Overview
The LM319MX/NOPB is a high-speed dual comparator manufactured by Texas Instruments, housed in a 14-pin SOIC surface-mount package. It operates on a single supply voltage ranging from 5V to 36V or split supplies of ±2.5V to ±18V. The device features an open-collector output capable of driving up to 25mA and is compatible with RTL, DTL, and TTL logic families. Key electrical parameters include a typical response time of 80ns at ±15V, a maximum input offset voltage of 8mV, and a maximum input bias current of 1μA. The operating temperature range extends from 0°C to 70°C.
Feature Summary
- High-speed performance with a typical response time of 80ns for rapid signal comparison.
- Open-collector output design allows direct interfacing with various logic families including TTL and DTL.
- Wide single-supply voltage operation supports integration into diverse power environments.
- Strong drive capability enables direct connection to loads such as relays and indicators.
Applications
- Fast A/D converter interface circuits
- Waveform generation and shaping systems
- Industrial control level detection
Procurement Notes
Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status against the latest manufacturer datasheet. Ensure the SOIC-14 package dimensions match the PCB footprint requirements. Confirm the commercial temperature grade (0°C to 70°C) aligns with the operational environment constraints before finalizing procurement orders.
Selection Notes
Select this component when high-speed signal threshold detection is required within standard industrial temperature limits. The open-collector output simplifies logic interfacing without additional pull-up components if voltage levels are compatible. Consider the 8mV maximum input offset voltage for precision applications requiring accurate threshold determination.
Part Context
This part belongs to the LM319 series of analog comparators produced by Texas Instruments. It serves as a general-purpose solution for applications demanding fast response times and flexible logic compatibility. The device is designed to replace older discrete comparator solutions in compact surface-mount designs.
Replacement Considerations
LM319N/NOPB offers identical electrical specifications but utilizes a through-hole MDIP-14 package instead of the surface-mount SOIC-14 form factor.
