TLC5916: Can is use the OE(ED2) "Enable pin" to apply PWM signal?

Part Number: TLC5916

Hello everyone,

i am asking if i can apply PWM signal to my design but i don't see about it in the datasheet, if yes, what is the maximum frequency i can run?

Thanks.

here is the link of the datasheet:

  • Hi Kamel,

    Yes it is OK to apply PWM to OE controlling outputs. But the low pulse should follow switching characteristics in datasheet section 7.7 and 7.8 and Figure 7. Minimum low time should be higher than tof + tor + tPHL3 + tPLH3, which is around 1us, to make sure output establish stabled. Maximum frequency is limited to it and the duty cycle you want to set.
