Who is the actual manufacturer of this part

[FreshmanNewbie]

I see this part - LMC7101 has TI datasheet and also Microchip datasheet.

Who's the current manufacturer of this part? And any reason/history on this?

It's an original National Semiconductor part. NS was acquired by TI in 2011. Microchip is apparently supplying the part as second source.

 

[D.A.(Tony)Stewart]

When a design has expired it's patent it may be second sourced by any Mfg without royalty payments, They may copy the design or pay a fee for the source code of the layout.

Such is the case for this generic CMOS Op Amp.

There are now many sources.
