Overview
The TSM934CSE+ is a quad analog comparator in a 16-SOIC package. 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 draws a maximum quiescent current of 8.5µA over temperature. Input voltage range extends from the negative rail to within 1.3V of the positive supply.
Feature Summary
- Quad comparator configuration with integrated 1.182V reference
- Push-pull outputs compatible with TTL and CMOS logic levels
- Ultra-low quiescent current consumption for power efficiency
- High continuous source current capability without crowbar switching
Applications
- Threshold detectors
- Window comparators
- Level translators
- Oscillator circuits
- Battery-powered systems
Procurement Notes
Verify the specific suffix CSE+ against the manufacturer's ordering information to confirm the commercial temperature range and lead-free packaging status. Confirm that the 16-SOIC package dimensions match the design requirements. Check for any product change notices regarding pinout or electrical characteristics updates.
Selection Notes
Select this component when four independent comparators are required in a single package. It is suitable for applications needing a stable internal reference voltage. Ensure the input signal range stays within the specified common-mode limits relative to the supply rails. Verify that the output drive current requirements do not exceed the continuous sourcing capability.
Part Context
This part belongs to the TSM93x family, which is electrically and form-factor identical to the MAX931-MAX934 series. The family includes single, dual, and quad variants. The TSM934 specifically provides four comparators per package, distinguishing it from the single-channel TSM931 and dual-channel TSM932/TSM933 models.

FAQ
Does the TSM934 support adjustable hysteresis via a dedicated pin?
No, the TSM934 does not have a dedicated HYST pin. Adjustable hysteresis must be implemented using external resistors connected to the comparator inputs.
What is the input voltage range specification?
The input voltage range extends from the negative supply rail (V-) to within 1.3V of the positive supply rail (V+).
