RE: Temic TSOP 1838

I did indeed :-(

I also contacted several wholesale suppliers who do stock the TSOP range
but
none of them had any stock and delivery was shown as Jan 2001.

Either the factories are making something more profitable or some major
manufacturer has bought the entire output of the factory for the next few
months.

The search continues.....
