| Micrel, Inc. HEX D-LATCH SY100S350 SY100S350 FEATURES s s s s s s s s s s s Max. transparent propagation delay of 900ps Min. Master Reset and Enable pulse widths of 100ps IEE min. of -98mA Industry standard 100K ECL levels Extended supply voltage option: VEE = -4.2V to -5.5V Voltage and temperature compensation for improved noise immunity Internal 75K input pull-down resistors More than 40% faster than Fairchild Approximately 30% lower power than Fairchild Function and pinout compatible with Fairchild F100K Available in 24-pin CERPACK and 28-pin PLCC packages DESCRIPTION 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 75K pull-down resistors.
