TL16C550C: difference beween TL16C550C and PC16550D

Part Number: TL16C550C

Dear Technical support team,

PC16550D and PC16552D are discontinued, so I need to replace below.

What is the difference between PC and TL?

Do you have replacement and spec comparison documentation ?

PC16550DV/NOPB  ⇒ TL16C550CIFN

PC16552DV/NOPB ⇒ TL16C2552IFN

Best Regards,

ttd

  • Hello ttd/

    The PC line up was made from national semi, which TI now owns. The TL was made by TI to be pin to pin with the National Semi devices and be competitive with National Semi at the time.

    The devices should be very similar, the only difference I saw between TL16C550C is that it has an Auto flow control enable(AFE) at MCR[5]
