Overview
The MAX9142ESA+ is a dual high-speed comparator optimized for 3V and 5V single-supply systems. It features rail-to-rail inputs, internal hysteresis, and CMOS/TTL-compatible outputs. Operating within a supply voltage range of 2.7V to 5.5V, it delivers a propagation delay of 40ns with a typical supply current of 150µA per channel. The device operates from -40°C to +85°C in an 8-pin SO package.
Feature Summary
- Rail-to-rail input voltage range extending beyond power-supply rails
- Internal hysteresis ensures clean output switching without external resistors
- Outputs pull to within 0.3V of either supply rail without external pullup circuitry
- All pins tolerate continuous short-circuit faults to either supply rail
Applications
- Line Receivers
- Threshold Detectors/Discriminators
- Zero-Crossing Detectors
- Sampling Circuits
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Confirm that the component matches the exact manufacturer part number required for your design. Ensure compatibility with your PCB land pattern specifications before finalizing procurement decisions.
Selection Notes
Select this component for applications requiring fast response times and low power consumption in portable equipment. It serves as a direct upgrade to industry-standard comparators like the MAX942. Verify that the dual-channel configuration meets system requirements, noting that latch and shutdown functions are exclusive to the MAX9141 variant.
Part Context
This device belongs to the MAX914x family of low-power, high-speed comparators designed for 3V and 5V systems. The MAX9142 specifically provides two independent channels in an 8-pin package. It replaces older generations such as the MAX942, offering improved speed and lower power consumption while maintaining compatibility with standard logic families.
Replacement Considerations
The datasheet identifies the MAX942 as an industry-standard comparator upgraded by this device.
