Overview
The LM319H/NOPB is a high-speed dual comparator manufactured by Texas Instruments, designed for rapid signal comparison and threshold detection in electronic systems. It features an open-collector output configuration capable of driving various logic families. The device operates within a supply voltage range of 5V to 36V and maintains a typical response time of 80ns under standard test conditions. It is housed in a 14-pin SOIC package suitable for surface-mount applications.
Feature Summary
- High-speed response capability with an 80ns propagation delay for fast signal processing
- Open-collector output design allowing flexible interfacing with multiple logic families
- Wide single-supply voltage operation ranging from 5V to 36V
Applications
- Fast analog-to-digital converter (ADC) interface circuits
- Waveform generation and shaping systems
- Threshold detection and level sensing applications
Procurement Notes
Verify the specific suffix 'H' against official Texas Instruments documentation to confirm the exact temperature grade and package variant, as datasheets may list variations such as M or N. Ensure the component matches the required operating temperature range and pinout configuration for your specific PCB layout before finalizing procurement orders.
Selection Notes
Select this component when high-speed switching is required compared to general-purpose comparators. Consider the open-collector output requirement for external pull-up resistors. Evaluate the 80ns response time against system timing constraints and ensure the 36V maximum supply voltage aligns with the available power rails in the target application design.
Part Context
This part belongs to the LM319 series of dual comparators from Texas Instruments. The series is characterized by its speed and compatibility with standard logic families. The LM319 family serves as a foundational component for analog signal conditioning and digital interface tasks requiring precise and rapid voltage level comparisons.
