Overview
The LM2901N/PB is a quad differential comparator manufactured by Texas Instruments, housed in a 14-pin PDIP package. It operates on a single supply voltage ranging from 2 V to 36 V or split supplies of ±1 V to ±18 V. Key electrical specifications include a maximum input offset voltage of 7 mV and an input bias current of 250 nA. The device features open collector/open drain outputs capable of driving TTL and CMOS loads. It supports a response time of 700 ns and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Quad differential architecture for multi-channel signal comparison
- Low power consumption with low input offset voltage
- Open collector/drain output compatibility with standard logic families
Applications
- Level detection circuits
- Low-level sensing applications
- Memory circuit designs
Procurement Notes
Verify the specific suffix 'PB' against the official Texas Instruments datasheet to confirm lead-free compliance and RoHS status. Ensure the ordering part number matches the exact package style and temperature grade required for the design. Cross-reference the manufacturer's latest documentation to confirm availability and any potential obsolescence notices before finalizing procurement plans.
Selection Notes
Select this component when a low-power, low-offset quad comparator is needed for single-supply operation up to 36 V. It is suitable for applications requiring direct interface with digital logic without additional pull-up resistors if open-drain outputs are utilized. Consider the 14-PDIP package for through-hole prototyping or manufacturing requirements where surface-mount options are not feasible.
Part Context
The LM2901 belongs to a family of single-supply quad comparators designed for consumer, automotive, and industrial electronics. It shares functional similarities with the LM339 and LM239 but offers specific performance characteristics regarding offset voltage and bias current. The device is intended for general-purpose analog-to-digital conversion interfaces and threshold detection tasks.
Replacement Considerations
LM2901N: Standard commercial version from Texas Instruments. LM2901DRQ1: Automotive-grade variant with AEC-Q100 qualification.
