. The Master Reset
(MR) overrides all other input signals and takes the outputs
to a logic LOW state. All inputs have 75kΩ pull-down
resistors.
