Quad NOR R-S Latch Tri-state IC - CD4043

Quad NOR R-S Latch Tri-state IC - CD4043

The CD4x Series CD4043 IC is quad cross-coupled 3-STATE CMOS NOR latches These 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.

Pinout:

Applications:

• Multiple bus storage
• Strobed register
• Four bits of independent storage with output enable
• General digital logic
