This data sheet introduces the characteristics of four voltage comparators: LM193, LM293, LM393, and LM393A. These voltage comparators can operate in single or dual power supplies, with a wide range of operating voltages. They have low input bias current, low input offset current, low input offset voltage, input voltage range includes ground, differential input voltage range equal to maximum rated supply voltage, low output saturation voltage, and output compatible with TTL, MOS, and CMOS.
The LM193, LM293, LM293A, LM393, LM393A, LM2903 and LM2903V are dual differential comparators offered by Texas Instruments. They operate from a single or dual supply over a wide voltage range and feature low input offset voltage, low bias current, and TTL‑compatible open‑collector outputs.
The document includes detailed electrical characteristics, switching performance, ordering and packaging options, mechanical drawings for various package types, and an important notice covering warranty and usage terms.
| Low input offset voltage (typical) | 2 mV |

The LM193 is specified for operation from –55 °C to 125 °C.
Non‑V LM393 devices are rated for up to 30 V, while V‑suffix devices can handle up to 32 V.
