Details
CD4026B and CD4033B are both built with a 5-stage Johnson decade counter, and they also come with an output decoder. This decoder effectively converts Johnson code to a 7-segment decoded output, making it a great fit for driving stages in a numerical display. Both devices are particularly beneficial for display applications where there is a need for low power dissipation and/or a low package count. The inputs common to both include CLOCK, RESET, & CLOCK INHIBIT, along with common outputs like CARRY OUT and the seven decoded outputs (a, b, c, d, e, f, g). Additionally, The CD4026B has additional inputs and outputs, including a DISPLAY ENABLE input and DISPLAY ENABLE and UNGATED "C-SEGMENT" outputs. On the other hand, The CD4033B comes with more signals such as RIPPLE-BLANKING INPUT AND LAMP TEST INPUT and a RIPPLE-BLANKING OUTPUT

FAQs
What is CD4033BE?
The CD4033BE is a CMOS decade counter/divider IC (integrated circuit) designed by Texas Instruments. It is commonly used in electronic circuits for frequency division, time measurement, and sequential counting applications.
How Does CD4033BE Work?
The CD4033BE works by sequentially counting input clock pulses and dividing the frequency by 10. It can also drive common-cathode 7-segment displays, making it suitable for digital counter and display applications. The IC features a ripple carry output for cascading multiple counters, enabling extended counting capabilities.
How Many Pins does CD4033BE have and What are the Functions of the Pinout Configuration?
The CD4033BE is housed in a 16-pin DIP (Dual Inline Package) package. The pinout configuration includes:
- MR (Master Reset): Resets the counter when a high logic level is applied.
- CP (Clock Pulse): Input clock pulse for counting.
- TC (Terminal Count): Output signal indicating the count of 9 is reached.
- QA, QB, QC, QD (Outputs 0-3): Binary count outputs.
- CD (Carry Out): Ripple carry output for cascading multiple counters.
- VDD, VSS: Power supply pins.
- RO (Reset Output): Output signal indicating the counter has been reset.
What are the Pros and Cons of CD4033BE?
Pros:
- Simple to Use: Straightforward implementation for decade counting and frequency division.
- Drive 7-Segment Displays: Capable of directly driving common-cathode 7-segment displays for visual output.
- Ripple Carry Output: Allows cascading for extended counting applications.
- Low Power Consumption: Operates with low power, suitable for battery-operated systems.
Cons:
- Limited Counting Range: Limited to a decade counting range, may not be suitable for higher counting applications.
- External Components: May require additional components for debouncing and clock signal conditioning in some applications.
- Obsolete: As a CMOS IC, it may face obsolescence issues in the long term.
Are There Any Equivalents/Alternatives to CD4033BE for Recommendation?
Some alternatives to the CD4033BE include the HEF4033B from NXP Semiconductors and the HCF4033B from STMicroelectronics. These are functionally similar decade counters/dividers that can be used as substitutes in various electronic circuits.
