It supports data rates up to 20Mbps with \u00b115kV HBM ESD protection on bus pins. The guaranteed failsafe receiver output goes high when the bus inputs are open or shorted, preventing undefined data. The 1\/8 unit load allows up to 256 nodes on a single bus. The 5\u00b5A micropower shutdown mode is achieved by driving DE low and RE high, making it ideal for battery-powered applications. The driver outputs are glitch-free during power-up and power-down, preventing bus corruption in hot-plug systems. The MSOP-10 package (3 x 3mm) saves board space compared to SOIC packages.","working_principle":"The LTC2852IMS converts between 3.3V TTL\/CMOS logic levels and RS-485 differential bus signals in full-duplex mode. The driver section takes the DI input and, when DE is high, drives the Y and Z outputs as a differential pair: DI high produces positive VOD (Y>Z), DI low produces negative VOD (Y\n

LTC2852IMS uses the 10-lead MSOP (3x3mm) surface-mount package from Analog Devices: Pin 1 = RO (Receiver Output), Pin 2 = RE (Receiver Enable, active-low), Pin 3 = DE (Driver Enable, active-high), Pin 4 = DI (Driver Input), Pin 5 = GND, Pin 6 = Y (Driver Output, non-inverting), Pin 7 = Z (Driver Output, inverting), Pin 8 = B (Receiver Input, inverting), Pin 9 = A (Receiver Input, non-inverting), Pin 10 = VCC (3.0-3.6V). This is a full-duplex transceiver \u2014 driver and receiver operate simultaneously on separate bus pairs (Y\/Z for transmit, A\/B for receive). For half-duplex, short Y to A and Z to B. The MSOP-10 pinout is compatible with LTC2850\/2851\/2853 family devices.<\/p>","application_scenarios":"
