Input Offset Voltage - note 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 common-mode range (0V to V

+ -1.5V).

Iib

Input Bias Current (I+ or I-) - note 2)

Tamb = +25°C

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.

Input Common Mode Voltage Range - note 3)

VCC = 30V

Tamb = +25°C

Tmin ≤ Tamb ≤ Tmax

The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the

common-mode voltage range is VCC

+ -1.5V, but either or both inputs can go to +30V without damage

Response Time - note 5)

RL= 5.1kΩ connected to VCC

Posistive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the

comparator will provide a proper output state. The low input voltage state must not be less than -0.3V (or 0.3V bellow the negative power supply, if

used).
