Overview
The LM2901D is a quad differential comparator manufactured by Texas Instruments, housed in a 14-pin SOIC surface-mount package. It operates on single or dual power supplies ranging from 2V to 30V (single) or ±1V to ±15V (dual). The device features four independent channels with open-collector outputs compatible with TTL and CMOS logic. Key electrical specifications include a typical propagation delay of 1.3µs, a maximum input offset voltage of 7mV at 30V, and a maximum input bias current of 0.25µA at 5V. It supports an output sink current of up to 20mA and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Integrates four independent differential comparators within a compact 14-SOIC package for space-constrained designs.
- Features open-collector outputs that provide flexibility for interfacing with various logic families including TTL and CMOS.
- Supports wide single-supply operation from 2V to 30V, enabling use in low-voltage and standard industrial applications.
Applications
- Level detection circuits
- Low-level sensing systems
- Memory applications
Procurement Notes
Verify the specific suffix against the manufacturer's latest documentation to confirm pinout compatibility and electrical tolerances. Ensure the selected variant meets the required operating temperature range and supply voltage constraints for the target application environment.
Selection Notes
Select this component when multiple independent voltage comparisons are required in a single integrated circuit. The open-collector output structure allows for wired-AND configurations and easy interface with different logic voltage levels. Consider the 1.3µs response time for timing-sensitive signal processing tasks.
Part Context
The LM2901D belongs to the LMx39/LM2901 family of quad differential comparators designed for general-purpose analog switching. This series is characterized by its ability to operate from a single supply while maintaining compatibility with ground-referenced signals. It serves as a cost-effective alternative to operational amplifiers for non-linear switching applications.
