Overview
The LMV7255M7 is a single general-purpose comparator manufactured by National Semiconductor, now part of Texas Instruments. It features rail-to-rail input capability and an open-drain output configuration. The device is designed for low-voltage operation with a supply voltage range supporting down to 1.8V. It is housed in a compact SC-70-5 surface-mount package, making it suitable for space-constrained applications requiring high-speed signal comparison.
Feature Summary
- Rail-to-rail input stage allows full common-mode voltage range utilization
- Open-drain output simplifies interfacing with various logic families
- Low voltage operation supports systems powered at 1.8V or higher
Applications
- Battery-powered portable electronics
- Threshold detection circuits
- Signal conditioning in low-voltage systems
Procurement Notes
Verify the manufacturer source carefully as National Semiconductor was acquired by Texas Instruments. Ensure the SC-70-5 package matches your PCB footprint requirements. Confirm RoHS compliance status if required for your specific manufacturing standards. Check for any ordering suffixes that may indicate tape-and-reel packaging versus cut tape.
Selection Notes
Select this component when a single comparator with rail-to-rail inputs is needed in a minimal footprint. The open-drain output requires an external pull-up resistor; ensure the system design accounts for this requirement. Consider the operating voltage range to ensure compatibility with the target application's power supply rails.
Part Context
This part belongs to the LMV72xx series of low-voltage comparators from National Semiconductor. The series includes variants with different numbers of channels and output types. The LMV7255 specifically denotes a single-channel device with open-drain output, distinguishing it from push-pull output versions within the same family.
Replacement Considerations
Check for LMV7255MX which shares the same electrical characteristics but may differ in packaging format. Verify pinout compatibility before substituting with other single comparators from the LMV72xx family.
