Overview
The MAX9108ESD+T is a quad, high-speed, low-power voltage comparator designed for single +5V supply operation. It features a propagation delay of 25ns with 10mV input overdrive and consumes only 1.75mW per channel. The device operates within a supply voltage range of 4.5V to 5.5V and includes internal hysteresis for clean switching. Outputs are TTL-compatible without external pullups. Input common-mode range extends from 200mV below ground to within 1.5V of the positive rail. It is housed in a 14-pin SO package.
Feature Summary
- Incorporates internal hysteresis to ensure clean output switching even with slow-moving input signals.
- Features TTL-compatible outputs that require no external pullup circuitry.
- Offers wide input common-mode range extending from 200mV below ground to near the positive supply rail.
Applications
- Battery powered systems
- A/D converters
- Line receivers
- Threshold detectors/discriminators
- Zero-crossing detectors
Procurement Notes
Verify the specific ordering suffix 'ESD' corresponds to the 14-pin SO package configuration required for your design. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before finalizing procurement plans.
Selection Notes
Select this component when a quad comparator configuration is needed with fast response times and low power consumption. Ensure the application utilizes a single +5V supply and requires TTL-compatible logic levels. Verify that the 14-pin SO package footprint fits the PCB layout constraints.
Part Context
This part belongs to the MAX9107/MAX9108/MAX9109 family of comparators. The MAX9108 specifically provides four channels in a compact package. These devices serve as higher-speed, lower-power upgrades to industry-standard comparators like the MAX907/MAX908/MAX909 series.
Replacement Considerations
The MAX9108EUD+T (TSSOP-14) offers identical electrical performance but requires a different footprint. Direct pin-to-pin replacements within the same package type are not explicitly listed in the provided datasheet.
