China, on December 6, 2018–The 3.3V RS485 of meaning law semiconductor is sent and receive implement what STR485LV offerred 20Mbps of an optional choose or 250kbps communication rate is exterior cite a base, can connect the low-pressure and logistic parts of an apparatus of lowermost 1.8V continuously, rose to design flexibility thereby.
Optional data rate leads the user the foot makes design personnel OK the function according to cable, will same send and receive implement use at join high speed / stone’s throw or most Sunday run (4000 feet) RS485 network, simplify the inventory management of RS485 parts of an apparatus. New product applies to all sorts of application setting, include link of data of telegraphic infrastructure, high speed or communication of low-pressure small controller.
New product offers agile join alternative to design staff, the data that uses 1.65V-3.6V and make can signal power source, need not the low-pressure and logistic parts of an apparatus that exterior n changes component to be able to connect 1.8V-3.3V continuously.
Does resistor of output of chip interior drive maintain in 96? Above, top job temperature raises 105°C, according to standard of technology of RS485 communication interface, STR485 can be on same bus line join is sent and receive 256 times at most implement.
New product holds an outstanding electric safety and dovish character concurrently, include heat to close to protect mode with receiver breakdown, former can bring about power comsumption in order to prevent bus line contention or breakdown too big, and latter is inputting disengaged, short circuit or mistake happening did not prevent when join. Bus line brings a foot to be able to bear the osculatory discharge that exceeds ±8kV and ±16kV air discharge, and without latch phenomenon, standard of prep above IEC 61000-4-2 sets, and can be able to bear or endure suffer IEC61000-4-4 standard B kind fast twinkling changes pulse.
STR485 already appeared on the market now, to simplify circuit board is designed, use 3mm X 3mm to shed general formula logic – bus line brings crural DFN10 to enclose.
