Each gate implements Y = A \u2295 B = A\u0304B + AB\u0304; the output is HIGH when the two inputs are different, and LOW when they are the same. The XOR function is fundamental in digital logic: it is the building block for parity generation, binary addition, and comparison circuits. A key property of the XOR gate is its use as a true\/complement element: when one input is LOW, the output equals the other input (pass-through); when one input is HIGH, the output is the complement of the other input (inversion). This makes the XOR gate a controllable inverter\/buffer \u2014 useful for signal polarity switching and modulator circuits. The CD4030 is the original CMOS XOR gate; the CD4070 is a newer equivalent with identical functionality. The BE suffix denotes the PDIP-14 package.","working_principle":"Each XOR gate in the CD4030BE performs Y = A \u2295 B. Truth table: A=0,B=0 \u2192 Y=0; A=0,B=1 \u2192 Y=1; A=1,B=0 \u2192 Y=1; A=1,B=1 \u2192 Y=0. The output is HIGH when exactly one input is HIGH (odd parity). As a true\/complement element: when B=0, Y=A (pass); when B=1, Y=A\u0304 (invert). B acts as a polarity control. For parity generation: cascade XOR gates \u2014 Y1 = A\u2295B, Y2 = Y1\u2295C, Y3 = Y2\u2295D; Y3 = A\u2295B\u2295C\u2295D (even parity of 4 bits). For binary addition: Sum = A\u2295B, Carry = A\u00b7B; two XOR gates plus an AND gate form a half-adder. For comparison: A\u2295B = 0 when A=B, 1 when A\u2260B; OR multiple XOR outputs for multi-bit inequality detection. The CD4030 and CD4070 have the same function; the CD4030 is the original Harris design and the CD4070 is the TI redesign, both are interchangeable.","pin_description":"\n

        CD4030 is the CMOS 4000-series quad 2-input exclusive-or gate operating over the wide 3-18V supply range. The HEF4030 (NXP) and MC144030 (onsemi) are direct pin-compatible equivalents. For higher speed at the cost of narrower voltage range, the 74HC86 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\/8007","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=8007"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/8007\/revisions"}],"predecessor-version":[{"id":8132,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/8007\/revisions\/8132"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=8007"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=8007"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=8007"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=8007"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
