Overview
The LM2901Q4T is a quad voltage comparator manufactured by STMicroelectronics, housed in a 16-VFQFN exposed pad package. It operates from a single supply of +2 V to +36 V or dual supplies of ±1 V to ±18 V. The device features a maximum static supply current of 2.5 mA and supports CMOS, DTL, ECL, MOS, and TTL compatible outputs. It functions within an operating temperature range of -40 °C to +125 °C.
Feature Summary
- Four independent precision voltage comparators designed for wide single-supply operation
- Input common-mode voltage range includes the negative rail
- Outputs compatible with various logic families including CMOS, DTL, ECL, MOS, and TTL
Applications
- Signal conditioning circuits
- Voltage monitoring systems
- Threshold detection applications
Procurement Notes
Verify the specific suffix Q4T against official datasheets to confirm the 16-QFN package and pinout configuration. Ensure compatibility with the required operating temperature range and supply voltage specifications before integration into the design.
Selection Notes
Select this component when four independent comparators are required in a compact surface-mount package. It is suitable for designs needing input common-mode ranges that include the negative rail and flexible output logic compatibility across multiple standards.
Part Context
This part belongs to the LM2901 family of low-power quad voltage comparators. It shares functional similarities with other variants like the LM2901DT but differs in packaging and specific electrical tolerances defined by the manufacturer's quality grades.
Replacement Considerations
LM2901VDR2G is listed as a similar alternative by distributors.
