Overview
The TSM933CUA+T is a dual-channel analog comparator from the TSM92x series, manufactured by Touchstone Semiconductor. It operates on single supplies of 2.5V to 11V or dual supplies of ±1.25V to ±5.5V. Key electrical parameters include a maximum input bias current of 0.001µA, typical output current of 40mA, and maximum static current of 4.5µA. The device features a typical CMRR and PSRR of 80dB, a maximum propagation delay of 12µs, and hysteresis of 50mV. Input offset voltage is 10mV at 2.5V. It is housed in an 8-MSOP package with a surface-mount installation type.
Feature Summary
- Dual-channel configuration for independent signal comparison
- CMOS full-swing TTL-compatible push-pull outputs
- Integrated internal voltage reference for simplified circuit design
- Low quiescent current consumption suitable for battery-powered applications
Applications
- Battery-operated portable electronics
- Threshold detection circuits
- Voltage monitoring systems
- Signal conditioning interfaces
Procurement Notes
Verify component authenticity through authorized distributors as the part status is End-of-Life (EOL) since September 9, 2016. Confirm package integrity upon receipt, specifically checking for damage to the 8-MSOP housing. Ensure compatibility with existing PCB footprints before finalizing procurement decisions due to potential supply chain limitations.
Selection Notes
Select this component when dual independent comparators are required within a compact 8-MSOP footprint. It is suitable for designs needing low power consumption with CMOS-compatible outputs. Verify that the required hysteresis and propagation delay specifications align with the system's timing constraints and noise immunity requirements.
Part Context
This device belongs to the TSM92x family of ultra-low-power comparators. It serves as a direct alternative to Maxim Integrated MAX933 devices, offering identical electrical performance and form factors. The product line is designed for cost-sensitive, low-voltage applications requiring high reliability and minimal power usage.
Replacement Considerations
Public confirmed substitute part numbers include MAX933CUA+T.
