6257 General Description

The LM193 consists of two independent precision voltage comparators which were designed specifically to operate from a single power supply over a wide range of voltages.Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground,even though operated from a single power supply voltage.

Application areas include limit comparators, simple analog to digital converters; pulse,squarewave and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates. The LM193 was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the LM193 will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.

Note 1: Short circuits from the output to V+ can cause excessive heating and eventual destruction. When considering short circuits to ground, the maximum output current is approximately 20mA independent of the magnitude of V+.

Note 2: This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the comparators to go to the V+ voltage level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive and normal output states will re-establish when the input voltage, which was negative,again returns to a value greater than -0.3Vdc.

Note 3: 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 less than -0.3Vdc (or 0.3Vdc below the magnitude of the negative power supply, if used).

Note 4: Human body model, 1.5K Ohms in series with 100pF.
