Supply original LM393ADGKR, Linear - Comparators, by Texas Instruments

Description
The LM393B and LM2903B devices are the next generation versions of the industry-standard LM393 and LM2903 comparator family.
These next generation B-version comparators feature lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, lower propagation delay, and improved 2 kV ESD performance and input ruggedness through dedicated ESD clamps.
The LM393B and LM2903B can drop-in replace the LM293, LM393 and LM2903, for both "A" and "V" grades. All devices consist of two independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Quiescent current is independent of the supply voltage.
