Absolute Maximum Ratings indicate limits beyond which damage may occur. Recommended Operating Conditions indicate conditions

for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and test

conditions, see the Electrical Characteristics.

Refer to RETS193AX for LM193AH military specifications and to RETS193X for LM193H military specifications.

If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.

(4)

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

−0.3V (or 0.3V below the

magnitude of the negative power supply, if used).

(5)

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

and normal output states will re-establish when the input voltage, which was negative, again returns to a value greater than

−0.3V.

(6)

For operating at high temperatures, the LM393 and LM2903 must be derated based on a 125°C maximum junction temperature and a

thermal resistance of 170°C/W which applies for the device soldered in a printed circuit board, operating in a still air ambient. The

LM193/LM193A/LM293 must be derated based on a 150°C maximum junction temperature. The low bias dissipation and the “ON-OFF”
