Details
The MC14518B dual BCD counter and the MC14520B dual binary counter are constructed with MOS P−channel and N−channel enhancement mode devices in a single monolithic structure. Each consists of two identical, independent, internally synchronous 4−stage counters. The counter stages are type D flip−flops, with interchangeable Clock and Enable lines for incrementing on either the positive−going or negative−going transition as required when cascading multiple stages. Each counter can be cleared by applying a high level on the Reset line. In addition, the MC14518B will count out of all undefined states within two clock periods. These complementary MOS up counters find primary use in multi−stage synchronous or ripple counting applications requiring low power dissipation and/or high noise immunity.Features• Diode Protection on All Inputs• Supply Voltage Range = 3.0 Vdc to 18 Vdc• Internally Synchronous for High Internal and External Speeds• Logic Edge−Clocked Design — Incremented on Positive Transition of Clock or Negative Transition on Enable• Capable of Driving Two Low−power TTL Loads or One Low−power Schottky TTL Load Over the Rated Temperature Range• Pb−Free Packages are Available*

FAQs
What is MC14518BCP?
The MC14518BCP is a dual binary up-counter IC (integrated circuit) designed by ON Semiconductor. It is commonly used in various digital counting and timing applications, such as frequency dividers, ripple counters, and clock generators.
How Does MC14518BCP Work?
The MC14518BCP operates as a dual 4-bit binary up-counter, counting up on the rising edge of the clock input. It can be cascaded to create higher count lengths and can be configured to enable or disable the counting operation. The IC is versatile and can be used in conjunction with other logic gates and components to create custom counting and timing solutions.
How Many Pins does MC14518BCP have and What are the Functions of the Pinout Configuration?
The MC14518BCP is housed in a 16-pin PDIP (Plastic Dual In-line Package) package. The pinout configuration includes:
- MR (Master Reset): Master reset pin for clearing the count.
- CP0, CP1: Clock input pins for counter 0 and counter 1, respectively.
- CNTEN (Count Enable): Count enable pin for enabling or disabling the counting operation.
- QA0-QD0, QA1-QD1: Output pins for the 4-bit binary counts of counter 0 and counter 1, respectively.
- VCC (Supply Voltage): Positive power supply pin.
- GND (Ground): Ground reference pin.
What are the Pros and Cons of MC14518BCP?
Pros:
- Dual Counter: Provides two 4-bit binary up-counters in a single IC.
- Versatile: Can be easily integrated into digital logic designs for various counting and timing applications.
- Simple Interface: Requires minimal external components for basic counting operations.
- Wide Operating Voltage Range: Supports a wide supply voltage range for versatile design compatibility.
Cons:
- Not Programmable: The counting behavior and modulus are fixed and not programmable.
- Limited Count Range: Suited for moderate count lengths and may require cascading for longer counts.
- Package Size: The 16-pin PDIP package may not be suitable for space-constrained designs.
Are There Any Equivalents/Alternatives to MC14518BCP for Recommendation?
- The CD4518 from Texas Instruments is a similar dual 4-bit up-counter IC that can be considered as an alternative.
- Alternatives to the MC14518BCP include the 74HC390 from Nexperia and the 40192B from ON Semiconductor.
