Detailed Description:

The CD4028BE is a CMOS BCD (Binary-Coded Decimal) to Decimal Decoder / Demultiplexer IC with four input lines (A, B, C, D) and ten active-high outputs (Q0–Q9). It converts a 4-bit binary input to a corresponding decimal output, making it ideal for driving LEDs, displays, or selecting one of ten outputs based on binary input.

It operates over a wide voltage range (3V to 15V) and features low power consumption, high noise immunity, and compatibility with TTL logic. The DIP-16 form factor allows easy use on breadboards or PCBs.

Key Features:

• BCD (Binary-Coded Decimal) to Decimal decoding

• 4 input lines (A, B, C, D) → 10 output lines (Q0–Q9)

• High-level active outputs

• Operates with supply voltage from 3V to 15V

• DIP-16 package for breadboard/PCB use

• Low static power consumption

• TTL and CMOS logic compatible

• Wide operating temperature range

• Ideal for LED multiplexing and display control

Technical Specifications:

How to Use:

1. Connect Vdd (pin 16) to 5V (or up to 15V), and Vss (pin 8) to GND

2. Apply 4-bit binary input to A, B, C, D input pins

3. The corresponding Qn output pin will go HIGH, all others stay LOW

4. Use output to drive LEDs, transistors, or control logic

5. Perfect for digital counters, display multiplexing, and logic routing

Applications:

• 7-segment LED display control

• Digital counters and timers

• Memory address decoding

• Data routing in control systems

• Decimal digit selection

• Demultiplexing circuits

• Logic control units in embedded systems

Package Includes:

• 1 × CD4028BE BCD to Decimal Decoder IC – DIP-16
