Product Description

Digital circuit training topic, understand the counter / frequency divider principle, familiar with the truth table

Multi-channel waveform generators are designed with integrated devices.

principle:

Using 74HC 4060 as clock source and frequency division.Device, produce 262.144 khz-256 hz square wave signal, 74HC 393 frequency divider output 128 hz-1 hz square wave signal. A total of 8 square wave signal, choose one of the 4 square wave (8hz; 4hz, 2hz, 1hz) output drive 4 NPN transistor, light up 4 LED. The 74HC 4060 consists of an oscillator section and a 14-way binary counter. The oscillator portion and the external RC oscillator or Crystal oscillator form the clock source.
