TLC59282 Daisy Chain circuit problem

Other Parts Discussed in Thread: TLC59282

Hi,

I am using TLC59282 with Daisy Chain to drive 160-200 LEDs, the schematic as follow.

These two schematics are both working, one added RC circuit, the other one without RC circuit. So my question is which design is better, and why? Thank you.

Best regards

Andy

Hi Andy,
It depends on your application(SCLK speed and the number of IC one SCLK drive).
The typical value TD0 of tlc59282 is 8ns, if you think this parameter is short and critical. You can add RC circuit, it may help you especially in cascading series.

Best regards,
Feifei

Are you sure it works when SIN is shorted to GND (the second schematic)?
