hi Gayan,
I often use these in conjunction with TTL/PIC's, CMOS, OPA's etc with a 5V supply. no problems.
It really depends upon what the 2N7000 is being used for, eg Ids range.?
Its a mini 5X7 LED matrix project.I'm using a PIC.
Most important thing is this must power from batteries.
This is a hand held project so it must use batteries.To make the design compact I planned to use MOSFETS instead of BJTs.So I can eliminate base resisters as well.

Well I have to admit that I neglected to check what price I was up against... I was more up at arms over the package really.
It is not easy to solder that pitch by hand when there are leads, never mind when there aren't. I am assuming he is trying to solder leads to it, as most here would not have PCBs for that kind of work.

hi,
I bought some ADS1100 16 bit adc's recently, they are small!, I have a bench magnifier and they are still small.
The solder iron tip looks like a jack hammer.
The idea is to mount one piggy back on a 16F876, using Kynar to wire the legs to the SPI lines of the PIC, pick up the PIC power and 'share' an analog input.
Its going to be a rainy day job..

I always use minimum and maximum spec's instead of a "typical" graph.
The graph for a "typical" 2N7000 Mosfet shows lots of output current when its input voltage is low. But the specs have a maximum theshold voltage of 3.0V when the current is only 1mA. It is spec'd to conduct well when its gate is 4.5V and 10V.
You don't know if you get a good one or or not so good one when buying a 2N7000 Mosfet.
