Frequently Asked Questions
What is the counting direction and stage count of the CD4521BEE4?
The CD4521BEE4 is a 24-stage binary UP counter. It provides outputs from the last 7 stages, allowing division ratios from 2^18 to 2^24, making it suitable for long-period timing and frequency division applications.
What is the load capacitance specification for CD4521BEE4?
The CD4521BEE4 is rated for a load capacitance (CL) of 50 pF. This specification is important when driving PCB traces or multiple inputs, as exceeding it can reduce switching speed and increase propagation delay.
What package does the CD4521BEE4 use and is it RoHS compliant?
The CD4521BEE4 comes in a DIP-16 (R-PDIP-T16) through-hole package, which simplifies hand soldering and prototyping. It carries the e4 JEDEC-609 code indicating it is lead-free (Pb-free) and RoHS compliant.
Can the CD4521BEE4 replace other 4000-series counters?
The CD4521BEE4 is part of the 4000/14000/40000 CMOS logic family, so it can be used alongside or as a drop-in replacement for compatible 24-stage binary counters in the same family, provided supply voltage and pinout match the application requirements.
