Differential Input Voltage

IN(+), VIN(–) ≥ 0V (or V–, if used), Note 6

General Note: Devices are ESD protected; however, handling precautions are recommended.

Note 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 V

V+.

Note 2:

Measured at the output switch point where V

OUT ≅ 1.4Vdc with RS = 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:

The input common-mode voltage, V

IN+, or VIN– must not go below –0.3V. The upper end of the common-mode voltage range is V+ – 1.5V at

°C, but either or both inputs can go to +36Vdc without damage, independent of of V

V+.

Note 5:

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–).
