CD4028 SOP BCD to Decimal Decoder

Product Description: CD4028 SOP 1-of-10 Decoder

The CD4028 SOP 1-of-10 Decoder is a CMOS-based integrated circuit designed to perform 1-of-10 decimal decoding. This IC takes a 4-bit binary input and decodes it into a one-hot decimal output, which means that only one of the 10 output lines will be high, depending on the binary input. It is commonly used in decoding applications such as BCD-to-decimal conversion or controlling seven-segment displays in digital systems.

The CD4028 features 10 active low outputs (labeled Y0 through Y9) that are individually enabled based on the 4-bit input. The output corresponding to the binary value of the input will be driven low, while all other outputs will remain high. This type of binary-to-decimal decoding is ideal for applications like digital counters, displays, and multiplexers where decimal control is needed.

The IC also includes carry-out and strobe functions, making it suitable for cascading with other logic elements or for generating signals in control systems. With its wide voltage range and low power consumption, the CD4028 is ideal for low-voltage digital systems and energy-efficient designs.

Key Features:

• 1-of-10 Decimal Decoder: The CD4028 decodes a 4-bit binary input into a 1-of-10 output format, driving only one of the 10 output lines low at any time.
• 10 Active Low Outputs: The IC provides 10 output pins (Y0 to Y9), each corresponding to a specific decimal value (0 to 9). Only one output is low for each 4-bit input.
• Carry-Out Output: The carry-out (CO) pin indicates when a new output is selected, which is useful for cascading multiple decoders or triggering sequential events.
• Strobe Output: The strobe (STB) pin allows for controlled output activation, useful for multiplexing or control logic applications.
• Wide Voltage Range: The IC operates across a voltage range of 3V to 18V, providing compatibility with both low-voltage and standard logic systems.
• Low Power Consumption: Designed with CMOS technology, the CD4028 consumes minimal power, making it suitable for battery-operated devices or energy-efficient circuits.
• Compact SOP-16 Package: The IC comes in a SOP-16 surface-mount package, ideal for space-saving PCB designs and automated assembly.

Applications:

• BCD-to-Decimal Decoding: The CD4028 is frequently used in Binary-Coded Decimal (BCD) to decimal decoding, where a 4-bit BCD input is converted into a decimal output to drive displays or control logic.
• Seven-Segment Display Driver: The IC is commonly used in digital clocks, calculators, and other numeric displays to drive seven-segment displays. The output can control the selection of a particular segment, enabling numeric digit display.
• Frequency Division: The CD4028 can be used in frequency division circuits, where its ability to decode a 4-bit input into decimal values is used to control counters or generate specific output sequences.
• Multiplexing: The 1-of-10 output can be used in multiplexing applications to select specific data lines or signal paths in communication systems and control systems.
• Control Logic Circuits: The IC can be used in control systems where a specific output needs to be selected based on a binary input, such as in state machines or event-driven systems.
• Digital Counters: The CD4028 is perfect for digital counter applications, where it is used to decode the binary count into decimal form for control or display purposes.
• Sequencers and State Machines: The IC can be integrated into sequencers and state machines where a specific state or action is triggered based on a binary input.
