The q denotes specifications which apply over the full operating

temperature range.

Note 1: Input offset voltage is the maximum required to drive the output to

a low state of 0.5V and high state of 2.5V.

Note 2: Input currents are measured by applying a large positive

differential input voltage. The resulting input current is divided by two to

obtain input current at

∆VIN = 0V.

Note 3: Voltage gain is guaranteed by design, but not tested.

Note 4: Propagation delay is sample tested in production with a large

overdrive. The limit is guard banded to account for the slight increase

(

≈ 500ps) at 20mV overdrive.

Note 5: Common mode input range is the voltage range over which the

differential input offset voltage is less than 20mV. If both inputs remain

inside this common mode range, propagation delay will be unaffected. It

will also be normal if the signal input is below the 1.25V lower limit when

the input transition begins. An increase in propagation delay of up to 10ns

may occur if the signal input is above the upper common mode limit when

the transition begins. Sine wave inputs may not be affected when the peak

exceeds the common mode range if the signal is inside the common mode

range for 10ns before threshold is reached.
