Anyone know of some small (e.g., SOT-23, SC70, etc.) open collector output
driver that can sink, say, 100mA, can stand off, say, 32V, and is controlled
by a logic level (5V or 3.3V CMOS) input?
The ideal is to take the slightly wimpy outputs from a microcontroller and

Hi Group
I have four 22 way 2 side edge connector (0.156 inch pitch) into which
I mount cards used to control my model trains.  The edge connectors I
have are the ones with eyelets for cables to be soldered in.  These

Similar question to one I asked a while ago, but this time for UK, not
China:
I need to refer an English customer to a retail source for quantity ONE of a
wall-wart power adapter, so he can use a product I make.  (I make it in the

Has anyone encountered an analysis of the values of electronic
components such as inductors, capacitors, etc at fractional light speed,
where, presumably, mass and size change with velocity?

Im confused regarding the choice of iron powder toroid for a 7Mhz high pass
filter. I need to use a small size (T68) toroid. For the freq range, some
reference texts say T68-2 is the one, others say T68-6" grade. I see
differing "best Q range" specs for the 6

Looking for a UK source of this part or indeed of any New Japan Radio parts.

I am putting together an underwater housing for a video camera. I can't
use the built in viewfinder or the built in lcd do to the design
constraints of the housing. I want to use an LCD module that I pulled
out of a defective digital camera.

I need a divide by N chip, covering a divide range of 20 to 300 or so.
I know I can build it with a binary counter and an 8 input nand gate.
But, I'd like to have it all in one chip if possible.
They used to make these things for phase locked loop building blocks,

Perhaps do someone know what is a chip labeled AMI 8436, and another one
labeled AMI 8438?
I got a couple of them but I don't know what they are.
Thank you very much.

Does anyone know of any NTE2320-equivalent ICs?
The NTE2320 has 2 NPN and 2 PNP transistors, in a 14-pin DIP package
(two matched pairs).

i am searching for an Diff-OPAmp.
I´ve got two signals between 0 and 1 V, Audio frequencies.
A possible supply voltage of 0-5 V and very few available space.
Does anyone have some suggestions what component would be good to use?

HI.  Does anyone know where i can obtain a couple of  these ic,s  by mail
order. As component dealers here in the UK do not stock them.  Any info
would be appreciated.

For a Micro scale radio transceiver for a sensor network demonstration,
roI'm looking for a very small and light weight radio tranceivers capable of
transmitting and receiving digital data within 3 meters radius.
Followings are desired specifications;

I have a detector with pairs of output lines: Q and Q NOT.
I am told that I need to look for a 5V difference between Q and Q NOT
in order to record an event; just watching for Q going high is not
good enough, Q NOT has to go low at the same time.  This is in order

I have a 4 by 1 inches electronic programmable led signs with a up to
