HCF4518M013TR

Counter Dividers Overview

The HCF4518M013TR is a dual BCD up counter fabricated in Metal Oxide Semiconductor technology, available in SOP-16 packaging. It contains two identical internal four-stage counters utilizing D-type flip-flops with interchangeable clock and enable lines for positive or negative edge triggering. The device operates within a supply voltage range of 3V to 20V and supports synchronous internal carry propagation. Key electrical parameters include a maximum quiescent current of 3000µA at 20V, an input leakage current of ±1µA at 18V, and a typical propagation delay of 115ns at 10V.

Counter Dividers FAQ

How does the HCF4518M013TR handle counter incrementing?

The counters advance on either positive-going or negative-going transitions depending on the configuration of the interchangeable Clock and Enable lines.

What is the method for resetting the counters?

The counters are cleared by applying high levels to their respective Reset lines, which forces outputs Q1 through Q4 to zero.
