DS26LS32AC: Equivalent Schematics of Differential Input

Fumio,

I'm looking into this. I will get back to you soon. Can you also advice what your customer cares, like the input impedance?

Regards,

Hao

Hi Hao-san,

Thank you for your quick reply.

The customer wants to get the equivalent schematics like AM26LS32A below.

Best regards,

Fumio,
You can use the same schematic by making some changes: 1) removing 100kOhm pull up / pull down resistors, 2) changing 20kOhm to 7.2kOhm, 3) changing 960Ohm to 900Ohm. Please let me know if you have more questions.

Hao-san,

Thank you for your answer.

Is the equivalent circuit diagram below correct?

Hao-san,

Thank you!!

Hao-san,

Thank you for your cooperation.

After I answered the question to the customer, the customer pointed out the description
in the datasheet. The datasheet describes below.

 "The DS26LS32A differs in function from the popular DS26LS32 and DS26LS33 in that input
  pull-up and pull-down resistors are included which prevent output oscillation on unused channels."

Which is correct? 
If the datasheet is correct, please let me know the values of pull-up and pull-down resistors

Fumio,

The datasheet is right. The schematic I found is actually from DS26LS32. Sorry for my ignorance here. I'll find the pull up / pull down information for you.

Hao-san,

Thank you for your reply.
I will wait for your imformation.
