Overview
The TSM923CUA+T is a single-channel analog comparator from the TSM92x series, manufactured by Touchstone Semiconductor. It features CMOS and TTL-compatible push-pull outputs with a typical output current of 40mA. The device operates on a single supply of 2.5V to 11V or dual supplies of ±1.25V to ±5.5V. Key electrical parameters include a maximum propagation delay of 12µs, a maximum input offset voltage of 10mV at 2.5V, and a typical CMRR/PSRR of 80dB. It incorporates an internal voltage reference and adjustable hysteresis. The component is housed in an 8-MSOP package and supports surface mount installation.
Feature Summary
- Integrates an internal voltage reference for simplified threshold detection without external components.
- Features adjustable hysteresis via a dedicated pin to prevent output oscillation during signal transitions.
- Provides CMOS and TTL-compatible push-pull outputs capable of sourcing and sinking up to 40mA.
Applications
- Threshold detectors
- Window comparators
- Level translators
- Oscillator circuits
Procurement Notes
Verify the manufacturer status as the product data indicates an End-of-Life (EOL) notification dated September 9, 2016. Confirm availability through authorized distributors or secondary markets, as standard stock may be limited. Ensure the specific ordering suffix matches the required tape and reel or cut tape packaging format for your assembly process.
Selection Notes
Select this component for low-power applications requiring a built-in reference and adjustable hysteresis. It serves as a functional equivalent to the MAX923 family. Consider the 8-MSOP package constraints and the 0°C to 70°C operating temperature range when designing for industrial or commercial environments.
Part Context
This part belongs to the TSM92x family of ultra-low-power comparators, which are electrically and form-factor identical to the Analog Devices MAX921-MAX924 series. The family includes single, dual, and quad variants designed for battery-powered systems and low-voltage single-supply operations.
