Overview
The TSM932CUA+T is a dual, low-voltage, micropower analog comparator from the TSM93x family. It operates on single supplies of +2.5V to +11V or dual supplies of ±1.25V to ±5.5V. The device features an input voltage range including the negative supply rail and push-pull TTL/CMOS-compatible outputs capable of sourcing 40mA. It includes an internal 1.182V ±2% reference and adjustable hysteresis. Propagation delay is 12µs at 10mV overdrive, with quiescent current under 6µA max.
Feature Summary
- Dual-channel configuration with integrated 1.182V reference
- Ultra-low quiescent current consumption for battery applications
- Adjustable external hysteresis capability via dedicated pin
- Push-pull outputs compatible with TTL and CMOS logic levels
Applications
- Battery-powered systems requiring low supply current
- Threshold detection circuits in 3V or 5V single-supply designs
- Signal conditioning where noise immunity is required via hysteresis
Procurement Notes
Verify component authenticity as this part is discontinued by Touchstone Semiconductor and now manufactured by Silicon Labs. Confirm package integrity and check for End-of-Life notifications. Ensure compatibility with existing MAX932 footprints if replacing legacy components. Validate datasheet revisions for any parameter shifts.
Selection Notes
Select this component for dual-comparator applications needing low power and an internal reference. It serves as a direct electrical and form-factor replacement for the MAX932. Consider the 12µs propagation delay and 40mA output drive when designing interface stages. Verify supply voltage ranges match system requirements.
Part Context
Part of the TSM931-TSM934 family, electrically identical to Maxim's MAX931-MAX934 series. Originally produced by Touchstone Semiconductor, production was transferred to Silicon Labs. The TSM932 specifically provides two comparators in an 8-MSOP package, maintaining industry-standard pinouts for easy migration.
Replacement Considerations
- MAX932CI+ (Maxim Integrated)
- MAX932CPE+ (Maxim Integrated)
