The slew-rate limited driver outputs minimize electromagnetic interference (EMI) and reduce reflections caused by improperly terminated cables, enabling error-free data transmission at up to 250 kbps. The device features separate driver enable (DE) and receiver enable (RE) controls for flexible bus management. A shutdown mode reduces supply current to just 2 nA, making it ideal for battery-powered applications. The receiver includes a fail-safe feature that outputs a logic high when inputs are unconnected.","working_principle":"The ADM3483ARZ converts between single-ended TTL\/CMOS logic levels and differential RS-485\/RS-422 bus signals. The driver takes a single-ended input (DI) and generates complementary differential outputs (A and B) with slew-rate limiting to control signal edge rates. The receiver converts the differential bus voltage (A-B) back to a single-ended output (RO). In half-duplex mode, the driver and receiver share the same bus pins (A and B), with DE and RE controls determining whether the device is transmitting or receiving. The slew-rate limiting circuit slows output transitions to reduce high-frequency spectral content, minimizing EMI and allowing reliable operation with improperly terminated cables. The thermal shutdown circuit disables the driver if the junction temperature exceeds approximately 150\u00b0C.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>RO<\/td><td>Receiver Output<\/td><\/tr><tr><td>2<\/td><td>RE<\/td><td>Receiver Output Enable (active low)<\/td><\/tr><tr><td>3<\/td><td>DE<\/td><td>Driver Output Enable (active high)<\/td><\/tr><tr><td>4<\/td><td>DI<\/td><td>Driver Data Input<\/td><\/tr><tr><td>5<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>6<\/td><td>A<\/td><td>Non-inverting Bus I\/O<\/td><\/tr><tr><td>7<\/td><td>B<\/td><td>Inverting Bus I\/O<\/td><\/tr><tr><td>8<\/td><td>VCC<\/td><td>3.3V Power Supply<\/td><\/tr><\/table>","application_scenarios":"The ADM3483ARZ is widely used in industrial process control networks where multiple devices communicate over long RS-485 buses. The slew-rate limiting makes it particularly suitable for applications with cable lengths up to 4000 feet at lower data rates. In HVAC systems, it enables communication between thermostats, controllers, and actuators. The 2 nA shutdown current is critical for battery-powered remote sensors that wake periodically to transmit data. The 3.3V supply compatibility allows direct interface with modern low-voltage microcontrollers without level shifting.","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Difference<\/th><\/tr><tr><td>ADM3485ARZ<\/td><td>Analog Devices<\/td><td>10 Mbps data rate version<\/td><\/tr><tr><td>ADM3483EARZ<\/td><td>Analog Devices<\/td><td>\u00b115kV ESD protected version<\/td><\/tr><tr><td>SP3485CN<\/td><td>MaxLinear<\/td><td>3.3V, 10Mbps alternative<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/6482","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=6482"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/6482\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=6482"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=6482"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=6482"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=6482"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
