IC 541 pinout

[newperson]

Hi,
I have an old IC that I cannot find the pinout on.  It has a house part number but also 541 printed on it.  The IC is 14 pin and is a power amp.  Was there a 541 14 pin amp IC in the late 1970s?  I have googled and cannot find any info to identify the IC.  The house number is 17-01-119185-02.

01-119185-02 cross-references to the LM380 power amp chip.
