(1)

The unused inputs must be held high or low to prevent them from floating.

(2)

The dc input signal voltage specifies the allowable dc execution of the differential input.

(3)

The differential input signal voltage specifies the differential voltage |VTR – VCP| required for switching, where VTR is the true input

level and VCP is the complementary input level.

(4)

over recommended operating free-air temperature range (unless otherwise noted)
