HVDA553-Q1: Searching TI P2P solution to replace HVDA553QDRQ1

Part Number: HVDA553-Q1

Hi Team,

There is a good new that we could DIN HVDA553QDRQ1  ! But HVDA553QDRQ1  is out of stock

Customer is looking for the P2P replacement of HVDA553QDRQ1 !

1. Please help suggest P2P solution, THX

2. And TCAN1044A features faster maximum signalling rate (8Mbps), expanded operational supply range (±10%), and lower loop delay times.
One primary difference is the use of pin 5 which is a NC or Vio ('V') pin for TCAN1044A. If replacing HVDA553, a non-V TCAN1044A should be used so that the SPLIT line will be connected to the NC pin , right? THX

    Hi Kygo,

    Exactly right. A TCAN1044A with a NC for pin 5 (the non-'V' version) would be good for this. The NC pin is an electrical no connect so it is safe to be attached to a signal which was previously used for the SPLIT function. The TCAN1044A will also have much better long-term supply potential so it will be the best recommendation in terms of stock as well. 

    Let me know if you have any more questions.

    Regards,
    Eric Schott
