CD4043BC CD4044BC
Quad 3-STATE NOR R/S Latches
Quad 3-STATE NAND R/S Latches
General Description
The CD4043BC are quad cross-couple 3-STATE CMOS
NOR latches, and the CD4044BC are quad cross-couple 3-
STATE CMOS NAND latches. Each latch has a separate Q
output and individual SET and RESET inputs. There is a
common 3-STATE ENABLE input for all four latches. A
logic "1" on the ENABLE input connects the latch states to
the Q outputs. A logic "0" on the ENABLE input discon-
nects the latch states from the Q outputs resulting in an
open circuit condition on the Q output. The 3-STATE fea-
ture allows common bussing of the outputs.

Note 1: "Absolute Maximum Ratings" are those values beyond which the
safety of the device cannot be guaranteed; they are not meant to imply that
the devices should be operated at these limits. The tables of "Recom-
mended Operating Conditions" and "Electrical Characteristics" provide con-
ditions for actual device operation.
