Overview
The LM2901PW is a quad differential voltage comparator manufactured by Texas Instruments, housed in a 14-pin TSSOP surface-mount package. It operates from a single supply of 2V to 36V or dual supplies of ±1V to ±18V. Key electrical characteristics include a typical response time of 1.3µs, low input bias current of 25nA, and open-collector outputs compatible with TTL, MOS, and CMOS logic families.
Feature Summary
- Features four independent voltage comparators designed for wide-range single or dual power supply operation.
- Provides open-collector outputs that support wired-AND connection capabilities for logical functions.
- Ensures compatibility with standard digital logic families including TTL, MOS, and CMOS.
- Maintains low power consumption and low input offset voltage for precise signal comparison.
Applications
- General-purpose analog signal comparison circuits
- Voltage monitoring and threshold detection systems
- Logic interface adapters between analog sensors and digital processors
Procurement Notes
Verify the specific suffix 'PW' corresponds to the TSSOP-14 package variant when sourcing. Confirm RoHS compliance status and lead times directly with authorized distributors, as manufacturing sites may vary. Ensure the ordering part number matches the required temperature range and output specifications for your design.
Selection Notes
Select this component for designs requiring multiple independent comparators in a compact surface-mount footprint. The wide supply voltage range accommodates various system architectures. Consider the open-collector output structure when designing pull-up resistor networks for interfacing with downstream logic circuits.
Part Context
This device belongs to the LMx39/LM2901 family of quad comparators from Texas Instruments. It shares functional similarities with the LM139, LM239, and LM339 series but offers specific performance trade-offs regarding speed and offset voltage suitable for general-purpose applications.
Replacement Considerations
- LM2901DR (SOIC-14 package)
- LM2901PWR (TSSOP-14 package)
