AD53513 is obsolete. Are there any chips applied to pin driver like AD53513?
Thank you for taking interest in our ATE products. The AD53513 is a Quad Ultrahigh-Speed Pin Driver with High-Z and VTERM Modes. Given that, the closest which is now still in production is the ADATE209. To better help, can I have additional info on your target application? Your target output and input ranges would also help me to suggest a better part.
