SN74ABT245B: Layout questions

Part Number: SN74ABT245B

customer want to sink 28mA current on 5 channels (sum 135mA). Is this ok? Do he has to take care on the layout?

Regards, Holger

  • Hi Holger,

    The ratings given in the datasheet are for each single pin and not for the sum of all the pins. When the output of a pin is low, it can sink 64mA according to the datasheet. This means there shouldn't a problem sinking 28mA when the device drives low.
