Overview
The LM393TL/NOPB is a dual low-power voltage comparator manufactured by Texas Instruments, housed in an MSOP-8 surface-mount package. It features two independent high-gain comparators designed for single or dual power supply operation ranging from 2V to 36V. The device offers a typical response time of 1.3 microseconds and operates within a commercial temperature range of 0°C to +70°C. Key electrical characteristics include a maximum input offset voltage of 5mV and a quiescent current of approximately 200µA per channel.
Feature Summary
- Dual-channel architecture providing two independent precision voltage comparators in a compact footprint
- Open-collector output structure compatible with various logic families including TTL and CMOS
- Low power consumption design suitable for battery-operated applications
- Wide single-supply operating voltage range supporting diverse system requirements
Applications
- Over-voltage and under-voltage detection circuits
- Temperature sensing and control systems
- Waveform generation and shaping
- Logic level shifting between different voltage domains
Procurement Notes
Verify the specific suffix TL indicates the MSOP-8 package variant distinct from standard SOIC or DIP versions. Confirm RoHS compliance status as indicated by the NOPB designation. Ensure the ordering part number matches the required tape-and-reel quantity specifications for automated assembly processes.
Selection Notes
Select this component when a small surface-mount form factor is required compared to traditional through-hole packages. Consider the open-collector output requirement which necessitates external pull-up resistors for proper logic level interfacing. Evaluate the 1.3µs response time against application speed requirements to ensure adequate performance margins.
Part Context
This device belongs to the LM393 family of dual comparators, widely used in industrial and consumer electronics. The NOPB suffix denotes a lead-free and RoHS-compliant version of the original LM393TL. It serves as a direct replacement for legacy LM393 variants while offering improved environmental compliance and consistent manufacturing quality standards.
