The LAT pin latches the shift register data to the output latch. When EN is active, the enabled output channels sink constant current through the connected LEDs. The current magnitude is set by an external resistor on the R-EXT pin. LED diagnostics compare expected vs actual output voltage to detect open or short conditions.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>2<\/td><td>SDI<\/td><td>Serial data input<\/td><\/tr><tr><td>3<\/td><td>SDO<\/td><td>Serial data output (cascade)<\/td><\/tr><tr><td>4<\/td><td>EN<\/td><td>Output enable (active low)<\/td><\/tr><tr><td>5<\/td><td>LAT<\/td><td>Data latch<\/td><\/tr><tr><td>6<\/td><td>SCLK<\/td><td>Serial clock<\/td><\/tr><tr><td>7<\/td><td>R-EXT<\/td><td>External current set resistor<\/td><\/tr><tr><td>8<\/td><td>VDD<\/td><td>Logic supply (3.3-5V)<\/td><\/tr><tr><td>9-24<\/td><td>OUT0-OUT15<\/td><td>Constant current sink outputs<\/td><\/tr><\/table>","application_scenarios":"<ul><li>LED display panel and video wall driver<\/li><li>LED signage and lighting control<\/li><li>LCD backlight driver array<\/li><li>Industrial LED indicator matrix<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Spec1<\/th><th>Spec2<\/th><\/tr><tr><td>MBI5168GNS-A<\/td><td>Macroblock<\/td><td>16-bit 3-90mA<\/td><td>No diagnostics<\/td><\/tr><tr><td>TLC59283DBQR<\/td><td>TI<\/td><td>16-bit 3-45mA<\/td><td>No diagnostics<\/td><\/tr><tr><td>STP16CP05MTR<\/td><td>STMicro<\/td><td>16-bit 5-100mA<\/td><td>Error flag<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9736","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=9736"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9736\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=9736"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=9736"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=9736"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=9736"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
