Overview
The TSM934ESE+T is a quad, low-voltage, micropower analog comparator manufactured by Silicon Laboratories. It operates from single +2.5V to +11V or dual ±1.25V to ±5.5V supplies. 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 component is housed in a 16-SOIC package with an operating temperature range of -40°C to +85°C.
Feature Summary
- Quad configuration providing four independent comparators within a single integrated circuit
- Push-pull output stages compatible with both TTL and CMOS logic families
- Ultra-low quiescent current consumption suitable for battery-powered applications
- Continuous source current capability of 40mA without crowbar switching glitches
Applications
- Threshold detectors
- Window comparators
- Level translators
- Oscillator circuits
- Battery-powered systems
Procurement Notes
Verify the specific suffix 'ESE+T' corresponds to the extended temperature grade (-40°C to +85°C) and tape-and-reel packaging format. Confirm that the ordering part number matches the required quantity per reel. Ensure compatibility with the 16-SOIC footprint during PCB layout verification.
Selection Notes
Select this component when multiple comparator channels are required in a compact form factor. It is suitable for designs needing high output drive capability and low power consumption. Verify that the input voltage range requirements align with the specified common-mode limits relative to the supply rails.
Part Context
This device belongs to the TSM931-TSM934 family of ultra-low-power comparators. It serves as an alternate source for the MAX931-MAX934 series, maintaining electrical and form-factor identity. The ESE+ variant specifically denotes the industrial temperature range and surface-mount packaging.
Replacement Considerations
The datasheet identifies the TSM934 as electrically and form-factor identical to the MAX934. Designers may consider the MAX934 as a direct substitute if available, ensuring pinout and specification alignment.
