Note 1: All device specifications are 100% production tested at TA = +25°C. Limits over the extended temperature range are guar-

anteed by design.

Note 2: Inferred from the VOS test. Both or either inputs can be driven 0.3V beyond either supply rail without output phase reversal.

Note 3: VOS is defined as the center of the hysteresis band at the input.

Note 4: IB is defined as the average of the two input bias currents (IB-, IB+).
