Overview
The MAX908EPD is a quad, high-speed, ultra-low-power voltage comparator designed for single +5V supply operation. It features a typical propagation delay of 40ns with 5mV input overdrive and consumes only 3.5mW per comparator. The device operates within a temperature range of -40°C to +85°C and utilizes a 14-pin Plastic DIP package. Its wide input common-mode range extends from 200mV below ground to within 1.5V of the positive rail.
Feature Summary
- Incorporates internal hysteresis to ensure clean output switching without external resistors
- Outputs are TTL-compatible, eliminating the need for external pullup circuitry
- Inputs and outputs feature short-circuit protection allowing continuous connection to supply rails
Applications
- Battery-Powered Systems
- High-Speed A/D Converters
- Threshold Detectors/Discriminators
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'EPD' corresponds to the required -40°C to +85°C industrial temperature range and 14-pin Plastic DIP packaging. Ensure compliance with RoHS directives as indicated in official documentation before procurement.
Selection Notes
Select this component for applications requiring multiple comparators with low power consumption and high speed on a single supply. Consider the fixed internal hysteresis characteristics when designing threshold circuits. Verify that the TTL-compatible output levels align with the logic requirements of the downstream digital components in the system design.
Part Context
This part belongs to the MAX907/MAX908/MAX909 family of comparators manufactured by Maxim Integrated (now Analog Devices). While the datasheet notes the manufacturing process is no longer available for new designs, the documentation remains valid for existing users. The MAX908 specifically provides four independent comparators in a single package.
Replacement Considerations
The datasheet indicates the manufacturing process is unavailable for new designs. Consult technical support or check for industry second-source equivalents if sourcing for new production.
