CD4043 IC Quad NOR R/S Latch with 3-State Outputs

CD4043 IC Quad NOR R/S Latch with 3-State Outputs

The CD4043 IC is a CMOS quad cross-coupled NOR R/S latch with 3-state outputs. It contains four independently controlled latches, each providing separate SET and RESET inputs along with a dedicated Q output. A common ENABLE input allows simultaneous control of all latch outputs, supporting direct bus interface without the need for additional components.

Features:

• Wide supply voltage range: 3V to 15V
• Low power: 100 nW (typ.)
• High noise immunity: 0.45 VDD (typ.)
• Separate SET and RESET inputs for each latch
• NOR and NAND configuration
• 3-STATE output with common output enable
