TMS320DM8147: SATA Activity drive strength

Sushruta Shetty

Part Number: TMS320DM8147

Hi,

I have a requirement to drive two leds from Serial ATA disk 0 Activity LED output of DM8147 Processor.

Will this pin have required drive strength to drive two LEDs, or should I consider using a buffer? Please let me know the drive strength of this pin at your earliest convenience.

Hi Sushruta,

I recommend you to use a buffer.

Sashruta,

It is 6mA. See DM814x datasheet, section 6.2 Recommended Operating Conditions, IOH and IOL
