Frequently Asked Questions
What counting direction does the CD4522BPW use, and can the starting count be preset?
The CD4522BPW counts in the down direction from a preset value to zero. Its load/preset input allows the counter to be initialized to any decade value synchronously, enabling precise control over the divide ratio in frequency division and programmable timer applications with 10-count resolution.
What load capacitance is the CD4522BPW rated for, and how does this affect fan-out in digital systems?
The CD4522BPW is rated for a 50 pF load capacitance at its outputs, which supports standard CMOS fan-out driving typical gate inputs in 4000-series circuits. This capacitance rating ensures predictable timing margins in counting and frequency division chains without requiring external buffer amplification.
In which package does the CD4522BPW ship, and how does it fit compact PCB layouts?
The CD4522BPW is packaged in a 16-pin TSSOP with a lead pitch of 0.65 mm, significantly smaller than the equivalent 16-pin DIP. This compact outline reduces board area by approximately 60% compared to through-hole alternatives, making it ideal for SMD-only production lines in modern industrial and consumer electronics.
