Texas Instruments LM193, LM293, LM293A, LM393, LM393A, LM2903, LM2903V Datasheet
The LM193, LM293, LM293A, LM393, LM393A, LM2903 and LM2903V are dual differential comparators that operate from a single supply (2 V to 36 V) or dual supplies. They feature low input bias current (typical 25 nA), low input offset voltage (typical 2 mV), and output currents up to 20 mA. Temperature ranges vary per device, e.g., LM193 from –55 °C to 125 °C.
The document lists ordering codes for various package types (PDIP, SOIC, TSSOP, MSOP, etc.), provides mechanical dimensions for the PW package, and includes an important notice about warranty, availability, and TI’s terms of sale.
