Overview
The TSM924ESE+T is a quad analog comparator from Silicon Labs, housed in a 16-pin SOIC package. It operates on single supplies of +2.5V to +11V or dual supplies of ±1.25V to ±5.5V. The device features an internal 1.182V ±1% reference voltage and push-pull TTL/CMOS-compatible outputs capable of sourcing up to 40mA. Quiescent current is less than 2.5μA per comparator over temperature. Propagation delay is 12μs at 10mV overdrive. Input common-mode range extends from the negative supply rail to within 1.3V of the positive rail.
Feature Summary
- Ultra-low quiescent current consumption across operating temperatures
- Integrated internal 1.182V precision voltage reference
- Push-pull output stages with high continuous source current capability
- Wide input common-mode voltage range including the negative supply rail
Applications
- Threshold detectors
- Window comparators
- Level translators
- Oscillator circuits
- Battery-powered systems
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm the specific suffix indicates tape and reel packaging. Ensure compatibility with existing PCB footprints for the 16-SOIC form factor. Review datasheet specifications for absolute maximum ratings to prevent electrical overstress during integration.
Selection Notes
Select this component when multiple independent comparison functions are required in a compact footprint. The integrated reference simplifies design by reducing external resistor networks. Verify that the 12μs propagation delay meets system timing requirements. Consider the 40mA output drive capability for direct load interfacing without additional buffering stages.
Part Context
This part belongs to the TSM921-TSM924 family of ultra-low-power comparators. It is electrically and form-factor identical to the MAX921-MAX924 series. The E suffix denotes an extended industrial temperature range of -40°C to +85°C. The T suffix specifies tape and reel packaging for automated assembly processes.
Replacement Considerations
The TSM924 is functionally equivalent to the Maxim Integrated MAX924. Designers replacing legacy MAX924 units can utilize this part without schematic modifications due to pin and parameter compatibility.
