    Dual Level converter ICs

    Hi,

    Is there any single IC which contain both the 3.3 to 5 V and 5 to 3.3 V converter. Even some two channels each for both the cases?

    If available pls share me the part number..

    Re: Dual Level converter ICs

    Hi,

    You are asking about two bidirectional signal lines?

    I know the 8 bits wide ICs, don't know if there are two bit wide ICs.
    74lvx3245, or 74lvx4245

    Look at: https://www.fairchildsemi.com/produc...l-translators/
    Ahh, here are 2 bit level converter ICs.

    Thanks..

    FXMAR2102 has 2 channels.

    By the way i am interfacing the 3.3V microcontroller with the 5V Max488 IC. Shall i use this isolator for the TX and RX line between them..

    Controller - RX - Channel 1 of FXMAR2102 - DO - Max488
    Controller - TX - Channel 2 of FXMAR2102 - DI - Max488

    Shall i use like this?

    Hi,

    Why don't you use MAX3488?

    ...there is no isolator....

    Re: Dual Level converter ICs

    But if the A,B,X,Y of Max3488 is connected with another device 5V Max488, then will it not be problem?

    Shall i connect Two devices like this?? one device is having 5V operating Max 488 and another one is having 3.3 V operating Max3488.

    Will it have any issues on doing it so?

    Hi,

    RS485, RS422 are standards. Every device must meet the specifications independent of it's supply voltage.

    If you want detailed information, then reading the datasheets is a good idea:
    MAX3488:
    * -7V to +12V Common-Mode Input Voltage Range
    * Driver Output Voltage (A, B, Y, Z)..........................-7.5V to 12.5V (independent of Vcc)
    * Receiver Input Voltage (A, B) ................................-7.5V to 12.5V (independent of Vcc)
