On each rising edge of the clock, the data at the D input is transferred to the Q output. The asynchronous set and reset override the clocked operation: S=1 forces Q=1, R=1 forces Q=0. The CD4013 is the CMOS equivalent of the TTL 7474, with the advantage of 3V-18V supply range and near-zero static power consumption, making it ideal for battery-powered and low-voltage applications. In toggle mode (D connected to NOT-Q), the CD4013 divides the clock frequency by 2. A single CD4013 can implement a switch debounce circuit (D=1, CLK=button, R=reset), or a set-reset latch (using the S and R inputs without clock). The BE suffix denotes the PDIP-14 package with full temperature range.","working_principle":"The CD4013BE D-type flip-flop captures the value at the D input on the rising edge of the clock and holds it at Q until the next rising edge. The truth table: CLK rising edge with D=0 \u2192 Q=0; CLK rising edge with D=1 \u2192 Q=1. When CLK is not rising, Q holds its value regardless of D. The asynchronous inputs override the clock: when S=HIGH, Q=1 immediately (regardless of CLK and D); when R=HIGH, Q=0 immediately. When both S and R are HIGH, both Q and NOT-Q go HIGH (invalid state); the final state after both are released is indeterminate. For normal clocked operation, S and R must both be LOW. For toggle mode: connect NOT-Q to D; each rising clock edge toggles Q, dividing the clock by 2. For a data latch: D receives data, CLK rising edge captures it. For debounce: D=VDD, CLK=switch through RC filter (R=100k\u03a9, C=0.1\u00b5F), R=reset button; the RC filter ensures only one clean edge reaches CLK.","pin_description":"\n

        CD4013 is the CMOS 4000-series dual d-type flip-flop operating over the wide 3-18V supply range. The HEF4013 (NXP) and MC144013 (onsemi) are direct pin-compatible equivalents. For higher speed at the cost of narrower voltage range, the 74HC74 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\/7973","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=7973"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/7973\/revisions"}],"predecessor-version":[{"id":8162,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/7973\/revisions\/8162"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=7973"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=7973"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=7973"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=7973"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
