MAX901AESE-T

Overview

The MAX901AESE-T is a quad high-speed, low-power voltage comparator in a 16-pin Narrow SO 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, supporting +5V to +10V analog ranges. It delivers an 8ns typical propagation delay at 5mV overdrive and consumes 18mW per comparator at +5V. The input common-mode range includes the negative rail for ground sensing.

Feature Summary

• Features fast propagation delay of 8ns typical at 5mV overdrive for high-speed data discrimination.
• Provides flexible power supply options including separate analog/digital rails or a single combined supply.
• Includes independent TTL-compatible latch inputs for holding output states (Note: Latch feature excluded on MAX901).
• Offers TTL-compatible outputs optimized for driving low-power Schottky TTL loads.

Applications

• High-speed A/D converters and sampling circuits
• Line receivers and V/F converters
• Threshold detectors and input trigger circuitry
• PWM circuits

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm the 'E' grade corresponds to the -40°C to +85°C temperature range. Check current availability status as older Maxim products may be discontinued or subject to limited supply constraints. Ensure compatibility with existing PCB footprints for the 16-Narrow SO package.

Selection Notes

Select this component when four independent comparators are required without latch functionality. The MAX901 lacks the latch inputs found in the MAX900/MAX902/MAX903 variants. Consider the MAX920x series for newer designs requiring pin-for-pin compatibility with significantly lower power dissipation while maintaining similar speed characteristics.

Part Context

The MAX901 belongs to the MAX900–MAX903 family of high-speed, low-power voltage comparators manufactured by Analog Devices/Maxim Integrated. Unlike the MAX900, MAX902, and MAX903, the MAX901 does not include latch inputs but retains identical performance metrics regarding speed and power consumption. It is designed for applications requiring multiple comparator channels in a compact surface-mount package.

Replacement Considerations

The datasheet recommends the MAX9201, MAX9202, or MAX9203 as replacements for new designs. These parts offer pin-for-pin compatibility with the same speed but half the power dissipation. Verify functional equivalence regarding the absence of latch inputs if replacing a MAX901 variant specifically.
