  • The CD4043B types are quad cross-coupled 3-state CMOS NOR latches. Each latch has a separate Q output and individual SET and RESET inputs.
  • 3-state outputs with common output ENABLE, 5-V, 10-V, and 15-V parametric ratings, Noise margin (over full package temperature range): 1 V at VDD = 5 V, 2 V at VDD = 10 V, 2.5 V at VDD = 15 V
  • Separate SET and RESET inputs for each latch, Standardized symmetrical output characteristics, Meets all requirements of JEDEC Tentative Standard No. 13B, "Standard Specifications for Description of 'B' Series CMOS Devices"
  • NOR and NAND configurations, 100% tested for quiescent current at 20 V, Maximum input current of 1 µA at 18 V over full package temperature range; 100 nA at 18 V and 25°C
  • Example Applications: Holding register in multi-register system, Four bits of independent storage with output ENABLE, Strobed register, General digital logic


The CD4043B types are quad cross-coupled 3-state CMOS NOR latches. Each latch has a separate Q output and individual SET and RESET inputs. The Q outputs are controlled by a common ENABLE input. A logic "1" or high on the ENABLE input connects the latch states to the Q outputs. A logic "0" or low on the ENABLE input disconnects the latch states from the Q outputs, resulting in an open circuit condition on the Q outputs. The open circuit feature allows common busing of the outputs.
