The low 3pF capacitance ensures minimal signal degradation on high-speed data lines up to 1GHz.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>I\/O 1<\/td><td>Data line 1 (bidirectional)<\/td><\/tr><tr><td>2<\/td><td>GND<\/td><td>Ground reference<\/td><\/tr><tr><td>3<\/td><td>I\/O 2<\/td><td>Data line 2 (bidirectional)<\/td><\/tr><tr><td>4<\/td><td>I\/O 3<\/td><td>Data line 3 (bidirectional)<\/td><\/tr><tr><td>5<\/td><td>VCC<\/td><td>Power supply reference<\/td><\/tr><tr><td>6<\/td><td>I\/O 4<\/td><td>Data line 4 (bidirectional)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>USB 2.0 data and VBUS protection<\/li><li>Ethernet 10\/100\/1000 port ESD<\/li><li>DVI\/HDMI interface protection<\/li><li>Sim card ESD clamp<\/li><li>Firewire IEEE 1394 protection<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Spec1<\/th><th>Spec2<\/th><\/tr><tr><td>PRTR5V0U2X<\/td><td>Nexperia<\/td><td>2-line 1pF<\/td><td>SOT-363<\/td><\/tr><tr><td>TPD4E05U06DQAR<\/td><td>TI<\/td><td>4-line 0.5pF<\/td><td>USON-10<\/td><\/tr><tr><td>USBLC6-4SC6<\/td><td>STMicro<\/td><td>4-line 3pF<\/td><td>SOT-23-6<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/9738","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=9738"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/9738\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=9738"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=9738"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=9738"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=9738"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
