When the output-enable (OE) input is high, the output is disabled (high-impedance). When OE is low, true data passes from the A input to the Y output. The device operates from 2V to 5.5V with a maximum propagation delay of 6 ns at 5V, making it suitable for high-speed signal buffering and bus isolation in mixed-voltage systems.","working_principle":"The SN74AHC1G125 consists of two main functional blocks: (1) 3-State Output Control: The OE (output enable) pin controls the output buffer state. When OE is HIGH, the output stage is placed in a high-impedance state, effectively disconnecting the device from the bus. When OE is LOW, the output is actively driven. (2) Non-Inverting Buffer: The input signal at pin A passes through a CMOS buffer stage to the Y output without inversion. The AHC (Advanced High-Speed CMOS) technology provides fast switching (6ns tpd at 5V) while maintaining low static power consumption (10\u00b5A max ICC).","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>OE<\/td><td>Input<\/td><td>Output enable (active-high disables output)<\/td><\/tr><tr><td>2<\/td><td>A<\/td><td>Input<\/td><td>Data input<\/td><\/tr><tr><td>3<\/td><td>GND<\/td><td>Ground<\/td><td>Ground<\/td><\/tr><tr><td>4<\/td><td>Y<\/td><td>Output<\/td><td>Data output (3-state)<\/td><\/tr><tr><td>5<\/td><td>VCC<\/td><td>Power<\/td><td>Supply voltage (2V to 5.5V)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Bus buffering and signal isolation in multi-master systems<\/li><li>3.3V to 5V level translation in mixed-voltage designs<\/li><li>Memory I\/O port enable\/disable control<\/li><li>Motor control signal conditioning with 3-state capability<\/li><li>Patient monitoring system signal routing<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Family<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>SN74AHCT1G125DBVR<\/td><td>TI<\/td><td>AHCT<\/td><td>SOT-23-5<\/td><td>TTL-compatible inputs<\/td><\/tr><tr><td>74LVC1G125GW<\/td><td>Nexperia<\/td><td>LVC<\/td><td>SOT-353<\/td><td>Smaller package option<\/td><\/tr><tr><td>MC74VHC1G125DTT1G<\/td><td>onsemi<\/td><td>VHC<\/td><td>SOT-23-5<\/td><td>Equivalent function<\/td><\/tr><tr><td>NC7SZ125P5X<\/td><td>Renesas<\/td><td>tinyUHC<\/td><td>SOT-23-5<\/td><td>Ultra-high speed<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/3402","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=3402"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/3402\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=3402"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=3402"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=3402"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=3402"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
