processing does notnecessarily include testing of all parameters.ABSOLUTE MAXIMUM RATINGSRECOMMENDED OPERATING CONDITIONSPCM1801SBAS131C–OCTOBER 2000–REVISED JULY 2007This integrated circuit can be damaged by ESD.Texas Instruments recommends that all integrated circuits be handled with appropriate precautions.Failure to observe proper handling and installation procedures can cause damage.ESD damage can range from subtle performance degradation to complete device failure.Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.PACKAGE/ORDERING INFORMATIONPRODUCTPACKAGE PACKAGE PACKAGE ORDERING TRANSPORT QUANTITYTYPE CODEMARKING NUMBER MEDIAPCM1801U Rails 56PCM1801U14-pin
