CD4044 SOP Quad R/S Latch with Active Low Set And Reset Input (3-State)

Product Description: CD4044 SOP Quad R/S Latch with Active Low Set And Reset Input (3-State)

The CD4044 SOP Quad R/S Latch with Active Low Set and Reset Input (3-State) is a CMOS-based integrated circuit that contains four independent R/S (Reset-Set) latches with 3-state outputs. The key feature of the CD4044 is the active-low control inputs for Set (S) and Reset (R). These inputs are activated when driven low, making this latch ideal for use in systems where active-low logic is required.

Each latch can be independently controlled with its Set (S) and Reset (R) inputs, and the outputs are in 3-state mode (high, low, or high-impedance) based on the control inputs. The high-impedance state allows the latch to be effectively disconnected from the circuit when not in use, which is perfect for applications where multiple devices share the same bus or output lines.

Built with CMOS technology, the CD4044 offers low power consumption, high noise immunity, and fast switching speeds, making it an excellent choice for space-efficient, low-power digital circuits. It is available in a SOP-14 surface-mount package, making it suitable for modern PCB designs that demand compact form factors.

Key Features:

• Quad R/S Latches with Active Low Inputs: The CD4044 contains four independent R/S latches, each with active-low Set and Reset inputs. The outputs are controlled by the low logic levels of the inputs.
• 3-State Outputs: Each latch in the CD4044 features 3-state outputs that can be driven high, low, or placed in a high-impedance state (Hi-Z). The high-impedance state is used to disconnect the latch from the output circuit, making it ideal for multiplexing and bus systems.
• CMOS Technology: The IC is built using CMOS (Complementary Metal-Oxide-Semiconductor) technology, ensuring low power consumption, high noise immunity, and fast response times.
• Wide Voltage Range: The CD4044 operates within a voltage range of 3V to 18V, making it compatible with both low-voltage and standard logic systems.
• Compact SOP-14 Package: The SOP-14 surface-mount package is designed for space-saving, compact PCB layouts and is suitable for automated assembly processes in modern electronics manufacturing.
• Independent Latches: Each of the four latches in the CD4044 operates independently, which makes it flexible for use in multi-channel and multi-bit storage applications.

Applications:

• Data Storage and Latching: The CD4044 is used in data latching applications where binary data needs to be stored temporarily, such as in digital registers, shift registers, or memory circuits.
• Bus Systems and Multiplexing: The 3-state outputs make the CD4044 ideal for use in bus systems or multiplexers, where the outputs can be disabled (Hi-Z state) to prevent conflicts on shared data lines.
• Control Systems: It can be used in control systems where data needs to be latched and held in a particular state to trigger specific actions, such as in sequential logic, timing circuits, and event-driven systems.
• Signal Buffers: The 3-state outputs can also function as tri-state buffers, providing flexibility in digital circuits where the latch output must be disconnected or isolated from the circuit at times.
• Timing and Sequencing Circuits: The R/S latch is a fundamental component for sequential logic in timing and sequencing circuits, used in state machines or clock-driven processes.
• State Machines and Flip-Flops: The CD4044 can be integrated into state machines or flip-flop circuits to store intermediate values or maintain specific states in digital systems.
• Multiplexing Applications: In systems that require multiple outputs, the CD4044 can be used in multiplexing applications, where multiple latches need to be activated or deactivated depending on control signals.
