Unlike the CD4060 (which has an integrated oscillator but hides Q1-Q3), the CD4040 has no oscillator but provides every output from Q1 (\u00f72) through Q12 (\u00f74096). This makes the CD4040 more flexible when all division ratios are needed or when the clock source is external (from a microcontroller, crystal oscillator module, or another counter). The maximum division is 2^12 = 4096. Two CD4040s can be cascaded for 24-bit counting (\u00f72 to \u00f716,777,216) by connecting Q12 of the first to the CLK of the second. The counter advances on the negative-going transition of the clock input. The master reset (MR=HIGH) clears all stages asynchronously. The Schmitt trigger on the clock input allows very slow clock edges. At 5V, the CD4040 can count up to about 3MHz, making it suitable for audio-range frequency division. The BE suffix denotes the PDIP-16 package.","working_principle":"The CD4040BE consists of 12 master-slave flip-flops connected as a binary ripple counter. Each flip-flop divides its input by 2. The clock input (CLK) drives the first flip-flop (Q1), Q1 drives Q2, Q2 drives Q3, and so on to Q12. The counter advances on the HIGH-to-LOW (negative-going) transition of the clock. Starting from all zeros, the outputs sequence through all 4096 combinations (000000000000 to 111111111111) before rolling over. The reset input (MR) is asynchronous: when MR=HIGH, all outputs are forced to 0 immediately, regardless of the clock state. For normal counting, MR must be LOW. Because it's a ripple counter, the outputs don't change simultaneously \u2014 Q2 changes after Q1, Q3 after Q2, etc., with a propagation delay of about 16ns per stage at 10V. This means decoded outputs can have glitches and shouldn't be used as clocks for other synchronous logic. For frequency division, the output at Qn is a square wave at f_CLK\/2^n. For cascading: Q12 of the first CD4040 connects to CLK of the second; the second counter increments each time the first rolls over from 4095 to 0.","pin_description":"\n

        CD4040 is the CMOS 4000-series 12-stage ripple-carry counter operating over the wide 3-18V supply range. The HEF4040 (NXP) and MC144040 (onsemi) are direct pin-compatible equivalents. For higher speed at the cost of narrower voltage range, the 74HC4040 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\/7991","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=7991"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/7991\/revisions"}],"predecessor-version":[{"id":8147,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/7991\/revisions\/8147"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=7991"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=7991"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=7991"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=7991"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
