詳細說明
The CD4040BCN is a CMOS 12-stage binary counter that sets itself apart with its built-in oscillator and minimal external component requirements. With just an external resistor and capacitor, this device can be easily implemented into a variety of circuit designs. Its maximum clock frequency of 4 MHz allows for efficient counting, and the option to cascade multiple CD4040BCN counters enables longer count lengths for more complex applications
主要特徵
- Wide supply voltage range: 1.0V to 15V
- High noise immunity: 0.45 VDD (typ.)
- Low power TTL compatibility: Fan out of 2 driving 74L or 1 driving 74LS
- Medium speed operation: 8 MHz typ. at VDD = 10V
- Schmitt trigger clock input

常見問題解答
What is CD4040BCN?
The CD4040BCN is a 12-stage binary ripple counter with a wide operating voltage range, designed by Texas Instruments. It is commonly used in digital counting and timing applications, such as frequency dividers, event counters, and time-delay generators.
How Does CD4040BCN Work?
The CD4040BCN works by sequentially dividing the applied clock signal by 2^n, where n ranges from 1 to 12 according to the selected stage. This results in a binary ripple counter output that can be used for various time and frequency measurements and controls.
How Many Pins does CD4040BCN have and What are the Functions of the Pinout Configuration?
The CD4040BCN is housed in a 16-pin PDIP (Plastic Dual Inline Package) package. The pinout configuration includes:
- Q0-Q11: Output pins for the 12 counter stages.
- MR: Master reset input pin for clearing the counter.
- CP: Clock input pin for the counter.
- CD4040BCN: Serial interface control pins.
What are the Pros and Cons of CD4040BCN?
Pros:
- Wide Operating Voltage Range: Supports a broad range of input voltages for versatility.
- Easy to Use: Simple binary ripple counter functionality for straightforward applications.
- Multiple Counter Stages: Provides 12 counter stages for extended counting sequences.
- Cost-Effective: Offers cost-effective binary counter functionality for diverse applications.
Cons:
- CMOS Technology: May have limitations in high-speed applications compared to advanced counter technologies.
- Power Consumption: Relatively higher power consumption compared to more modern low-power logic devices.
Are There Any Equivalents/Alternatives to CD4040BCN for Recommendation?
- The HEF4040B from NXP Semiconductors is a similar 12-stage binary counter with comparable functionality.
- Alternatives to the CD4040BCN include the TC74HC4040AF from Toshiba and the HCF4040 from STMicroelectronics.
