General Note: Devices are ESD protected; however, handling precautions are recommended.
Note 1:
Note 2:
A short circuit from OUT to V+ can cause excessive heating and damage the device. The maximum short circuit output current (OUT to V–) is
approximately 20mA, independent of V_V+.
Measured at the output switch point where V_OUT ≅ 1.4Vdc with R_S = 0Ω, V+ = 5Vdc to 30Vdc, and over the full input common-mode range
(0Vdc to V+ – 1.5Vdc).
Note 3: The direction of input current is out of the device due to its PNP input.
Note 4:
Note 5:
The input common-mode voltage, V_IN+, or V_IN– must not go below –0.3V. The upper end of the common-mode voltage range is V+ – 1.5V at
25°C, but either or both inputs can go to +36Vdc without damage, independent of of V_V+.
The response time measured using a 100mV input step with 5mV overdrive. With greater overdrive, 300ns can be obtained. See “Typical
Characteristics.”
Note 6: Positive 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 below –0.3Vdc (or 0.3Vdc below V_V–).
