Pullup resistor 1 kΩ ±15%, 60 mW

This module contains six independent open collector analog comparators and six 1 kΩ resistors to be used as pullup resistors for comparator outputs.

Each comparator has the input to output relationship of table I.

The common mode voltage range is between (−V_CC +0.4 V) and (+V_CC − 1.3 V) when the input common mode voltage exceeds the common mode voltage range, the comparator output may latch at a high level. Test condition R guarantees correct module operation with a minimum common mode voltage of (+V_CC − 1.3 V). TABLE I. Input to output relationship.
