THVD1550: About the difference between THVD1550 and THVD1450.

Part Number: THVD1550
Other Parts Discussed in Thread: THVD1450,

Hi team,

My customer wants to change THVD1450 to THVD1450.
I think there is a difference in the number of nodes in the data sheet, but are there any other differences?
Is it possible to do a replacement?


  • What's the system look like, like the data rate, number of nodes, etc? The major difference between these two device is the operation supply. THVD1450 works with both 3.3V and 5V, while THVD1550 only with 5V. Generally speaking THVD1450 can replace THVD1550 in most of cases.
