本文介绍一种多功能的CMOS计数器CC4029(与CD4029产品对应)。它不仅具备予置数、加、减功能,而且还能用于二-十进制,也能用于二进制。故其用途极为广泛、灵活,尤其是在做各种线路试验时,可以根据每次试验的不同情况,把它变换成各种功能的计数器,有以一当十之功效。计数器的基本原理,许多书刊均有介绍。CC4029计数器的基本原理和一般计数器大同小异,故不再赘述。本文将简要叙述它的多种功能,然后分析它的各
This article describes a versatile CMOS counter CC4029 (corresponding to the CD4029 product). It not only has the preset number, plus, minus function, but also for two - decimal, can also be used for binary. Therefore, its use is extremely broad and flexible. Especially when doing various circuit tests, it can be transformed into counters of various functions according to the different conditions of each test. The basic principle of counter, many books have introduced. CC4029 counter and the general principle of the same counter, it will not repeat them. This article will briefly describe its many functions, and then analyze each of them
