詳細說明
3-Digit BCD CounterThe MC14553B 3–digit BCD counter consists of 3 negative edgetriggered BCDcounters that are cascadedsynchronously. A quad latch at the output of each counter permits storage of any given count. The information is then time division multiplexed, providingone BCD number or digit at a time. Digit select outputs provide display control. All outputs are TTL compatible. An on–chip oscillator provides the low–frequency scanning clock which drives the multiplexer output selector. This device is used in instrumentation counters,clock displays, digital panel meters, and as a building block for general logic applications.• TTL Compatible Outputs • On–Chip Oscillator • Cascadable • Clock Disable Input • Pulse Shaping Permits Very Slow Rise Times on Input Clock • Output Latches • Master Reset
主要特徵
- The LM324 is a monolithic operational amplifier

常見問題解答
What is MC14553BCP?
The MC14553BCP is a 3-digit BCD counter integrated circuit (IC) designed by ON Semiconductor. It is commonly used in electronic systems for frequency division, time delay generation, and counter applications.
How Does MC14553BCP Work?
The MC14553BCP functions as a 3-digit BCD counter, which can count in BCD (Binary Coded Decimal) format from 0 to 999. It has control inputs to enable counting, resetting, and other operations. The IC can be configured for various counting and timing applications through external control logic.
How Many Pins does MC14553BCP have and What are the Functions of the Pinout Configuration?
The MC14553BCP is housed in a 16-pin DIP (Dual Inline Package) package. The pinout configuration includes:
- VCC: Positive power supply pin.
- GND: Ground pin.
- RCIN, ENT, LAM: Control inputs for counting, enabling, and latching signals.
- BCD Out: Binary Coded Decimal output pins.
- Qc, Qb, Qa: Counter outputs for the units, tens, and hundreds places, respectively.
- CLK, RST, EO, BI, P, S0, S1, S2: Clock, reset, enable, blanking, and select inputs for control and configuration.
What are the Pros and Cons of MC14553BCP?
Pros:
- BCD Counter: Suitable for BCD counting applications, eliminating the need for external BCD to 7-segment decoder.
- Internal Latch: Includes an internal latching mechanism for easy parallel loading of BCD data.
- Simple Interface: Can be interfaced with microcontrollers or other digital ICs for control and synchronization.
- Wide Operating Voltage Range: Can operate over a wide voltage range, making it suitable for various power supply configurations.
Cons:
- Limited Count Range: The MC14553BCP is designed for 3-digit BCD counting, and may not be suitable for applications requiring higher count ranges.
- Complexity: Requires understanding of BCD counting and control logic for proper usage.
- Obsolete: Being an older IC, availability may be limited and long-term support may be a concern.
Are There Any Equivalents/Alternatives to MC14553BCP for Recommendation?
- The CD4518 from Texas Instruments is a similar dual BCD up-counter IC that can be considered as an alternative.
- Alternatives to the MC14553BCP include the HEF4518 from Nexperia and the HCF4518 from STMicroelectronics.
