For example, if two are connected in a manner that input of one becomes the output of other, the second IC will receive a pulse on every tenth count and will reset at every hundredth count. Powering up 3 digit object counter with USB cable. How to make one transistor FM transmitter on a stripboard- page Virgin Galactic — Commercial Space Flight. The other high counts can be generated by connecting two or more ICs. Review of PCBWay after-sale service.
Output 3, BCD Output bit 2. It can be used as a divide by 10 counter by connecting Q A with clock input2, grounding all the reset pins, and giving pulse at clock input1.
