All types except FZLG. Wire as I suggested earlier and it should work fine. Equating complex number interms of the other 6.

Try changing the 4. GND is at pin 8 and Vcc at pin The results are not as expected. Instead, measure the datasheft at the input pins, it should be 5V if the switch is closed and almost 0V when the switch is open.

Digital multimeter appears to have measured voltages lower than expected. Thank you all for your help! Jan 20, 6.


AF modulator in Transmitter what is the A? What is the function of TR1 in this circuit 2.

It’s better to share your questions and answers on Edaboard so we can all benefit from each others experiences. If they are not actively pulled to logic low state, they internally assume the input is high. Try wiring the inputs like this: The overall datasbeet seems to be different and they drift to a “high” output.

The ICs are assuming their inputs are ‘1’ all the time and operating the switch is just providing a few microamps more to reinforce the ‘1’ state.

Some functions may be missing or not functioning. Arduino Pro Mini A link to the Motorola data sheet for the 74LS83A is below: Yes, dtaasheet password is: How can the power consumption for computing be reduced for energy harvesting?

All this means that there is a minimum of learning time required. Our office is open: However, a multimeter continuity test verifies a good connection for each of the 16 IC pins to the breadboard.


Many kinds of resistance value are lined up in order to support various 74s83 of circuit design.

I attached a picture of the setup and dattasheet a link to the Motorola 74LS83A data sheet. TI has documents on how to use each family, look it up. Be datashet though, if an input is not connected, it may appear to have low voltage on it when measured but still be ‘seen’ from insde the IC as being high, you actually have to draw current from the pin to be sure it really is logic low. Also reduce the value of the resistors in series with the LEDs to 1K so they can pass more current.
