Input B (+) General Description The TS393 is dual independent precision voltage comparators capable of single-supply or split-supply operation. The specifications as low as 2.0 mV make this device an excellent ground level with single-supply operation. Input offset- voltage selection for many applications in consumer automotive, and It is designed to permit a common mode range- to- industrial electronics.

T 260 C LEAD Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected. Note 1.

The max. Output current may be as high as 20mA, independent of the magnitude of V , output short circuits CC to V can cause excessive heating and eventual destruction. CC 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 V voltage level (or ground if CC 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, V =1.4Vdc, R =0 with V from 5Vdc to 30Vdc, and over the full input common-mode O S CC 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 V - 1.5V but either or both inputs can betaken to as high CC 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. 2/2 Version: A09
