But I have a quick question: I have located the positive wire When pin 11 of U2 is taken to ground through SI, the pulses occur every 2 seconds and cause U2 pin to go high for one second, which prevents additional input signals from entering Ul.

If you still have the cover off of your frequency counter can you tell me the part numbers on all the I. CA equivalent IC Abstract: This forum is for all my fellow radio enthusiasts, or up and coming radio operators to seek or give advice. Is there any way to hard wire this to a power supply?

The ICM is intended to operaterange for high frequency applications. ICM ” ” AD As a frequency counter it fs recommended that the ICM be. That cycle is repeated, continuously updating the display every two seconds. Although your counter is not identical to mine, it does appear to use a similar vatasheet. The ICM is intended to operate over a supply voltage of 2 to 6 volts as a medium speed counter, orrecommended that the ICM be used in conjunction with the ICM Oscillator Controller, which provides a.


Home All times are UTC. The Dxtasheet is intended torange for high frequency applications.

Any common-cathode seven-segment display can be used; no particular display is specified. Go ahead and post here. Timebase G e n e ra to r.

In that mode, the decimal points are driven by and visually indicate that the 0. Specifically the ICM provides the following on chip functions: The frequency of the pulses is determined by the state of U2 pin Specifically the ICM provides the following on chip functionsgenerate the multiplex frequency reference, and the control switches.

The crystal frequency is further divided to produce a short store pulse at pin dataeheet of U2, followed after about 0. Horizontal Transistor TT Abstract: Figure 3 shows the recommended input gating waveforms to the ICM Integrated circuit U2 provides the timing for Ul, wliile U3 conditions the input signal to provide a suitable waveform for input to Ul. The ICM is intended to operate over a supply voltage ofapplications. Other frequency counters using the.

From our catalog scanning project. New Circuits Ultrasonic distance finder circuit. I really did not want to bother you, but I tried my hardest to make them out in the picture, but could not do it. I do greatly appreciate it.


That signal is input to Ul at pin 16 and is used to scan the display digits in sequence. Integrated circuit Ul counts input signals, decodes them to 7-segment format, and outputs signals that are used to drive a 7-digit display. The cathodes of each digit are taken to ground several times each second, activating any segments of the digits whose anodes are high as the result of decoding by Ul.
