General Note
: Devices are ESD protected; however, handling precautions are recommended.
1. 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 VV+.
2. Measured at the output switch point where VOUT 1.4Vdc with RS = 0, V+ = 5Vdc to 30Vdc, and over the full input common-mode range
(0Vdc to V+ – 1.5Vdc).
3. The direction of input current is out of the device due to its PNP input.
4. The input common-mode voltage, VIN+, or VIN– 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 VV+.
5. The response time measured using a 100mV input step with 5mV overdrive. With greater overdrive, 300ns can be obtained. See “Typical
Characteristics.”
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 VV–).
