electrical characteristics over recommended ranges of supply voltage and operating free-air
temperature (unless otherwise noted) (continued)
outputs − Ports P1 and P2
NOTES: 1. The maximum total current, I OHmax and I OLmax , for all outputs combined, should not exceed ±12 mA to hold the maximum
output frequency − Ports P1 and P2
NOTES: 1. A resistive divider with 2 times 0.5 kW between V CC and V SS is used as load. The output is connected to the center tap of the divider.
