Supply original CD4043BDR, Logic - Latches, by Texas Instruments

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 disconnects the latch states from the Q outputs resulting in an open circuit condition on the Q output.
The 3-STATE feature allows common bussing of the outputs.
