I see most circuits direct drive the ULN2803 Darlington array with 5V, however the datasheet shows VI(on) as 2.4V maximum for a 200mA load. The maximum rating for input voltage is 30V.
I always thought the chip should be driven within the recommended operating conditions. So should I use input resistors to keep the voltage under 2.4V for a 200mA load or is 5V fine?
