A distinguishing feature is its built-in 26-ohm series output resistors, which provide impedance matching for transmission line driving without requiring external termination components. The device is organized as two 4-bit buffer sections, each with an active-low output-enable input. Inputs can accept voltages up to 5.5 V, allowing use as a translator in mixed 3.3-V and 5-V environments. The Ioff circuitry supports live insertion and partial-power-down applications.","working_principle":"The SN74LVC2244APWR operates as two independent 4-bit buffer sections with active-low output-enable (1OE, 2OE) controls. When the OE input is low, the corresponding buffer section passes data from input to output with true polarity through integrated 26-ohm series resistors. These series resistors provide source termination for transmission lines, reducing reflections and improving signal integrity. When OE is high, the outputs assume a high-impedance state, enabling bus sharing. The Ioff circuitry ensures outputs are disabled when VCC is zero, preventing backflow current.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>1OE<\/td><td>Input<\/td><td>Output enable 1 (active low)<\/td><\/tr><tr><td>2<\/td><td>1A1<\/td><td>Input<\/td><td>Data input 1A1<\/td><\/tr><tr><td>3<\/td><td>2A4<\/td><td>Input<\/td><td>Data input 2A4<\/td><\/tr><tr><td>4<\/td><td>1A2<\/td><td>Input<\/td><td>Data input 1A2<\/td><\/tr><tr><td>5<\/td><td>2A3<\/td><td>Input<\/td><td>Data input 2A3<\/td><\/tr><tr><td>6<\/td><td>GND<\/td><td>Power<\/td><td>Ground<\/td><\/tr><tr><td>7<\/td><td>1A3<\/td><td>Input<\/td><td>Data input 1A3<\/td><\/tr><tr><td>8<\/td><td>2A2<\/td><td>Input<\/td><td>Data input 2A2<\/td><\/tr><tr><td>9<\/td><td>1A4<\/td><td>Input<\/td><td>Data input 1A4<\/td><\/tr><tr><td>10<\/td><td>2A1<\/td><td>Input<\/td><td>Data input 2A1<\/td><\/tr><tr><td>11<\/td><td>2Y1<\/td><td>Output<\/td><td>Data output 2Y1<\/td><\/tr><tr><td>12<\/td><td>1Y4<\/td><td>Output<\/td><td>Data output 1Y4<\/td><\/tr><tr><td>13<\/td><td>2Y2<\/td><td>Output<\/td><td>Data output 2Y2<\/td><\/tr><tr><td>14<\/td><td>1Y3<\/td><td>Output<\/td><td>Data output 1Y3<\/td><\/tr><tr><td>15<\/td><td>2Y3<\/td><td>Output<\/td><td>Data output 2Y3<\/td><\/tr><tr><td>16<\/td><td>1Y2<\/td><td>Output<\/td><td>Data output 1Y2<\/td><\/tr><tr><td>17<\/td><td>2Y4<\/td><td>Output<\/td><td>Data output 2Y4<\/td><\/tr><tr><td>18<\/td><td>1Y1<\/td><td>Output<\/td><td>Data output 1Y1<\/td><\/tr><tr><td>19<\/td><td>2OE<\/td><td>Input<\/td><td>Output enable 2 (active low)<\/td><\/tr><tr><td>20<\/td><td>VCC<\/td><td>Power<\/td><td>Supply voltage<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Wearable health and fitness devices<\/li><li>Network switches and router signal distribution<\/li><li>Server backplane bus drivers<\/li><li>Test and measurement equipment signal buffering<\/li><li>Transmission line drivers with integrated termination<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>TI<\/td><td>SN74LVC244APWR<\/td><td>TSSOP-20<\/td><td>Without series resistors<\/td><\/tr><tr><td>Nexperia<\/td><td>74LVC2244APW<\/td><td>TSSOP-20<\/td><td>Pin-compatible equivalent<\/td><\/tr><tr><td>TI<\/td><td>SN74LVCH2244APWR<\/td><td>TSSOP-20<\/td><td>With bus-hold inputs<\/td><\/tr><tr><td>Nexperia<\/td><td>74LVCH2244APW<\/td><td>TSSOP-20<\/td><td>Bus-hold variant<\/td><\/tr><tr><td>TI<\/td><td>SN74LVC2244AVDR<\/td><td>TVSOP-20<\/td><td>Thinner package option<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/10726","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/comments?post=10726"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/10726\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/media?parent=10726"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/categories?post=10726"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/tags?post=10726"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/chip_brand?post=10726"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
