Overview
The TSM922CSA+T is a dual micropower analog comparator in an 8-pin SOIC package. It operates on single supplies from +2.5V to +11V or dual supplies of ±1.25V to ±5.5V. The device draws less than 4μA total supply current over temperature. It features push-pull TTL/CMOS-compatible outputs capable of continuous source current up to 40mA. Propagation delay is 12μs at 10mV overdrive. Input offset voltage is ±10mV, and the input common-mode range includes the negative supply rail.
Feature Summary
- Ultra-low quiescent current consumption for battery-powered applications
- Push-pull output stage with high continuous source capability
- Wide single and dual power supply operation range
- Input voltage range extends to the negative supply rail
Applications
- Threshold detectors
- Window comparators
- Level translators
- Oscillator circuits
- Battery-powered systems
Procurement Notes
Verify the specific suffix 'T' indicates tape and reel packaging when sourcing this component. Confirm the 'C' designation corresponds to the commercial temperature range of 0°C to +70°C. Ensure compatibility with the 8-pin SOIC footprint during PCB layout review. Cross-reference the manufacturer's latest documentation for any potential product changes or obsolescence notices prior to final procurement.
Selection Notes
Select this part for low-power dual comparator needs requiring high output drive. It is suitable for 3V or 5V single-supply designs. Consider alternatives if internal reference voltage or adjustable hysteresis via a dedicated pin is required, as these are not present in this specific model variant.
Part Context
This component belongs to the TSM921-TSM924 family of ultra-low-power comparators. It is electrically and form-factor identical to the MAX921-MAX924 series. The family includes single, dual, and quad variants with options for internal references and hysteresis control.
Replacement Considerations
Public confirmed substitute part numbers include TSM922CSA+, TSM922ESA+, and TSM922CUA+. These variants share identical electrical characteristics but differ in operating temperature ranges and packaging formats.
