Overview
The LM361N/NOPB is a high-speed differential comparator manufactured by Texas Instruments, housed in a 14-pin PDIP package. It operates on a single supply voltage ranging from 11 V to 32 V or dual supplies up to ±16 V. The device features a differential input configuration with a strobe function for noise immunity. Key electrical specifications include an input offset voltage of 1 mV maximum, an input bias current of 30 µA, and a response time of 140 ns. The operating supply current is 20 mA, and it functions within a temperature range of 0°C to 70°C.
Feature Summary
- High-speed differential comparison capability with strobe functionality
- Complementary TTL output voltage levels
- Wide single or split power supply operation
Applications
- High-speed analog-to-digital converter interfaces
- Zero-crossing detection circuits
- Fast timing applications requiring precise threshold monitoring
Procurement Notes
Verify the specific suffix N/NOPB against the manufacturer's datasheet to confirm the PDIP-14 through-hole package and lead-free compliance. Confirm the active status or obsolescence notice directly with Texas Instruments, as component lifecycle status can change without immediate distributor updates. Ensure the application environment stays within the specified 0°C to 70°C operating temperature range.
Selection Notes
Select this component when a differential input with strobe control is required for fast signal comparison. The 14-pin DIP package suits prototyping or legacy board designs. Consider the 140 ns response time and 30 µA input bias current for circuit compatibility. Verify that the 11 V minimum supply voltage aligns with the system power architecture before finalizing the design.
Part Context
The LM361 series belongs to Texas Instruments' portfolio of high-speed analog comparators. The LM361N/NOPB variant specifically denotes the plastic dual in-line package version with lead-free termination. This part is designed for applications demanding rapid switching speeds and noise rejection through its integrated strobe feature, distinguishing it from standard non-strobe comparators.
Replacement Considerations
Consult the official datasheet for direct pin-compatible alternatives within the LM361 family, such as the LM361M/NOPB (SOIC package) or LM361MX/NOPB (SOT-23-5 package). Verify functional equivalence regarding response time and supply voltage ranges before substitution.
