Hi team,

Can DS26C31 and DS26LV32 be used together?

Similarly, can ds26lv31 and ds26c32 be used together?

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.

Regards,
Max

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 ?

Best Regards,

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.

Max
