DS26LV32AT: Driver and receiver connection

Part Number: DS26LV32AT

Hi team,

Can DS26C31 and DS26LV32 be used together?

Similarly, can ds26lv31 and ds26c32 be used together?

Best Regards,
Amy Luo

  • Hi Amy,

    Yes, both of the driver devices are compatible with both of the receiver devices you mentioned.  These all meet the requirements of RS-422 even though they are designed to operate off of different supply voltages.  If you have any further questions please let me know.

  • Hi Max,

    Thank you for your reply.

    DS26C31 is 5V power supply and DS26LV32 is 3.3V power supply. The typical Voh value of DS26C31 is 3.4V. Will it affect DS26LV32 ?

  • Hi Amy,

    No, this is not an issue.  The DS26LV32 is a differential receiver, so it senses the difference between (+) and (-) inputs rather than the absolute voltage level.  The device is specified to work over a +/-10 V "common mode" voltage range, so as long as the input voltages are within this range communication should work as intended.
