4) AL output
AL output is an open collector and requires pull-up resistor.
The IC can be protected by adding resistor R1. An excess of absolute maximum rating, when AL output terminal is
directly connected to power supply, could damage the IC.

● Calculation of power consumed by IC
Vcc
Power consumed by this IC Pc is approximately calculated as follows:
Icc
AL
IAL
Pc=Pc1+Pc2+Pc3
? Pc1 ： Power consumption by circuit current
Pc1=Vcc×Icc
? Pc2 ： Power consumption at output stage
Pc2=VOL×Io+VOH×Io
VOL is L voltage of output terminal 1 and 2.
VOH is H voltage of output terminal 1 and 2.
Io is the current flowing to output terminal 1 and 2.
? Pc3 ： Power consumption at AL
Pc3=VAL × IAL
OUT1
Io
OUT2
Fig.15 Calculation of power consumed by IC
VAL is L voltage of AL output.
IAL is the current of AL.
Power consumption by IC greatly changes with use condition of IC such as power supply voltage and output current.
Consider thermal design so that the maximum power dissipation on IC package is not exceeded.
