Unlike the CD4026 (which is a counter+decoder), the CD4511 only decodes \u2014 it doesn't count. This makes it suitable for use with external counters (CD4017, CD4029, 74LS90, or microcontroller BCD outputs). The 25mA output current per segment is sufficient to directly drive LEDs with appropriate current-limiting resistors (typically 220\u03a9-1k\u03a9 per segment at 5V). The latch stores the BCD value when LE goes HIGH, freezing the display while the input changes. The Lamp Test (LT, active LOW) turns all segments on simultaneously for display verification. The Blanking Input (BI, active LOW) turns all segments off for leading zero suppression or display multiplexing. Invalid BCD inputs (10-15) are automatically blanked. The BE suffix denotes the PDIP-16 package with full temperature range.","working_principle":"The CD4511BE has three functional blocks: (1) A 4-bit transparent latch controlled by LE: when LE is LOW, the latch is transparent (outputs follow inputs); when LE goes HIGH, the current BCD value is latched and held. (2) A BCD-to-7-segment decoder that converts the latched BCD value to 7-segment format. Digits 0-9 produce normal segment patterns; digits 10-15 (invalid BCD) produce blank output (all segments off). (3) An output driver that provides active-HIGH current-limited outputs capable of sourcing up to 25mA per segment. The three control inputs override the decoded output: LT (Lamp Test) activates all segments regardless of BCD input \u2014 used to check for burned-out LEDs. BI (Blanking Input) deactivates all segments \u2014 used for display blanking during multiplexing or for leading zero suppression. When both LT and BI are inactive (HIGH), the segment outputs follow the decoded BCD value. For leading zero suppression: connect the RBI of the most significant digit to GND; if that digit is 0, its segments are blanked AND its RBO goes LOW; connect this RBO to the next digit's RBI, causing cascading blanking of leading zeros. The 4511 does NOT have a Ripple Blanking Output (RBO) \u2014 for ripple blanking, use the CD4543 or handle it with external logic.","pin_description":"\n

        CD4511 is the CMOS 4000-series bcd-to-7-segment latch\/decoder\/driver operating over the wide 3-18V supply range. The HEF4511 (NXP) and MC144511 (onsemi) are direct pin-compatible equivalents. For higher speed at the cost of narrower voltage range, the 74HC4511 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\/es\/wp-json\/wp\/v2\/posts\/7960","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=7960"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7960\/revisions"}],"predecessor-version":[{"id":8172,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7960\/revisions\/8172"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=7960"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=7960"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=7960"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=7960"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
