Overview
The TSM934ESE+T is a quad micropower analog comparator from Silicon Labs, packaged in a 16-pin SOIC. It operates on single supplies from +2.5V to +11V or dual supplies of ±1.25V to ±5.5V. The device features push-pull TTL/CMOS-compatible outputs capable of sourcing up to 40mA continuously. It includes an internal 1.182V reference and exhibits a propagation delay of 12μs at 10mV overdrive. The input voltage range extends from the negative supply rail to within 1.3V of the positive rail.
Feature Summary
- Quad configuration with integrated 1.182V reference
- Push-pull outputs compatible with TTL and CMOS logic
- Ultra-low quiescent current consumption
- Crowbar-current-free switching for glitch minimization
Applications
- Threshold detectors
- Window comparators
- Level translators
- Oscillator circuits
- Battery-powered systems
Procurement Notes
Verify component authenticity through authorized channels as this part may be subject to obsolescence notices. Confirm package integrity and pin alignment upon receipt. Ensure storage conditions adhere to moisture sensitivity levels specified in the datasheet. Cross-reference ordering information to match specific suffix requirements for tape and reel packaging.
Selection Notes
Select this component when a quad comparator with an internal reference is required for low-power applications. It serves as an alternate source for MAX931-MAX934 devices. Consider the 16-pin SOIC package for board space constraints. Verify that the 40mA output drive capability meets load requirements without exceeding thermal limits.
Part Context
This device belongs to the TSM931-TSM934 family of low-voltage, micropower analog comparators. The family shares electrical and form-factor compatibility with the MAX931-MAX934 series. The TSM934 specifically provides four independent comparators in a single package, distinguishing it from the single (TSM931) and dual (TSM932/TSM933) variants.
Replacement Considerations
The TSM934ESE+T is electrically and form-factor identical to the Maxim Integrated MAX934. Designers replacing legacy MAX934 parts can utilize this Silicon Labs component directly without circuit modification.
