Overview

HD74HC279 Quad.
S–R Latches Description The latch is ideally suited for use as temporary stage for binary information processing and input/output units.
When either S or R is low, output is dependent on R input.
When both inputs are high, Output is stored before the indicated steady-state input conditions were established.
And when both inputs are low, output is high, but this high level are uncontinuance, if either of input goes high.
Features • • • • • High Speed Operation: tpd (S to Q) = 10 ns typ (CL = 50 pF) High Output Current: Fanout of 10 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 2 µA max (Ta = 25°C) ...
