We are using P/N: SN74LVC16244ADGGR
We have not observed any issues but have an application/derating question.
In the datasheet, Section 10.2.2 Detailed Design Procedure, it states 25mA per output and 50mA total for the part.
We are well within 25mA per output, at ~ 10mA per output, some outputs at 50% duty cycle, and some at 100% duty.
We are concerned with total ‘part’ current being limited to 50mA.
We have:
1Y1-1Y4 ~10mA, at 50% duty cycle
2Y1-2Y4 ~10mA, at 50% duty cycle
3Y1-3Y4 ~10mA load on each
4Y1-4Y4 ~10mA load on each
This would be a mean total ‘part’ current of ~120mA.
We are wondering if the 50mA total for the ‘part’ may be for a single set of 4x outputs (4 bits) ?
Can you confirm/clarify?
