Note 1. The max. Output current may be as high as 20mA, independent of the magnitude of VCC, output short circuits

to VCC can cause excessive heating and eventual destruction.

Note 2. This magnitude of input current will only occur if the input leads are driven more negative than ground or the

negative supply voltage. This is due to the input PNP collector base junction becoming forward biased acting

as an input clamp diode. There is also a lateral PNP parasitic transistor action on the IC chip. This

phenomena can cause the output voltage of the comparators to go to the VCC voltage level (or ground if

overdrive is large) during the time the input is driven negative. This will not destroy the device and normal

output states will recover when the inputs become -0.3V of ground or negative supply.

Note 3. At output switch point, VO=1.4Vdc, RS=0Ω with VCC from 5Vdc to 30Vdc, and over the full input common-mode

Note 4. Due to the PNP transistor inputs, bias current will flow out of the inputs, this current is essentially constant

independent of the output state, therefore, no loading changes will exist on the input lines.

Note 5. Input common mode of either input should not be permitted to go more than 0.3V negative of ground or minus

supply. The upper limit of common mode range is VCC - 1.5V but either or both inputs can betaken to as high

as 30volts without damage.

Note 6. Response time is specified with a 100mV step and 5.0mV of overdrive. With larger magnitudes of overdrive

faster response times are obtainable.
