Overview
The CD4059AM is a CMOS Programmable Divide-by-N Counter produced by Texas Instruments. This device is part of the CD4059A series and is available in a 24-pin SOIC (DW) package. It is designed for synchronous programmable N counting, with the capability to divide an input frequency by any number N from 3 to 15,999. The counter features fully static operation, mode-select control for initial decade counting, and TTL drive capability. It is particularly useful in communication digital frequency synthesis and various industrial control applications.
