CD4043 SOP CMOS Quad 3-State R-S Latch

Product Description: CD4043 SOP CMOS Quad 3-State R-S Latch

The CD4043 SOP CMOS Quad 3-State R-S Latch is a CMOS-based integrated circuit that provides four independent R-S (Reset-Set) latches, each with a 3-state output. This means that each of the four latches in the IC has three possible output states: high, low, or high impedance (Hi-Z). The 3-state feature makes the CD4043 ideal for applications where the latch needs to be disconnected from the circuit during certain conditions, such as in bus systems, multiplexers, or tri-state buffers.

The R-S latch is a simple form of bistable multivibrator that stores a binary state based on the Set (S) and Reset (R) inputs. When the Set input is activated, the latch outputs a high signal, and when the Reset input is activated, the latch outputs a low signal. If both inputs are inactive, the latch holds its last state.

The CD4043 is built with CMOS technology, which ensures low power consumption, high noise immunity, and fast switching speeds, making it ideal for a wide range of digital applications. The SOP-14 package is suitable for surface-mount applications, providing space-saving benefits for modern PCB designs.

Key Features:

• Quad 3-State R-S Latches: The CD4043 includes four independent R-S latches with 3-state outputs. Each latch can be individually controlled with Set and Reset inputs, allowing for flexible data storage and control in digital circuits.
• 3-State Outputs: Each latch has three possible output states: high, low, or high impedance (Hi-Z). The Hi-Z state allows the latch to be disconnected from the circuit, making it ideal for bus systems or tri-state buffers.
• CMOS Technology: Built with CMOS (Complementary Metal-Oxide-Semiconductor) technology, the CD4043 offers low power consumption, high speed, and high noise immunity, making it perfect for energy-efficient and reliable digital circuits.
• Wide Voltage Range: The IC operates across a voltage range of 3V to 18V, offering compatibility with a variety of low-voltage and standard logic systems.
• SOP-14 Package: The IC is available in a SOP-14 surface-mount package, designed for compact, space-efficient PCB designs, ideal for modern electronic manufacturing processes.
• Independently Controlled Latches: The four latches in the CD4043 are independently controlled, making it flexible for multi-channel storage applications.

Applications:

• Data Latching and Storage: The CD4043 is widely used in data storage and data latching applications where a binary state needs to be stored temporarily, such as in digital registers, shift registers, or memory systems.
• Bus Systems and Multiplexers: Due to its 3-state outputs, the CD4043 is ideal for use in bus systems and multiplexers, where the latch can be disabled (Hi-Z state) to avoid conflicts on shared lines or data buses.
• Control Systems: The IC is commonly used in control systems where data must be latched and later used to control outputs or trigger events.
• Clocked Storage in Sequential Logic Circuits: The R-S latch is a fundamental building block of sequential logic circuits. It can be used in timing circuits, state machines, or sequence control applications where specific binary states are required.
• Tri-State Buffers: In systems requiring tri-state buffers, the CD4043 can be employed to buffer signals while allowing for easy disconnection when necessary (Hi-Z state), preventing signal interference.
• Industrial Automation: The CD4043 can be found in industrial control systems for synchronization, data latching, and state holding in large digital systems.
• Memory and Timing Circuits: The R-S latch is essential for simple memory storage or timing functions, where data must be held stable for a specific duration or until a trigger condition is met.
