These devices are pinforpin replacements for Motorola's first generation of MC14400/01/02/03/05 PCM monocircuits and are upwardly compatible with the MC14404/06/07 codecs and other industry standard codecs. They also maintain compatibility with Motorola's family of MC33120 and MC3419 SLIC products. The ML1455xx family of PCM CodecFilter monocircuits utilizes CMOS due to its reliable lowpower performance and proven capability for complex analog/digital VLSI functions. ML145502
