Can anyone give me anything on this? I thought I actually had a
datasheet, but  (NOT!)freetradezone had mixed it for the upc2722C. I
found a UPC272C in a very humble little driver board, and was thrown
nicely for a few minutes :-/. FYI, the uPC is a 'Silicon MMIC Frequency
Converter' boasting they are 'L-Band Frequency converters (2.8 ghz)
using the Nesat III process", and with converters, VCOs, and other
technological gobbledygook being thrown around like snuff at a wake.


I think it's a quad opamp like the lm324, but I'd like to be sure.
Mebbe actually the LM224 - industrial temprature. None of the other crap
anyhow .
uPC272C?
Is this a 14 pin DIP?

If so, it can be found in the famous japanese databook collection...

There it is described as a dual comparator:
3 A GND
4 A+ in
5 A- in
6 V-
7 B out
8 B GND
9 B +in
10 B -in
11 V+
12 A out
other pins NC.
Output is open collector (needs pull up).
