SEMICONDUCTOR TECHNICAL DATA  
The MC145500, MC145501, MC145502, MC145503, and MC145505 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 MC145500 and MC145503 are general  
purpose devices that are offered in a 16–pin package. They are designed to  
operate in both synchronous and asynchronous applications and contain an  
on–chip precision reference voltage. The MC145501 is offered in an 18–pin  
package and adds the capability of selecting from three peak overload voltages  
(2.5, 3.15, and 3.78 V). The MC145505 is a synchronous device offered in a  
16–pin DIP and wide body SOIC package intended for instrument use. The  
MC145502 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  
and contains all the features of the MC145500 and MC145501 plus several  
more. Most of these features can be made available in a lower pin count  
package tailored to a specific user’s application. 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’s family of MC33120 and MC3419 SLIC  
products.  
The MC145500 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.
