LM193AH-QMLV National Semiconductor Corporation, LM193AH-QMLV Datasheet - Page 5

• Manufacturer Part Number: LM193AH-QMLV
• Description: Low Power Low Offset Voltage Dual Comparators
• Manufacturer: National Semiconductor Corporation

Electrical Characteristics
Note 5: 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 change exists on the reference or input lines.
Note 6: The input common-mode voltage or 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 V
Note 7: The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be obtained, see typical performance
characteristics section.
Note 8: Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the compara-
tor will provide a proper output state. The low input voltage state must not be less than −0.3V (or 0.3V below the magnitude of the negative power supply, if used).
Note 9: At output switch point, V
Note 10: Refer to RETS193AX for LM193AH military specifications and to RETS193X for LM193H military specifications.
