... Contact the factory for further details. These devices are pin–for–pin replacements for Motorola’s first generation of MC14400/01/02/03/05 PCM mono–circuits and are upwardly compatible with the MC14404/06/07 codecs and other industry standard codecs. They also maintain compatibility with Motorola’ ...
