Each register has its own DATA input, MR (master reset), and four parallel outputs (Q1-Q4). On each rising clock edge, the DATA input is shifted into Q1, and Q1\u2192Q2\u2192Q3\u2192Q4 in a ripple fashion. When MR is HIGH, all outputs are forced to 0 asynchronously. The common clock means both registers shift simultaneously \u2014 useful for dual-channel applications where two data streams must be synchronized. The two registers can also be cascaded: Q4 of register 1 connects to DATA of register 2, creating an 8-bit shift register. Unlike the CD4094, the CD4015 has no output latch \u2014 outputs change as data shifts through, which is fine for LED chasers but may cause flicker in display applications requiring stable outputs. The CD4015 is simpler and lower-cost than the CD4094 for applications that don't need latched outputs. The BE suffix denotes the PDIP-16 package.","working_principle":"Each 4-bit shift register in the CD4015BE operates as follows: on each rising CLK edge, DATA is loaded into Q1, and all other bits shift one position (Q1\u2192Q2, Q2\u2192Q3, Q3\u2192Q4). The old Q4 data is lost (or passed to a cascaded register). When MR (master reset) is HIGH, all four outputs (Q1-Q4) are forced to 0 immediately regardless of CLK and DATA. For normal shifting, MR must be LOW. To load 4 bits: shift 4 clock cycles with the desired data on DATA; after 4 clocks, Q1=last bit shifted, Q4=first bit shifted. For cascading: Q4 of register 1 \u2192 DATA of register 2; shared CLK; after 8 clocks, register 2 has the first 4 bits and register 1 has the last 4 bits \u2014 an 8-bit SIPO. Both registers shift on the same clock edge, so dual data streams can be processed in parallel. The CD4015 is essentially half a CD4014 (8-bit) with separate resets and no parallel load capability.","pin_description":"\n

        CD4015 is the CMOS 4000-series dual 4-bit serial-in\/parallel-out shift register operating over the wide 3-18V supply range. The HEF4015 (NXP) and MC144015 (onsemi) are direct pin-compatible equivalents. For higher speed at the cost of narrower voltage range, the 74HC164 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\/8001","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=8001"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/8001\/revisions"}],"predecessor-version":[{"id":8138,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/8001\/revisions\/8138"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=8001"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=8001"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=8001"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=8001"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
