Vio

Input offset voltage (1)

Tamb = +25°C

Tmin ≤ Tamb ≤ Tmax

At output switch point, VO ≈ 1.4V, RS = 0 with VCC

+ from 5V to 30V, and over the full input common-mode

range (0V to VCC

+ –1.5V).

Iio

Input offset current

Iib

Input bias current (II

+ or I

-) (2)

Tamb = 2.5V

Tmin ≤ Tamb ≤ Tmax

The direction of the input current is out of the IC due to the PNP input stage. This current is essentially

constant, independent of the state of the output, so no loading charge exists on the reference of input lines.
