It is the octal version of the CD4017 (which divides by 10), using a 4-stage Johnson counter to produce 8 sequential states. On each rising clock edge (when EN is LOW), the active output advances from Q0 to Q1 to Q2...Q7 and back to Q0. Only one output is HIGH at any time, producing a clean one-of-eight selection without the glitches common in ripple counters. The carry output (Q4, pin 12) provides a pulse every 8 clock cycles, useful for cascading to the next counter. The Schmitt trigger clock input allows very slow clock edges (like RC oscillators). The enable input (EN, active-LOW) can gate the clock: EN=LOW = count, EN=HIGH = hold. The reset input (RST, active-HIGH) clears the counter to Q0. Two CD4022s can be cascaded for divide-by-64 (8\u00d78). The BE suffix denotes the PDIP-16 package.","working_principle":"The CD4022BE uses a 4-stage Johnson counter (twisted-ring counter) to generate 8 sequential states. The Johnson counter feeds back the complement of the last stage to the first: starting from 0000, the sequence is 0000\u21921000\u21921100\u21921110\u21921111\u21920111\u21920011\u21920001\u21920000 (8 states). A decoder converts these 8 states into 8 one-active-HIGH outputs (Q0-Q7). Because the Johnson counter changes only one bit per clock, the decoded outputs are glitch-free (no momentary spikes during transitions). The clock advances the counter on the rising edge only when EN is LOW. When EN is HIGH, the clock is ignored and the counter holds. The RST input (HIGH) forces Q0=HIGH and all other outputs LOW. The carry output (Q4) is HIGH during states 0-3 and LOW during states 4-7; it produces a square wave at 1\/8 the clock frequency, suitable for cascading to the next CD4022's clock input. For cascading: Q4 of first CD4022 \u2192 CLK of second CD4022; each CD4022 divides by 8; total division = 8\u00d78 = 64.","pin_description":"\n

        CD4022 is the CMOS 4000-series divide-by-8 counter\/decoder operating over the wide 3-18V supply range. The HEF4022 (NXP) and MC144022 (onsemi) are direct pin-compatible equivalents. For higher speed at the cost of narrower voltage range, the 74HC4017 HC\/HCT families offer significantly faster propagation delay and lower power consumption at 2-6V. Surface-mount versions use the BM\/M suffix (SOIC); through-hole versions use the BE suffix (DIP).<\/p>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/8009","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=8009"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/8009\/revisions"}],"predecessor-version":[{"id":8130,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/8009\/revisions\/8130"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=8009"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=8009"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=8009"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=8009"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
