    driver circuit for a n-channel MOSFET

    Hi again jc_lim3 If you switch out your 74HC365 to a SN74LS07 it will work, at the same time remove the PNP transistor and the 2.2K and 10K resistors. connect the 4.7K resistor between 12V and the output of SN74LS07, also connect this to the mosfet gate. Maybee you should have a pair of...

    driver circuit for a n-channel MOSFET

    Hi jc_lim3 You haven't suplied us with enough information! ??? The smitt-trigger, what is that, is it feeded from an input of a microcontroller? ??? What is the output from the smitt-trigger? Open collector? Also, the gate cap of the mosfet makes it switch slow. //Staigen

    4PDT to SPDT trick

    Hi again Maybee there is an another solution after all, i didn't thought of it at first! The smitt-trigger- action resistors, do they need to be that big? Is it possible to rise them to, lets say, 100K or so? Than the current throu the switches are reduced, and also the voltage. Also an another...

    4PDT to SPDT trick

    Hi The other method is called BFS and stands for Brute Force Solution, in other words, use a relay! At least for the malfunktion switches. A DPDT relay, together with the MAX333, or a 4PDT relay without the MAX333! Sorry

    4PDT to SPDT trick

    Hi again MrHeckles I belive i found one more error, the bases of your LED driving transistors is not protected, a reversed diode(1N4148 or similar) will help that! //Staigen

    Hi MrHeckles I think i find one error, the pin number 5 of max333 shall be connected to a negative voltage, i

    VHF AMPLIFIER (PLZ ANSWER)

    Hi Isn't that one similar to one of the amps here on this site? You cant use a simple telescope antenna for DX-ing! The circuit seems to be a working circuit, but aso check the cirquit, that is similar, here at E-Lab. And use a good antenna, else you won't be hearing anything! //Staigen

    4PDT to SPDT trick

    Hi I didn't get that! Are "limit" an input or outpt to the machine? Are "forward limit" an input or output to the macine? Are "reverse limit" an input or output to the macine? Maybee they should be ored or anded together? //Staigen

    Hi I suppose so, dont it do that for you? If so, the IC is surely damaged! //Staigen

    Why Sink current is higher than Source current?

    Hi Audioguru Hehe, not that old, theres a digital family called RTL, hehehe

    Why Sink current is higher than Source current?

    Hi both of you How was it with the old RTL digital ICs, didn't they source more than sink? Or was it an another family, that have PNPs output, only similar to RTL? //Staigen

    VHF AMPLIFIER (PLZ ANSWER)

    Hi A TV antenna is not tuned to the FM band, and is not very good for DX-ing at FM! Was the other two amplifiers not good enough for amplifying the signal? It opened nice here, its an article from an australian mag, with an antenna amp. Do you have Acrobat Reader installed? //Staigen
