Overview
The LM2901T14-13 is a quad differential comparator manufactured by Diodes Incorporated, housed in a TSSOP-14 package. It operates from a single supply of 2V to 36V or split supplies of ±1.0V to ±18V. The device features a typical input offset voltage of 2mV and a maximum of 15mV across the full temperature range. Supply current is 0.9mA at 5V and 1.2mA at 30V. Input bias current is typically 25nA with a maximum of 500nA. Response time is 1.3µs. The output is open-collector, compatible with TTL, MOS, and CMOS logic.
Feature Summary
- Wide power supply range supporting single and dual configurations
- Low input bias current for minimal loading on signal sources
- Open-collector outputs allow wired-AND logic connections
- Direct interface compatibility with standard digital logic families
Applications
- Level detection circuits
- Window comparators
- Logic level shifting between different voltage domains
- Pulse generation and timing applications
Procurement Notes
Verify the specific ordering suffix -13 confirms tape and reel packaging containing 2500 units per reel. Confirm the T14 designation matches the required TSSOP-14 physical footprint and pinout dimensions. Ensure the component grade corresponds to the standard offset voltage specifications rather than the A-suffix low offset variant.
Selection Notes
Select this part when four independent comparators are required in a compact surface-mount package. The wide common-mode input range including ground makes it suitable for single-supply sensing. Consider the A-suffix version if tighter offset voltage tolerances are necessary for precision applications.
Part Context
This component belongs to the LM2901/2903 series of precision voltage comparators designed for general-purpose analog-to-digital conversion interfaces. The series offers industry-standard pinouts for easy replacement in existing designs. It provides a cost-effective solution for multi-channel comparison tasks in consumer and industrial electronics.

FAQ
Can the differential input voltage exceed the supply voltage?
Yes, the differential input voltage can be equal to the maximum power supply voltage without damaging the device.
How should unused comparator inputs be handled?
All input pins of any unused comparators should be tied to the negative supply to prevent oscillation.
