AM26C31: About data sheet

Part Number: AM26C31

Hi support team,

We have received questions from our customer.

In the data sheet Rev. O, there are notes that is described "See Figure 2" and "S1 Open" in the graph of Figure 1.
But there is no "S1" in Figure 2.
What is the correct test circuit? Is it as shown in Figure 3?

And in Figure 2 the load is described as RL / 2.
I think the concrete value of RL is 100 Ω.
Is is correct?

Best regards,
M. Tachibana

  • Hello Masanori,

    You are correct, they are supposed to reference Figure 3. I am going to get the data sheet revised so there errors are eliminated. As for the RL resistance, the load is correct. The Characteristics table on page 6 references VOD where the resistance it sees is 100 Ohms, that is why there are two 50 Ohms in series at the end. The figure and table don't match exactly with the naming, but it is correct.

  • Hello Matt-san,

    Thanks for your reply.
    I understood what you taught, and I will contact our customer soon.

    Best regards,
