The 1\/4-unit load receiver impedance allows up to 128 nodes on a single bus. The fail-safe receiver design outputs logic-high when the bus is idle, open, or shorted, eliminating the need for external bias resistors in many applications.","working_principle":"The SN65HVD75DR provides bidirectional half-duplex communication between a UART (TXD\/RXD) and the RS-485 differential bus (A\/B). The driver converts single-ended TXD to differential A\/B signals, while the receiver converts differential A\/B to single-ended RXD. The DE (driver enable) and RE (receiver enable) pins control the direction. The 1\/4-unit load (48kOhm) receiver impedance allows 128 devices on one bus (vs. 32 for full unit load). The fail-safe receiver ensures logic-high output when the differential input is between -200mV and +200mV, covering idle and open-circuit bus conditions.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>R<\/td><td>Output<\/td><td>Receiver data output<\/td><\/tr><tr><td>2<\/td><td>RE<\/td><td>Input<\/td><td>Receiver enable (active-low)<\/td><\/tr><tr><td>3<\/td><td>DE<\/td><td>Input<\/td><td>Driver enable (active-high)<\/td><\/tr><tr><td>4<\/td><td>D<\/td><td>Input<\/td><td>Driver data input<\/td><\/tr><tr><td>5<\/td><td>GND<\/td><td>Ground<\/td><td>Ground<\/td><\/tr><tr><td>6<\/td><td>A<\/td><td>I\/O<\/td><td>Bus A (non-inverting)<\/td><\/tr><tr><td>7<\/td><td>B<\/td><td>I\/O<\/td><td>Bus B (inverting)<\/td><\/tr><tr><td>8<\/td><td>VCC<\/td><td>Power<\/td><td>3.3V supply<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Industrial Modbus RTU RS-485 bus at 25Mbps<\/li><li>Building automation BACnet MS\/TP bus<\/li><li>Motion controller servo drive communication<\/li><li>Security camera PTZ control RS-485 bus<\/li><li>Smart meter AMR data collection bus<\/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>SN65HVD72DR<\/td><td>SOIC-8<\/td><td>1Mbps, lower speed<\/td><\/tr><tr><td>TI<\/td><td>SN65HVD82DR<\/td><td>SOIC-8<\/td><td>5V, 1Mbps<\/td><\/tr><tr><td>Maxim\/ADI<\/td><td>MAX3485ECSA+<\/td><td>SOIC-8<\/td><td>3.3V, 10Mbps<\/td><\/tr><tr><td>Renesas<\/td><td>ISL83078EIBZ<\/td><td>SOIC-8<\/td><td>3.3V, 256 nodes<\/td><\/tr><tr><td>TI<\/td><td>THVD1500DR<\/td><td>SOIC-8<\/td><td>3.3-5V, 1Mbps, lower cost<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/9999","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=9999"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/9999\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=9999"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=9999"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=9999"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=9999"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
