• 隔离RS485收发器 LTM2881-3问题咨询

    您好,
    我使用了LTM2881-3的隔离RS485收发器。开始测试的时候,工作正常,在使用几次以后,无法工作,在测试过程中发现,VCC2的5V电压没有输出了,用万用表测试VCC2管脚对GND2阻抗为2Ω,应该是短路烧毁了,请问会有哪些原因造成这种现象?电路是参照数据手册里的电路。

  • What is the MTBF for the following: - LTM2881 - LTM6275 - LTM8033 - LTM8049 - LTC4364

    We have a prototype design using above components.  Working thru the reliability of the design so we need the MTBF figures of these components.

    Regards

  • RE: ADM2867E RS485 Compliant?

    Hi Neil;

    We have another question is that some RS-485 transceiver chip (such as LTM2881-3) can configure the chip into a reduced slew rate mode for reduced EMI(for LTM2881, it can reduce from 20Mbps to 250kbps for low EMI). Does the chip ADM2867E(25Mbps…

  • RE: LTM2881IV-3?

    Hi,

    Yes, the pin-out for the LTM2881-3 is right, B1,B2 should be connected to GND although they are not tied to GND internally, also K1~K3 must be connected to GND2 by PCB wires.

    Regards,

  • RE: LTM2882 communication issue

    Hello, 

    To implement half duplex communication with the LTM2882, the RS-232 transmitter and receiver lines must be connected together on the PCB. Have you connected the LTM2882-3 T1OUT to R1IN and T2OUT to R2IN on the PCB?

    The LTM2882 is an isolated RS…
