Overview
The LM2901DRCT is a quad differential comparator integrated circuit manufactured by Texas Instruments, housed in a 14-pin SOIC surface-mount package. It operates on a single or dual power supply ranging from 2V to 30V. The device features an open-collector output type compatible with CMOS and TTL logic families. Key electrical parameters include a typical response time of 1.3µs, an input offset voltage of 7mV, and an operating temperature range from -40°C to +125°C.
Feature Summary
- Quad differential architecture providing four independent comparison channels within a single component.
- Open-collector output configuration ensuring compatibility with various logic standards including CMOS and TTL.
- Wide single-supply operational capability supporting voltages from 2V up to 30V.
Applications
- General-purpose analog signal comparison circuits
- Industrial temperature monitoring systems
- Over-voltage protection detection
Procurement Notes
Verify the specific suffix 'CT' corresponds to Cut Tape packaging when sourcing. Confirm the manufacturer is Texas Instruments to ensure correct specifications. Check RoHS compliance status for environmental regulations. Validate the 14-SOIC package dimensions against PCB footprint requirements. Ensure the operating temperature range meets system thermal constraints.
Selection Notes
Select this component when multiple independent comparisons are required in a compact surface-mount design. The wide supply voltage range suits diverse power environments. Verify that the 1.3µs response time aligns with signal speed requirements. Consider the open-collector output needs for external pull-up resistors. Evaluate thermal performance within the specified industrial temperature range.
Part Context
This part belongs to the LM2901 series of analog comparators. It shares functional similarities with other quad comparators but offers specific differential input characteristics. The SOIC-14 package provides a balance between pin count and board space efficiency compared to larger packages.
Replacement Considerations
LM2901DR is the standard reel variant with identical electrical specifications. LM2901NSR offers the same functionality in a tape-and-reel format. LM2901PWR serves as a pin-compatible alternative in a TSSOP-14 package.
