Original question:

TLC6C5712-Q1: Combining multiple outputs to supply a single LED

TLC6C5712-Q1: Using 4 output pins to supply LED current

Hi, Team,

The customer has two questions:

  1. Is it ok to tie OUT0, OUT2, OUT6, OUT8 output pins to supply current to a single LED?

  2. When tying multiple outputs to supply current to a single LED, does it have to be either even or odd pin #?
    *e.g., OUT1, OUT3, OUT5, OUT7 or OUT0, OUT2, OUT6, OUT8
    The question is based on  the figure 109 (page 57). 

Could you please answer in yes/no for questions 1 and 2 separately with a reason if possible?

Thanks and Best Regards,
Masaru Oinaga

    1. Is it ok to tie OUT0, OUT2, OUT6, OUT8 output pins to supply current to a single LED? it's ok
    2. When tying multiple outputs to supply current to a single LED, does it have to be either even or odd pin #? both are ok
      *e.g., OUT1, OUT3, OUT5, OUT7 or OUT0, OUT2, OUT6, OUT8
      The question is based on  the figure 109 (page 57). 

    because customer could individulely change the PWM value with at the same time, so they can parallel any output channels they want.
