Overview
The LM119H/NOPB is a high-speed dual comparator manufactured by Texas Instruments. It features a typical response time of 80 ns and a maximum input offset voltage of 4 mV. The device operates within a supply voltage range of 2 V to 36 V, with a maximum rating of 40 V. It supports a quiescent current of 5 mA per comparator and delivers an output current capability of 50 mA. The component is housed in a TO-100 metal can package (TO-99-8 equivalent) designed for through-hole mounting.
Feature Summary
- Dual independent comparator architecture integrated into a single package
- High-speed switching performance with 80 ns typical response time
- Robust output stage capable of sourcing or sinking up to 50 mA
- Wide single-supply operating voltage range from 2 V to 36 V
Applications
- Voltage monitoring systems requiring fast threshold detection
- Peak detectors and sample-and-hold circuits
- Window comparator configurations for signal validation
- Pulse generation and timing control logic
Procurement Notes
Verify the specific suffix 'H' indicates the military/extended temperature grade variant when ordering. Confirm the package style matches the required through-hole footprint. Ensure the supplier provides traceability documentation if the application requires strict quality standards associated with the H-grade designation.
Selection Notes
Select this component when high-speed response is critical compared to standard operational amplifiers used as comparators. Consider the 50 mA output drive capability for direct interfacing with logic gates without additional buffering. Evaluate the 4 mV offset voltage tolerance against the precision requirements of the target circuit design.
Part Context
This part belongs to the LMx19 family of high-speed dual comparators. It serves as a specialized alternative to general-purpose op-amps where propagation delay and saturation recovery times are limiting factors. The device complements the single-channel LM111 and quad-channel LM319 families within the manufacturer's analog signal chain portfolio.
Replacement Considerations
- LM319AM-NOPB
- LM119QML
FAQ
What is the maximum output current capability of the LM119H/NOPB?
The device can source or sink up to 50 mA of output current.
Does the LM119H/NOPB include internal hysteresis?
No, the datasheet does not list internal hysteresis; external feedback components are required for noise immunity.
