Table 6. ELECTRICAL CHARACTERISTICS AT 5 V SUPPLY
Typical values are referenced to TA = 25°C, VDD = 5 V, VSS = 0 V, VCM = mid−supply, CL = 50 pF, unless otherwise noted. NCS2252 is
connected to RPULL−UP = 10 kΩ to VDD, unless otherwise noted. Boldface numbers apply from TA = −40°C to 125°C (Notes 10, 11)

10. Refer to ABSOLUTE MAXIMUM RATINGS and APPLICATION INFORMATION for Safe Operating Area.
11. Performance guaranteed over the indicated operating temperature range by design and/or characterization.
12. Typical values are provided for NCS2252 output high−to−low propagation delay. NCS2252 is an open drain comparator. Output low−to−high
propagation delay is a function of the RC time constant, which is dependent on the pull−up resistor.
