www.DataSheet4U.com ML145502 ML145503 ML145505 PCM Codec–Filter Mono–Circuit Legacy Device: Motorola MC145502, MC145503, MC145505 The ML145502, ML145503, and ML145505 are all per channel PCM Codec–Filter mono–circuits. These devices perform the voice digitization and reconstruction as well as the band limiting and smoothing required for PCM systems. The ML145503 is a general purpose device that is offered in a 16–pin package. These are designed to operate in both synchronous and asynchronous applications and contain an on–chip precision reference voltage. The ML145505 is a synchronous device offered in a 16–pin DIP and wide body SOIC package intended for instrument use. The ML145502 is the full–featured device which presents all of the options of the chip. This device is packaged in a 22–pin DIP and a 28–pin chip carrier package 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’s family of MC33120 and MC3419 SLIC products. The ML1455xx family of PCM Codec–Filter mono–circuits utilizes CMOS due to its reliable low–power performance and proven capability for complex analog/digital VLSI functions.
