The LM111 is an 8-pin dual in-line package (CDIP) integrated circuit (IC) that serves as a general-purpose comparator. It is designed to compare two voltage inputs and provide a digital output based on the voltage relationship.

The LM111 consists of a single comparator element, making it suitable for applications requiring one-to-one voltage comparisons. It offers multiple output types, including DTL (Diode-Transistor Logic), MOS (Metal-Oxide-Semiconductor), open-collector, open-emitter, RTL (Resistor-Transistor Logic), and TTL (Transistor-Transistor Logic). This flexibility allows the IC to be compatible with various logic families.

The LM111 can be powered by a single voltage source ranging from 5V to 36V or dual supplies with a voltage range of ±2.5V to ±18V. This wide voltage supply range enables its usage in different power systems.

To ensure accurate comparisons, the LM111 has a maximum input offset voltage of 3mV when operated with ±15V supplies. It exhibits low input bias current, with a maximum of 0.1µA when subjected to ±15V input voltages.

The IC has a quiescent current of up to 6mA and operates reliably over a wide temperature range from -55°C to 125°C. Its 8-CDIP package with a lead spacing of 0.300 inches (7.62 mm) facilitates through-hole mounting, making it suitable for integration into various electronic systems.

Although specific values for characteristics such as propagation delay, hysteresis, common mode rejection ratio (CMRR), power supply rejection ratio (PSRR), and output current are not provided, the LM111 can be expected to deliver typical performance for a general-purpose comparator.

Overall, the LM111 is a versatile general-purpose comparator IC that can compare voltage inputs and provide digital outputs compatible with multiple logic families. With its wide supply voltage range, low input offset voltage, and low input bias current, it is suitable for a range of applications where accurate voltage comparisons are required.
