It features one driver and one receiver, supporting up to 256 nodes per bus via one-eighth unit load receiver input impedance. Guaranteed failsafe receiver operation over the entire common-mode range ensures a logic-high output under open or shorted bus conditions. Enhanced ESD protection withstands plus or minus 15 kV HBM on transceiver pins without latchup. Current-limited drivers and thermal shutdown protect against bus contention, while micropower shutdown mode reduces supply current to 5 uA maximum.","working_principle":"The LTC2852IMS implements a full-duplex RS485\/RS422 transceiver with independent driver and receiver signal paths operating simultaneously. The driver converts single-ended TTL\/CMOS logic levels (applied to the DI pin) into differential RS485\/RS422 output signals on the Y and Z pins. The driver output stage uses a current-limited H-bridge topology that drives the differential output voltage to a minimum of 1.5 V across a 54 Ohm load (two 120 Ohm termination resistors in parallel). The receiver monitors the differential voltage between the A and B pins and converts it to a single-ended logic level at the RO output. A 150 mV receiver hysteresis provides noise immunity on slowly transitioning bus signals. The receiver failsafe biasing ensures the RO output is high when the bus is idle (open or terminated but undriven). Driver and receiver enable pins (DE and RE) allow independent control. The micropower shutdown mode is entered when both DE is low and RE is high, reducing quiescent current to 5 uA. The thermal shutdown circuit disables the driver when the die temperature exceeds approximately 150 C, automatically re-enabling when the temperature drops.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>RO<\/td><td>Receiver output; logic level corresponding to differential input A-B<\/td><\/tr><tr><td>2<\/td><td>RE<\/td><td>Receiver enable; active low, high impedance output when high<\/td><\/tr><tr><td>3<\/td><td>DE<\/td><td>Driver enable; active high, high impedance outputs when low<\/td><\/tr><tr><td>4<\/td><td>DI<\/td><td>Driver input; TTL\/CMOS compatible data input<\/td><\/tr><tr><td>5<\/td><td>GND<\/td><td>Ground reference<\/td><\/tr><tr><td>6<\/td><td>Y<\/td><td>Driver non-inverting output; RS485\/RS422 bus line<\/td><\/tr><tr><td>7<\/td><td>Z<\/td><td>Driver inverting output; RS485\/RS422 bus line<\/td><\/tr><tr><td>8<\/td><td>B<\/td><td>Receiver inverting input; connects to RS485\/RS422 bus<\/td><\/tr><tr><td>9<\/td><td>A<\/td><td>Receiver non-inverting input; connects to RS485\/RS422 bus<\/td><\/tr><tr><td>10<\/td><td>VCC<\/td><td>3.3 V power supply (3.0 V to 3.6 V)<\/td><\/tr><\/table>","application_scenarios":"<ul><li><strong>Industrial RS485 Networks<\/strong>: Multi-node communication in factory automation with 256-node bus capability<\/li><li><strong>Backplane Transceivers<\/strong>: High-speed 20 Mbps differential signaling across card cage backplanes<\/li><li><strong>Level Translation<\/strong>: Converting between single-ended logic and differential RS422 signaling for cable drivers<\/li><li><strong>Building Automation<\/strong>: BACnet MS\/TP and Modbus RTU communication over RS485 cabling<\/li><li><strong>Motor Drive Communication<\/strong>: Command and telemetry links between servo drives and host controllers<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Rate<\/th><th>Supply<\/th><th>Duplex<\/th><th>Package<\/th><\/tr><tr><td>LTC2851IMS<\/td><td>Analog Devices<\/td><td>20 Mbps<\/td><td>3.3 V<\/td><td>Half<\/td><td>MSOP-8<\/td><\/tr><tr><td>SN65HVD74<\/td><td>Texas Instruments<\/td><td>20 Mbps<\/td><td>3.3 V<\/td><td>Full<\/td><td>SOIC-14<\/td><\/tr><tr><td>ADM3485EARZ<\/td><td>Analog Devices<\/td><td>12 Mbps<\/td><td>3.3 V<\/td><td>Half<\/td><td>SOIC-8<\/td><\/tr><tr><td>THVD1550DR<\/td><td>Texas Instruments<\/td><td>50 Mbps<\/td><td>3.3 V<\/td><td>Half<\/td><td>SOIC-8<\/td><\/tr><tr><td>ISL3179EIHZ<\/td><td>Renesas<\/td><td>40 Mbps<\/td><td>3.3 V<\/td><td>Full<\/td><td>QSOP-16<\/td><\/tr><\/table>\n<p>LTC2852IMS is a 3.3V 20Mbps RS485\/RS422 full-duplex transceiver from ADI in MSOP-10 with \u00b115kV ESD.
