HI-506L

      The HI-506L and HI-507L are single 16/differential 8channel CMOS analong multiplexers with latches and overvoltage protection.The HI-506L and HI-507L has 11 features.The first one is analong overvoltage protection.The second one is resettable latches(RS).The third one is TTL/DYL and CMOS compatible.The fourth one is no SCR latch-up.The fifth one is break-betore-make switching.The sixth one is microprocessor bus compatible.The seventh one is very low leakage - ID (off) 8nA (typ) over full temp rage.The eighth one is access time - tA = 500nS(typ).The ninth one is fallsafe for conditions of overvoltage & loss of power.The tenth one is minimum write pulse width (WR) = 300nS.The eleventh one is OFF isolation = -100dB,typ @ 10kHz.
      These HI-506L and HI-507L monolithic CMOS multiplexers feature on-board address latches,plus overvoltage protection for the analog input and the output as well.Each model includes digital input for channel selection and an enable input for device selection under program control.In addition,write(WR) and reset(RS) inputs allow the program to store or clear the channel address.The overvoltage performance of these multiplexers is particularly useful in redundant systems.Where the input and output must present a high impedance when power is off.This is schieved by a switch cell with three MOSFET's in seres,rather than the conventional transmission gate design.Each channel can withstand overvoltage to +-25VDC with respect to ground with power ON or OFF channl remains OFF in the presence of overvoltage.If the channle ia ON.Output voltage is clamped below the supply rail which protects the load circuit.
      The HI-506L and HI-507L offer 16 signle-ended channels,and the HI-507L is an 8 channel differential version.The recommended supply may also be implemented.The package is 28 pin ceramic or plastic DIP.Each product is specilied for the commercial temperature range (0 °C to +75 °C,-5 suffix) and the military range (-55 °C to +125 °C,-2 suffix).Military high reliability burned-in product is available as a -8 suffix.
