MAX901ACSE+T

Overview

The MAX901ACSE+T is a high-speed, low-power quad voltage comparator manufactured by Analog Devices Inc./Maxim Integrated. It features four independent channels with TTL-logic outputs and active internal pull-ups. The device operates from a single +5V to +10V analog supply or split ±2.5V to ±5V supplies, consuming approximately 18mW per comparator at +5V. Key electrical characteristics include an 8ns typical propagation delay at 5mV overdrive, a maximum input offset voltage of 2mV, and an input bias current of 6µA. It is housed in a 16-SOIC package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

• Features fast propagation delay suitable for high-speed data discrimination applications.
• Provides flexible power supply options including separate analog and digital rails.
• 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
• Line receivers
• Voltage-to-frequency (V/F) converters
• Threshold detectors

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific ordering suffixes that may indicate packaging variations. Ensure the supplier provides valid traceability documentation. Note that availability may be restricted due to lifecycle status; consult technical support for current stock levels and lead times before finalizing procurement plans.

Selection Notes

Select this component when a quad configuration with TTL outputs is required without latch functionality. Consider the MAX900, MAX902, or MAX903 if integrated latch inputs are necessary for the design. Evaluate the MAX920x series for pin-for-pin compatible alternatives offering reduced power dissipation. Verify that the 16-SOIC package fits the PCB layout constraints and that the 0°C to +70°C temperature range meets environmental requirements.

Part Context

The MAX901 belongs to the MAX900–MAX903 family of high-speed, low-power voltage comparators. Unlike the MAX900, MAX902, and MAX903, the MAX901 does not include TTL-compatible latch inputs. All devices in the family share similar speed and power characteristics but differ in channel count and additional control features. The MAX901 specifically offers four channels in a 16-pin package.
