TILM111H
Overview
The LM111H is a high-performance voltage comparator designed to operate over a wide range of supply voltages, from standard 15V op-amp rails down to a single 5V logic supply. It features a unique output stage capable of driving DTL, RTL, TTL, or MOS logic, and can switch voltages up to 50V at currents as high as 50mA. This specific variant is housed in a TO-99-8 metal can package, providing excellent thermal performance and reliability in harsh environments.
Why Choose This Part
The LM111H offers exceptional flexibility with an output that can be referenced to ground, the negative rail, or the positive rail, allowing it to interface with almost any logic family. Its strobe input allows the output to be disabled regardless of the differential input, and the TO-99 metal package ensures long-term stability and high power dissipation capabilities.

Key Specifications
Getting Started
When designing with the LM111H, ensure proper decoupling of the supply rails (5V to 36V total) and note that the output is open-collector, requiring a pull-up resistor for standard logic levels. The offset balancing pins can be used with a potentiometer to nullify the 3mV maximum input offset for high-precision applications. Prototype using a TO-99 to DIP adapter for compatibility with standard breadboards or evaluation platforms.
