Other Parts Discussed in Thread: LSF0108
Dear teams,
I used TXB0108 drive relay,the circuit diagram is as follows:
I cannot drive the relay in actual use, and I feel that the driving ability is insufficient.
I was able to drive relays…
如题,下图为我的电路设计图。我想使用LSF0108进行1.8v(a侧)到3.3v(b侧)的转换,但当我使用示波器测量时,b侧电压仍保持1.8v。请大家帮我看看电路或者器件使用有什么问题吗?
As the subject, the following is my circuit design drawing. I wanted to convert 1.8v (A side…
i convert the LSF0108's IBIS model to pspice model,found that LSF0108's each pin is one single component,makes me can't use it to draw schematic,and run function simulate.how can i solve it?
Hi,team
我们在调试LSF0108的时候遇到了一个问题。原理图如图所示。
UART1是主板传输过来的串口信号,1.8V电平,位于左边的A端口。希望转换为3.3V后从B端口输出。下图是U10没有上电,在A端口测出的UART1原始波形——
下图是U10上电后,在A端口测出的UART1波形——
可以发现,U10没有上电时,UART原始波形是正常的,但U10上电后,低电平就拉不下来了,按道理低电平应该…
The LSF0108 automatic bidirectional level conversion IC is used in the new project , and I would like to ask about its design. The circuit is shown in the figure.
Question 1: Handling of EN pins
Now it is the combination of EN and…
在application report中看到LSF010x的基本框图,但是框图中没有标明MOSFET的源极和漏极,请问和vrefA相连的是源极还是漏极?VBPU是起到什么作用?芯片是如何通过两个MOSFET实现了自动双向电压转换?
LSF0108RKSR做信号的电平转换器,效果不太理想,在50MHz频率下波形失真较大. 请问有解决方案吗?或者是有其他型号推荐!!
要求:
1.时钟频率最高达208MHz。
2.支持1.8V和3.3V电平转换,双向数据传输
搭建了一个5V和3.3V的双向电平转换电路,如图显示,调试过程中发现3.3V被拉高到3.9V,断开EN控制脚后,电压恢复正常的3.3V,5V供电电压正常,请问问题出在哪里?
