AM26LS31 Quadruple Differential Line Driver datasheet (Rev. M)
1) As for 5.8 Typical Characteristics, as the following Figure5-1 and Figure 5-3; both the description of the figure are Output voltage vs Enable G Input Voltage;
but in fact, Vertical axis show the Y output voltage and Output voltage;
I want to know the difference between between Vertical axis show the Y output voltage and Output voltage;(as theFigure5-1 and Figure 5-3 show, the Vertical axis voltage is different)
2) As the Figure5-5, the Vertical axis is High-Level Output Voltage, I want to know the Output Voltage of High-Level Output Voltage is which one of the question 1)?
That means the High-Level Output Voltage is High-Level Output Voltage or High-Level Y Output Voltage
3)Figure 5-9 description is Y output voltage vs Data Input Voltage; Figure 5-14 description is Y output voltage vs Enable G Input Voltage;
Could you please tell me what is Date Input Voltage and what is Enable G Input Voltage;
Hello ,
1) it is different in load condition and A input change to show the output feature.
2) VCC=5V in Figure 5-1.
3) we sugget you design regarding the parameter below
1) I want to know the difference of Load=470Ω to GND in Figure5-1 and Load=470Ω to VCC, could you please give me the Sketch Map for me to understand?
3) I want to know the difference between Data Input Voltage and Enable G Input Voltage;
4) As you reply in question 3), I have the question that min VIH is so low, due to the RS 422 require the min voltage from Drive is 2V; as you know, the PCB layout and cable from the Am26LS31 to relevant Receiver will has the voltage loss,the design for us is using the AM26LS31 to driving the optocouple aiming at Signal isolation;could you please tell me the true min output voltage for VIH, 2V seems so small to drive the optocouple
Hello ,
For Vih, if input voltage is higher than (>=) 2v(min value) , the voltage is recognized as high level;
For Vil, if input voltage is lower than (<=) 0.8v(max value), the voltage is recognized as low level;
output voltage are defined at Voh Vol,
Sorry, Maybe I write the wrong, I write the question again:
if the VCC is 5V, when input voltage is higher than (>=) 2v(min value); Nornally, I think the output voltage may not the 2.5V( min) of VOH, could you please tell me the condition this IC will output the 2.5V VOH? Due to 2.5V seems a little small for us to drive the optocouple;as you know, the PCB layout and cable from the Am26LS31 to relevant Receiver will has the voltage loss,the design for us is using the AM26LS31 to driving the optocouple aiming at Signal isolation;could you please tell me the true min output voltage for VIH, 2V seems so small to drive the optocouple
您好,
数据手册中的技术指标是基于TEST CONDITIONS 测试条件给出的指标,根据具体测试项目不同,提供相应的参数(最小 典型 最大)。
不清楚您关注的哪个最小值没有测试条件,除数据手册中提供的信息无其他信息提供。
