Overview
The TS3702ID is a micropower dual CMOS voltage comparator manufactured by STMicroelectronics. It features a push-pull output stage, eliminating the need for external pull-up resistors. The device operates on a single supply from 4V to 16V or dual supplies of ±1.35V to ±8V. Key electrical parameters include a typical supply current of 9µA per comparator, an input offset voltage of 5mV, and a response time of 1.5µs for a 5mV overdrive. It is housed in an SOIC-8 package.
Feature Summary
- Push-pull CMOS output stage eliminates the requirement for external pull-up resistors
- Extremely low power consumption with typical supply current of 9µA per comparator
- High input impedance of 10^12Ω with extremely low input bias current of 1pA typ
- Pin-to-pin and functionally compatible with bipolar LM393
Applications
- Battery-powered systems requiring low quiescent current
- General-purpose signal conditioning circuits
- Voltage monitoring applications
Procurement Notes
Verify that the specific ordering suffix matches the required temperature range and packaging format. The 'I' suffix indicates an industrial temperature range of -40°C to +125°C. Confirm the presence of the 'D' suffix for the SOIC-8 plastic micropackage. Ensure compatibility with existing designs referencing the LM393 standard.
Selection Notes
Select this component when a dual comparator with push-pull outputs is needed to save board space compared to open-collector types. It serves as a direct replacement for the LM393 while offering significantly lower power consumption. Consider the 5mV input offset voltage and 1.5µs response time for timing-sensitive applications.
Part Context
The TS3702 series consists of micropower dual CMOS voltage comparators designed to replace traditional bipolar counterparts like the LM393. The TS3702ID specifically denotes the industrial grade version packaged in an SOIC-8 footprint. This family provides high input impedance and fast response times suitable for various analog signal processing tasks.
Replacement Considerations
Functionally compatible with the LM393. Verify pinout alignment during PCB redesign.
