U 6050B

      The U 6050B is widely used for permanent scanning of 8 switch-positions,serial data transmission via s single data line and driving up to 8 relays.Here are the features as follows.The first one is thar only a sigle line is necessary.The quadriple comparison of the data signal for high transmission safety.All outputs switched off if data line is disturbed.Besides,U 6050B has the function of short circuit detection of the intergrated relay driver.The transmitter and receiver is prepared for master/slave operation (16 switches,16 relays).It has reduced power dissipation by pulse driver outputs and the transmitter data output short circuit is protected.The transmitter can be powered via data line.What's more,it has wide supply voltage range.Furthermore,it has 8 relay drivers.U 6050B meets the demands of VDE regulation 0839 and has the function of load dump protected.
      What comes next is about the U 6050B absolute maximum ratings.The supply voltage (static:no operation 60 s) (V_S) is 25 V.The ambient temperature range (T_amb) is from -40 to +85 .The storage temperature range (T_stg) is from -55 to +125 .The junction temperature (T_j) is 150.The power dissipation (P_tot) is 810 mW at T_amb=85.Then is about the maximum thermal resistance.The junction ambient (R_thJA⁾ is 80 K/W at DIP 18 and 100 K/W at SO 20.The following is about the electrical characteristics (V_Batt=13.5 V,T_amb=25,reference:GND).The minimum supply voltage (V_Batt) is 6 V and the maximum is 16 V.The typical stabilized voltage (V_stab) is 5.2 V.The minimum protection resistor (R_V) is 510.The typical filter capaitor (C_V) is 100 F.The typical current consumption (I_S) is 1.5 mA.The typical internal clamping (V_Z) is 14.3 V.
