Advance Information

The MC145506, MC145507, and MC145508 are per channel codec–filter

PCM mono–circuits. These devices perform the voice digitization and

reconstruction, as well as the band limiting and smoothing required for PCM

systems. These devices have HCMOS compatible digital outputs and otherwise

supplement the MC145500 – MC145505 series of PCM codec–filters. The

MC145506, MC145507, and MC145508 are functionally similar to the

MC145502, MC145503, and MC145505, respectively. They are designed to

operate in both synchronous and asynchronous applications and contain an

on–chip precision reference voltage. The MC145506 is offered in a 22–pin

package and has the capability of selecting from three peak overload voltages

(2.5 V, 3.15 V, and 3.78 V). The MC145507 and MC145508 offer versatility and

low cost in 16–pin DIP and wide body SOIC packages. Most of the features of

these devices 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 maintain compatibility with Motorola’s family of MC3419/

MC33120 SLIC products.

The MC145500 family of PCM codec–filter mono–circuits utilize CMOS due

to its reliable low–power performance and proven capability for complex

analog/digital VLSI functions.
