(1) “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is functional, but do not ensure specific performance limits.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) For operating at temperatures above 25°C, the lm392-N must be derated based on a 125°C maximum junction temperature and a
thermal resistance of 122°C/W which applies for the device soldered in a printed circuit board, operating in still air ambient. The
dissipation is the total of both amplifiers—use external resistors, where possible, to allow the amplifier to saturate or to reduce the power
which is dissipated in the integrated circuit.
(4) 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 40 mA for the op amp and 30 mA for the comparator independent of the magnitude of V+.
At values of supply voltage in excess of 15V, continuous short circuits can exceed the power dissipation ratings and cause eventual
destruction.
(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 amplifiers 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 −0.3V (at 25°C).

(2) At output switch point, VO≃1.4V, RS= 0Ωwith V+from 5V to 30V; and over the full input common-mode range (0V to V+−1.5V).
(3) The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the
state of the output so no loading change exists on the input lines.
(4) The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end
of the common-mode voltage range is V+−1.5V, but either or both inputs can go to 32V without damage.

(5) Due to proximity of external components, insure that coupling is not originating via the stray capacitance between these external parts.
This typically can be detected as this type of capacitive coupling increases at higher frequencies.
(6) Positive excursions of input voltage may exceed the power supply level. As long as the other input voltage remains within the common-
mode range, the comparator will provide a proper output state. The input voltage to the op amp should not exceed the power supply
level. The input voltage state must not be less than −0.3V (or 0.3V below the magnitude of the negative power supply, if used) on either
amplifier.
(7) The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be obtained.

Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.

Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
