CD4044BE CD4044 CMOS Quad NAND R/S Latch with 3-State O/P
Description: The CD4044B types are quad cross-coupled 3-state CMOS NAND 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. Included: CD4044BE This item features: 3-state outputs with common output ENABLE Separate SET and RESET inputs for each latch NOR and NAND configurations 5-V, 10-V, and 15-V parametric ratings Standardized symmetrical output characteristics 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 Noise margin (over full package temperature range): 1 V at VDD = 5 V 2 V at VDD = 10 V 2.5 V at VDD =
