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. 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 phenomenon 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. 3. At output switch point, VO=1.4Vdc, RS=0Ω with VCC from 5Vdc to 30Vdc, and over the full input common-mode 4. Due to the PNP transistor inputs, bias current will flow out of the inputs, this current is essentially constant independent of 5. Input common mode of either input should not be permitted to go more than 0.3V negative of ground or minus supply. The the output state, therefore, no loading changes will exist on the input lines. upper limit of common mode range is VCC - 1.5V but either or both inputs can be taken to as high as 30volts without damage. 6. Response time is specified with a 100mV step and 5.0mV of overdrive. With larger magnitudes of overdrive faster response times are obtainable. ORDERING INFORMATION PART NO.

This gives the device oscillation tendencies if the outputs are capacitive coupled to the inputs via stray capacitance. This oscillation manifests itself during output transitions (VOL to VOH). To alleviate this situation input resistors
