CD4043BC • CD4044BC Quad 3-STATE NOR R/S Latches • Quad 3-STATE NAND R/S Latches October 1987 Revised January 1999 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 3STATE 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 disconnects the latch states from the Q outputs resulting in an open circuit condition on the Q output.
The 3-STAT...
