ARX2443

ARX2443 is new generation transceiver design which performs the front-end analog function of inputting and outputting data through a transfomer to the data bus.There are some features of ARX2443 as follows.First is low power dissipation.The second is smallest single transceiver ARX2443 available.Besides,dual transceiver saves cost and space.Then is outstanding MIL-STD-1553 electrical performance.Next is dual transceiver package options.The sixth is single 5 V supply operation.The last one is thick film hybrid technology.

What comes next is about the absolute maximum ratings of ARX2443.The V_CC (supply voltage) is from -0.3 to +7.0 V.The logic input voltage is from -0.3 to +5.5 V.The receiver input voltage (common mode) is ±5 V.The receiver differential input is ±10 V.The driver peak output current is 800 mA.The total power dissipation over full operating case temperature range is 1.6 W.The _JC (thermal resistance for the hottest device junction to case) is 96 /W.The maximum junction to case temperature rise for the hottest device is 20.The operating temperature is from -55 to +125.The storage temperature is from -55 to +150.

The following is about the electrial characteristics of ARX2443 for driver section.The maximum I_ILD ("0" input current) is -0.8 mA at V_IN=0.4 V.The maximum I_IHD ("1" input current) is 80 A at V_IN=2.7 V.The maximum V_ILD ("0" input voltage) is 0.7 V.The minimum V_IHD ("1" input voltage) is 2.0 V.Then is about the electrial characteristics for receiver section.The minimum Z_IN (differential input impedance) is 10 Kohms at f=1 MHz.The maximum V_IDR (differential voltage range) is ±4.0 Vpeak.The minimum V_ICR (input common mode voltage range) is ±2.5 Vpeak.The minimum CMRR (common mode rejection ratio) is 40 dB.
