tl377 cn datasheet - ASAP -

Question: Who can help me with an obsolete IC made by Texas Instruments around 1990.
 
The model is:   TL377 CN
 
I know where to buy it an I have only one just now. This is not the problem.
I can buy another at the same place I did.
 
The problem: neither the seller nor anybody in ANY site in the Internet  can  find out the datasheet.
This is a MUST for me to fix problems related with DC speed motor controls
 
Please be so kind to FW this mail to the more appropriate technical support personnel in TI. or anywhere 
I will appreciate it too much
I believe it is a  PWM  IC  capsulated in 16 DIP, but with other non commercial TI name
 
Greetings
Eng. Rodolfo Rodriguez  
 
PS: conclusion.  I DO NEED THE TL377 CN  DATASHEET. manufactured by TI  ASAP.  That´s all
  • Hi, Rodolfo,

    I looked thru our systems, and could not find this part #, either. Sometimes we build custom ICs and/or marking for people and are contractually bound not to disclose this information. Since I can't find any info on this, I assume this is the case for your part.

    Sorry we couldn't be of more assistance. If the company that made this originally is still in business, you might contact them for schematics and additional information.

  • Hi Don

     

    Yes  the company that made this originally is still in business, but we have not any more commercial neither tech. support.

    As a matter of fact they don´t want to help us by no means at all !

    As I told you first, I can buy the TL377 CN. But:  1) How am I sure the IC is not a counterfeit with just the name stamped over it. 2) I still have not ANY datasheet.

    I send two very good quality pictures. One IC was the original one, the other who knows ?

    Thank you for your answ.
