Overview
The TS3021ILT is a single-channel analog comparator manufactured by STMicroelectronics, housed in a SOT-23-5 surface-mount package. It operates on a single supply voltage ranging from 1.8V to 5V. Key electrical specifications include a maximum propagation delay of 105ns and a typical response time of 38ns. The device features rail-to-rail inputs and push-pull outputs, with a maximum input offset voltage of 6mV at 5V. Static current consumption is typically 73µA, with a maximum of 90µA. It supports an output current of 26mA per channel and functions within a temperature range of -40°C to 125°C.
Feature Summary
- Rail-to-rail input capability for full signal swing utilization
- Push-pull output stage providing defined logic levels
- High ESD tolerance rated at 5kV HBM and 300V MM
- Automotive qualification compliant for robust operation
Applications
- Signal conditioning in industrial control systems
- Event detection in automotive electronic modules
- Voltage threshold monitoring in power management circuits
Procurement Notes
Verify the specific suffix ILT corresponds to the SOT-23-5 package and reel packaging configuration. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the ordering quantity aligns with the standard factory pack size of 3000 units or cut-tape availability if partial reels are supported by the distributor.
Selection Notes
Select this component when a low-power, high-speed comparator is needed in a compact footprint. The TS3021ILT is suitable for designs requiring rail-to-rail input compatibility with low-voltage logic interfaces. Consider its 1.8V minimum supply operation for battery-powered applications where energy efficiency is critical alongside fast switching speeds.
Part Context
The TS3021ILT belongs to the TS3021 family of single comparators from STMicroelectronics. This series is designed to offer an optimal balance between micropower consumption and high-speed response. The family includes variants such as the TS3021H for extended temperature ranges and other packages like SC-70-5, catering to diverse space-constrained design requirements.
Replacement Considerations
Direct substitutes within the same family include TS3021ICT (SC-70-5 package) and TS3021HIYLT (SOT-23-5 package). Verify pinout compatibility and thermal performance characteristics before swapping, as package dimensions and thermal dissipation capabilities may differ between SOT-23-5 and SC-70-5 form factors.
