DESCRIPTION

The M54/74HC77 is a high speed CMOS 4-BIT D­TYPELATCHfabricated in silicongateC2MOStech­nology. It has the samehigh speed performance of
LSTTL combined with true CMOS low power con­sumption.It contains twogroups of 2-bit latches con­trolled by an enable input (G1• 2orG3•4). These
twolatch groups canbeusedindifferent circuits.The
dataapplied tothedata inputs(1D,2D,or3D,4D)are
transfered to the Q outputs (1Q,2Q, or 3Q, 4Q) re­spectively whentheenable input(G1 • 2orG3•4) is
takenhigh. The Q outputs will follow thedata inputs
aslong astheenableinputiskepthigh.Whenthe en­ableinput istaken low, theinformation dataapplied to
thedatainputs is retainedat theQ outputs. All inputs
areequipped withprotectioncircuitsagainst staticdis­charge andtransient excess voltage.
