It combines four features that are rare to find in a single package: (1) Up\/down counting \u2014 the UP\/DOWN pin selects whether the counter increments or decrements on each clock edge. (2) Binary or decade mode \u2014 the BINARY\/DECADE pin selects between 4-bit binary (0-15) and BCD decade (0-9) counting. (3) Preset capability \u2014 the JAM inputs (J1-J4) allow the counter to be loaded with any value asynchronously when PRESET ENABLE is HIGH. (4) Look-ahead carry \u2014 the CARRY OUT signal goes LOW one clock before the terminal count, enabling high-speed synchronous cascading. This versatility makes the CD4029 ideal for applications like event counters that increment and decrement, programmable dividers, and A\/D converter stages. The BE suffix denotes the PDIP-16 package with full military temperature range (-55\u00b0C to +125\u00b0C).","working_principle":"The CD4029BE advances one count on the positive edge of the CLOCK when both CARRY-IN (active-LOW) and PRESET ENABLE are LOW. CARRY-IN acts as a clock enable: when HIGH, counting is inhibited. The BINARY\/DECADE input selects the counting mode: HIGH = binary (0\u219415), LOW = decade (0\u21949). The UP\/DOWN input selects direction: HIGH = count up, LOW = count down. In binary up mode, the counter sequences 0,1,2...14,15,0,1...; in decade up mode: 0,1,2...8,9,0,1...; in binary down mode: 15,14,13...1,0,15,14...; in decade down mode: 9,8,7...1,0,9,8... When PRESET ENABLE is HIGH, the JAM inputs (J1-J4) are asynchronously loaded into the counter \u2014 this allows starting from any value. J1 is the LSB, J4 is the MSB. The CARRY OUT signal is normally HIGH and goes LOW when: (a) counting up and the counter reaches its maximum (15 in binary, 9 in decade), OR (b) counting down and the counter reaches zero, provided CARRY-IN is LOW. This CARRY OUT connects to the CARRY-IN of the next stage for cascading. For synchronous (parallel) cascading, all chips share the same clock; each CARRY OUT feeds the next CARRY IN. For ripple cascading, each CARRY OUT connects to the next chip's CLOCK input.","pin_description":"\n

        CD4029 is the CMOS 4000-series up\/down binary\/decade counter operating over the wide 3-18V supply range. The HEF4029 (NXP) and MC144029 (onsemi) are direct pin-compatible equivalents. For higher speed at the cost of narrower voltage range, the 74HC192 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\/7966","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=7966"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/7966\/revisions"}],"predecessor-version":[{"id":8167,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/7966\/revisions\/8167"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=7966"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=7966"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=7966"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=7966"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
