Key Features
- Single strobed comparator with strobe control pin allowing output to be forced high independently of input voltage, enabling complex gating and multiplexing logic
- Wide dual-supply range up to ±18V (36V total) with 3 mV maximum input offset voltage for precision analog threshold detection in industrial systems
- Open-collector output compatible with various logic families including TTL and CMOS, supporting wired-OR bus configurations without additional gate ICs
Applications
The LM211PE4 is widely used in industrial control panels, analog signal processing boards, and instrumentation where precise voltage threshold detection with enable control is required over a wide ±15V to ±18V dual supply range. Its strobe input and open-collector output make it particularly effective in multi-channel multiplexed comparator arrays and zero-crossing detector circuits operating across -55°C to +125°C temperature ranges.

Frequently Asked Questions
What dual-supply voltage range does the LM211PE4 support, and does it work with standard ±15V industrial rails?
The LM211PE4 operates on dual supplies from ±5V up to ±18V, which directly covers the standard ±15V industrial supply rails used in analog instrumentation and process control without any supply modification.
How does the strobe pin on the LM211PE4 differ from a standard comparator, and what circuit benefit does it provide?
The strobe pin allows the output to be forced to a known high-impedance state independent of the differential input, enabling multiple LM211PE4 comparators to share a single open-collector bus line in a wired-OR configuration, reducing IC count in multi-threshold detection circuits.
What is the maximum input offset voltage of the LM211PE4, and which precision threshold applications can it reliably support?
The maximum input offset voltage is 3,000 µV (3 mV), meaning the LM211PE4 can reliably detect voltage differences above 3 mV, making it suitable for voltage window detectors, battery threshold monitors, and overvoltage protection circuits operating on ±15V rails.
What output structure does the LM211PE4 use, and how should the output be connected when driving a 5V TTL logic input?
The LM211PE4 has an open-collector NPN output that requires an external pull-up resistor to the desired logic supply; connecting a 4.7 kΩ resistor from the output to +5V makes the output directly compatible with 5V TTL and CMOS logic inputs.
