Hi guys,

I must be missing something, but I really struggle to identify a lot of=20
later smd ICs with weird codes.

The latest board I'm working on has a dozen mostly 8 and 14 pin SOIC's. Mos=
t=20
I've eventually been able to identify, but there are still two 8 pin ones I=
=20
need help with. I've tried as many combinations as I can think of in=20
searching, but still no joy.

They both have a label with three lines

2272A1    (or 2272AI)
24T
D6XE

The second,

2702C
46M
C9V7

Both of these chips appear to be linear devices, not digital, and running=20
with a VCC of 5 volts. I haven't been able to identify a company logo  ...=
=20
it has been hard enough reading what's on them as it is.

Thanks for any help with either these chips or perhaps a publication with=20
codes that identify various devices. I do have a manual for some of the mor=
e=20
common smd transistors and fets etc which is very handy.

Once I find what the IC is, the data sheet tells me the code on the package=
,=20
but that's the wrong way around. I need the code so I know what data sheet=
=20
to download.

How do you guys get on?

Regards,  Roger=20
