I have a circuit using the NE555 wired in the typical astable operation. I am using ~6.1V input (Vdd). However my ouptput square wave is measuring 3.2V. I need the ouput square wave to be at least 5V.
What is causing this and what can I do to correct this problem?
FWIW I also tried using ~12V input but I kept burning up chips. It seems to work fine with the lower volate but I am getting the unwanted voltage drop.
See if this works. I did this quickly and please keep in mind that drawing electrical schematics are not part of my job so forgive me if I got a symbol wrong.
The switch is actually a double pole double throw switch but the second switch is practically independent with its own power supply. The output of the relay is also on that second schematic.
I'm not sure what information you may need on the counter/timer. If you have specific questions let me know and I can look it up for you. Thanks again.
The output of a NE555 (Fairchild Version) is rated at 100mA output at 5 volts, however at this output the voltage is down to 3.3 volts. Sounds like you have more than 100mA load on your output. The coil resistance of your relay need to be greater than ~100 ohms for a 5 volt relay.
I did't realize you were using a SS relay. Accordig to the data sheet, the input resistrance should be 1500 ohms, minimum. You're timer should be capable of driving that directly, unless I'm missing something.
Try disconnecting the relay and measuring the output of the timer. Maybe something else is going on.
