On each rising edge of the clock input, the counter advances one position, and the corresponding decoded output goes HIGH while all others remain LOW. The Johnson counter (twisted-ring) configuration ensures that only one output is active at a time and that the decoded outputs are spike-free, unlike binary counter + decoder combinations. The Schmitt trigger on the clock input provides pulse shaping, allowing unlimited clock rise and fall times\u2014no need for a clean square wave. The CLOCK INHIBIT pin (active HIGH) pauses counting without losing the current state. The RESET pin (active HIGH) immediately forces Q0 HIGH and all other outputs LOW. The CARRY-OUT signal completes one cycle every 10 clock pulses and serves as the clock input for the next stage in cascaded counter chains (divide-by-100, divide-by-1000, etc.). The E suffix denotes the PDIP-16 plastic through-hole package.","working_principle":"The CD4017BE uses a 5-stage Johnson (twisted-ring) counter where the complement of the last stage output is fed back to the first stage input. In a 5-stage Johnson counter, the count sequence is: 00000, 10000, 11000, 11100, 11110, 11111, 01111, 00111, 00011, 00001, then back to 00000 \u2014 producing 10 unique states. Each of these 10 states is decoded by simple 2-input AND gates to produce the Q0-Q9 outputs. The Johnson configuration guarantees that only one decoded output is HIGH at any time, and the outputs transition cleanly without spikes. On each rising clock edge (when CLOCK INHIBIT is LOW), the counter advances to the next state. The CARRY-OUT output goes HIGH for the first 5 clock cycles (Q0-Q4 active) and LOW for the next 5 cycles (Q5-Q9 active), providing a symmetrical 50% duty cycle output at 1\/10th the clock frequency. When cascading, CARRY-OUT of the first counter connects to the CLOCK input of the second counter, creating a divide-by-100 counter. The RESET pin forces all stages to 00000, making Q0 HIGH. Anti-lock gating prevents the counter from entering any of the 22 invalid states (out of 32 possible) that are not part of the normal counting sequence.","pin_description":"\n

        CD4017 is the CMOS 4000-series decade counter\/divider with decoded output operating over the wide 3-18V supply range. The HEF4017 (NXP) and MC144017 (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\/zh\/wp-json\/wp\/v2\/posts\/7901","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=7901"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/7901\/revisions"}],"predecessor-version":[{"id":8201,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/7901\/revisions\/8201"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=7901"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=7901"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=7901"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=7901"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
