MAX901BESE-T

Overview

The MAX901BESE-T is a quad high-speed, low-power voltage comparator in a 16-pin SOIC package. It features differential analog inputs and TTL-logic outputs with active internal pull-ups. The device operates from separate analog and digital supplies or a single combined supply ranging from +5V to +10V (or ±5V). Key electrical parameters include an 8ns typical propagation delay at 5mV overdrive, 2mV maximum input offset voltage, and 6µA maximum input bias current. Power consumption is typically 18mW per comparator at +5V. The component supports an industrial temperature range of -40°C to +85°C.

Feature Summary

• Features fast propagation delay for high-speed data discrimination applications
• Provides flexible power supply options including separate analog/digital rails or single supply operation
• Includes TTL-compatible outputs optimized for driving low-power Schottky TTL loads
• Analog input common-mode range extends to the negative supply rail for ground sensing

Applications

• High-speed A/D converters and sampling circuits
• Line receivers and threshold detectors
• Voltage-to-frequency (V/F) converters
• Input trigger circuitry and PWM circuits

Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when sourcing. Confirm the 'E' grade corresponds to the -40°C to +85°C operating range. Ensure compatibility with existing board layouts as the datasheet notes this family is not recommended for new designs due to manufacturing process availability. Check for RoHS compliance status on current stock.

Selection Notes

Select this part for applications requiring quad comparators with TTL outputs and latch-free operation. The MAX901 lacks the latch inputs found in the MAX900/MAX902/MAX903 variants. Consider the MAX9201/MAX9203 series for newer designs offering pin-for-pin compatibility with reduced power dissipation. Evaluate layout requirements carefully due to high gain-bandwidth product sensitivity.

Part Context

The MAX901 belongs to the MAX900–MAX903 family of high-speed, low-power voltage comparators manufactured by Analog Devices / Maxim Integrated. Unlike other members of the series, the MAX901 does not include independent TTL-compatible latch inputs. It shares the same performance characteristics regarding speed and power consumption as the latched versions but offers a simplified interface for continuous comparison tasks.

Replacement Considerations

The datasheet recommends the MAX9201, MAX9202, or MAX9203 for new designs. These parts offer pin-for-pin compatibility with the MAX90x series while providing half the power dissipation.
