Frequently Asked Questions
What is the CD4018BE and what does it do?
The CD4018BE is a CMOS presettable divide-by-N Johnson ring counter from Texas Instruments. It divides an input clock frequency by a programmable value N (2–10) configured through external connections. It features a load/preset input for synchronous initialization, operates with a 50pF load capacitance, and counts in the up direction, making it ideal for frequency division and timing applications.
What package and supply voltage does the CD4018BE use?
The CD4018BE comes in a 16-pin dual-in-line package (PDIP), which is convenient for through-hole PCB assembly and breadboard prototyping. As a member of the CMOS 4000/14000/40000 family, it supports a wide supply voltage range (typically 3V to 18V), offering compatibility with both 5V TTL-level systems and higher-voltage industrial logic environments.
What are common applications for the CD4018BE?
Common applications include programmable frequency dividers, multi-phase clock generators, stepper motor sequencers, and digital timing circuits. The CD4018BE's Johnson counter architecture supports sequential output patterns useful in industrial control systems, telecommunications equipment, and test instrumentation. Its presettable feature allows synchronous initialization, which is valuable in systems requiring precise startup conditions.
Is there a drop-in replacement or alternative for the CD4018BE?
Yes, the CD4018BE is pin-compatible with other 4018-series CMOS ICs from manufacturers such as Motorola (MC14018), Fairchild, and ON Semiconductor. These alternatives share the same 16-pin DIP footprint, identical logic function, and comparable electrical characteristics, allowing direct substitution in most designs without PCB modifications.
