Overview
The TSM924CSE+ is a quad, low-voltage, micropower analog comparator from Silicon Labs. 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. Input voltage range includes the negative supply rail, extending to within 1.3V of the positive rail. Propagation delay is 12μs at 10mV overdrive. It is housed in a 16-Pin SOIC package with an operating temperature range of 0°C to +70°C.
Feature Summary
- Ultra-low quiescent current consumption for battery-powered applications
- Integrated internal 1.182V reference voltage source
- 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 Comparator Circuits
- Level Translators
- Oscillator Circuits
- Battery-Powered Systems
Procurement Notes
Verify the specific ordering suffix CSE+ corresponds to the commercial temperature range (0°C to +70°C) and 16-Pin SOIC package configuration. Confirm lead-free packaging status as standard for this manufacturer series. Ensure compatibility with existing board layouts designed for the MAX924 family due to electrical and form-factor identity.
Selection Notes
Select the TSM924CSE+ when four independent comparators are required in a single package. Choose this part for designs needing an integrated reference voltage without external components. Consider the 40mA output drive for direct LED or logic interface driving. Verify that the commercial temperature range meets system environmental requirements.
Part Context
This component belongs to the TSM921–TSM924 family of single/dual/quad comparators. It is electrically and form-factor identical to the Maxim Integrated MAX921–MAX924 family. The TSM924 specifically provides four comparators with an internal reference, distinguishing it from the TSM922 which lacks the reference and hysteresis pin.
Replacement Considerations
The TSM924CSE+ is functionally equivalent to the MAX924CSE+.
