SN74AVC4T774: Connecting two outputs for extra current

Part Number: SN74AVC4T774

Support Path: /Other topics/Design techniques and how-to guides/

I am in need of additional current for an SN74AVC4T774 output.  Is there any reason why I shouldn't connect two buffers together?  I would connect both pairs of I/O together on side A and side B.  I would connect both direction signals together as well.

So, for instance, I would connect A1&A2, B1&B2, DIR1&DIR2.  I need the extra current when B1&B2 are outputs.  Does anyone see a downside to doing this?

  • Hey JAinPA,

    This should work as long as you have the inputs being driven by the same source, which is how you've described it so that should be fine. The major downside here is that you'll be losing a channel for other I/O. I would consider that you should get a buffer for your application, but if you are ok using the channel for this and not I/O then you should be able to make this work.

    Best Regards,
    Nick
