Hi Sir,
We have used TL16C550C many years. Now, we want to replace TL16C550C to TL16C550D.
We have a problem. When we tx" FB,FC,FD,FE,FF" code, the RX always receive "00" code.
If the TL16C550D "A01 & RD1" between GND connect cap "40p" . The " FB,FC,FD,FE,FF" code is received correctly.
We used The PCB many years. so we can not modify our PCB layout.
Would you please tell us how to solve this problem & Let me know what's different between TL16C550C & TL16C550D. Thanks a lot.
