常見問題解答

What is MC14021BCP?

The MC14021BCP is a 24-stage binary counter with a divide-by-8 and a divide-by-16 counter. It is a CMOS integrated circuit designed by ON Semiconductor. The device is commonly used in frequency division and time measurement applications.

How Does MC14021BCP Work?

The MC14021BCP operates by counting input clock pulses and dividing the frequency by 8 and 16 sequentially. It features a ripple-carry output for cascading multiple counters and a carry-out for synchronization with other devices. The counter provides binary coded outputs for different stages of the count.

How Many Pins does MC14021BCP have and What are the Functions of the Pinout Configuration?

The MC14021BCP is housed in a 16-pin PDIP (Plastic Dual In-Line Package) package. The pinout configuration includes:

  • MR: Master reset input pin.
  • CP0-CP3: Clock pulse input pins.
  • Q0-Q3: Binary coded output pins for divide-by-8 counter.
  • Q4-Q7: Binary coded output pins for divide-by-16 counter.
  • CO: Carry-out pin for cascading multiple counters.
  • GND: Ground pin.
  • VDD: Power supply pin.

What are the Pros and Cons of MC14021BCP?

Pros:

  • Frequency Division: Provides divide-by-8 and divide-by-16 counting capabilities.
  • Simple Operation: Easy to use for basic frequency division tasks.
  • Cascading Ability: Supports cascading multiple counters for extended counting ranges.
  • CMOS Technology: Low power consumption and high noise immunity.
  • Reliable Performance: Stable operation in various frequency division applications.

Cons:

  • Limited Features: Basic functionality suited for simple counting tasks.
  • Pin Count: May require additional components for more complex operations.

Are There Any Equivalents/Alternatives to MC14021BCP for Recommendation?

  • The CD4024 from Texas Instruments is a similar 7-stage binary counter that can be considered as an alternative to the MC14021BCP.
  • Alternatives to the MC14021BCP include the 74HC4040 from NXP Semiconductors and the HCF4024B from STMicroelectronics.
