Overview
The MAX9140EXK+T is a single-supply analog comparator from the MAX9140 family, manufactured by Analog Devices/Maxim Integrated. It operates within a supply voltage range of 2.7V to 5.5V and consumes 150µA per comparator at 3V. The device features a propagation delay of 40ns with a 10mV overdrive and includes internal hysteresis for clean switching. It offers rail-to-rail input voltage capability extending beyond the power rails and CMOS/TTL-compatible outputs that swing within 300mV of either supply rail. The component is housed in a 5-pin SC70 package and supports continuous short-circuit fault conditions.
Feature Summary
- Rail-to-rail input voltage range extending beyond both power-supply rails
- Internal hysteresis ensures clean output switching without external resistors
- CMOS and TTL logic compatible outputs pulling close to supply rails
- Continuous short-circuit tolerance on all input and output pins
Applications
- Line Receivers
- Threshold Detectors/Discriminators
- Zero-Crossing Detectors
- Sampling Circuits
Procurement Notes
Verify the specific ordering suffix EXK+T against the manufacturer's current datasheet to confirm the exact package type (SC70) and temperature grade (E-grade). Ensure compatibility with the target PCB land pattern for the 5-pin SC70 footprint. Confirm that the required operating temperature range aligns with the specified -40°C to +85°C limits before finalizing procurement.
Selection Notes
Select this component when a low-power, high-speed comparator is needed for 3V or 5V systems. It serves as an upgrade to industry-standard comparators like the MAX941/MAX942 series. Choose this part if rail-to-rail inputs are required and external pull-up circuitry must be eliminated. It is suitable for portable equipment where space and power consumption are critical constraints.
Part Context
This device belongs to the MAX9140/MAX9141/MAX9142/MAX9144 family of high-speed comparators. While the MAX9140 is a single-channel device, the family also includes dual and quad variants. The MAX9141 variant adds latch enable and shutdown functions not present in the MAX9140. All devices share similar electrical characteristics regarding speed and power consumption.
Replacement Considerations
The datasheet identifies the MAX941, MAX942, and MAX944 as industry-standard comparators that this device upgrades. No other specific substitute part numbers are documented in the provided source material.
