... Note 1: A heat sink may be required to keep the junction temperature below absolute maximum when the output is shorted indefinitely. Note 2: The LT1492/LT1493 are designed, characterized and expected to meet these extended temperature limits, but are not tested at – and 85 C. Guaranteed I grade parts are available.

... There are no clamps across the inputs of the LT1492/ LT1493 and therefore each input can be forced to any voltage between the supplies. The input current will re- main constant at about 50nA over most of this range ...

... When operating the LT1492/LT1493 on a single 3. supply, the output interfaces directly with most TTL and CMOS logic. The response time of the LT1492/LT1493 is a strong function of the amount of input overdrive as shown in the following photos. These amplifiers are unity-gain stable op amps and not fast comparators, therefore, the logic being driven may oscillate due to the long transition time ...
