Hi,

I'm trying to use the AM26LS32ACDRG4 as a direct replacment for the DS26LS32ACM, however the output is not TTL. As per below  (AM26LS32ACDRG4  was connected in parallel to DS26LS32ACM)

Green -> Output from DS26LS32ACM (OUT A / PIN3)

Yellow-> Output from AM26LS32ACDRG4 (OUT A / PIN3)

Schematic is as per below:

Any advice why I'm getting such output ?
