What is TI 27M4BC?

[csharp]

Hello,

I'm hoping that someone can tell
me what the following part is.

The markings on this 14 pin
SOIC are as follows;

TI731BN
27M4BC

I've called TI and they say it's
not one of their part numbers.

However I've found these parts for
sale by a couple of brokers as
TI parts.

It's not an opamp, I checked one
to see if it was a TLC series part.


Best regards,
csharp

Are you sure?

TLC27M4 is listed on the TI website as a quad precision op amp, although the package code should be BCD for a commercial grade 2mV offset in a small outline package:

Hello,

I'm sure it's not an opamp. I hooked
one up as a buffer and did an AC test,
no joy.
