TILM111H/NOPB
Overview
The LM111H/NOPB 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 RTL, DTL, TTL, and MOS logic, with the ability to switch voltages up to 50V at currents as high as 50mA. This metal-can version is rated for the full military temperature range of -55C to 125C, making it suitable for high-reliability environments.
Why Choose This Part
The LM111H stands out due to its versatile output flexibility, featuring both an open-collector and an open-emitter that can be referenced to ground or either supply rail. Its low input bias current of 100nA and the ability to operate in harsh thermal environments (-55C to 125C) make it a robust choice for industrial and aerospace instrumentation. The TO-99 metal can package provides superior thermal dissipation and shielding compared to plastic alternatives.
Applications
Key Specifications
Getting Started
When designing with the LM111H, ensure proper decoupling of the supply rails and note that the output can be referenced independently of the ground pin for flexible level shifting. Since this is a through-hole TO-99-8 metal can part, it is easily integrated into high-reliability prototypes using standard soldering techniques or TO-99 sockets. Consult the datasheet for wiring configurations to achieve specific logic levels for TTL or MOS compatibility.
