CD4043 Quad NOR R-S Latch Tri-state
Package SOIC, PDIP, SOP Series CD4000 (CMOS)
CD4043 overview
CD4043 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC's) constructed with N- and P-channel enhancement mode transistors. CD4043 has Quad NOR R-S Latch Tri-state
CD4043 has a supply voltage range of 5V to 20V, which is much higher than any contemporary logic family. It has buffered output which improves transfer characteristics by providing very high gain. All inputs are protected against static discharge with diodes to VDD and VSS.
