CD4043B CMOS Quad 3-State NOR R/S Latches

Texas Instruments CD4043B CMOS Quad 3-State NOR R/S Latches are high-performance quad RS latches designed to deliver dependable data storage and control in digital electronics. Each of its four latches operates independently, making it ideal for applications requiring multiple data retention points. With 3-state outputs and compatibility across various voltages, the CD4043B offers flexibility and efficiency for both commercial and industrial designs. The CD4043B latches provide separate SET and RESET inputs for each latch, NOR and NAND configurations, and 5V, 10V, and 15V parametric ratings. These latches meet all requirements of JEDEC tentative standard No. 13B, "Standard Specifications for Description of 'B' Series CMOS Devices". Typical applications include memory storage elements, control systems, signal synchronization, and digital logic circuits.
