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 R
S
= 0
, 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
, or V
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+
.
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–
).
