Abstract: -wire process instruments. 1.1 Features of the A5191HRT · Same modem design as LSI 20C15 · Transmits a , the LSI/NCR 20C15 for all existing and future HART applications. The A5191HRT is a near pin-for-pin replacement for the 20C15. The A5191HRT can be used in any circuit that uses the LSI 20C15 with no circuit , resistors is different than those used in the LSI 20C15. The four resistor values were changed because the A5191HRT is not exactly the same as the 20C15. They are both made using 0.5um CMOS processes and the AMI Semiconductor

Abstract: modem design as LSI 20C15 Transmits a trapezoidal signal Internal oscillator cell Internal receive , 24, 1999). The A5191HRT is intended to replace the LSI/NCR 20C15 for all existing and future HART applications. The A5191HRT is a near pin-for-pin replacement for the 20C15. The A5191HRT can be used in any circuit that uses the LSI 20C15 with no circuit topology changes. Only the values of four external , than those used in the LSI 20C15. The four resistor values were changed because the A5191HRT is not ON Semiconductor
