MAX900BCPP

Overview

The MAX900BCPP is a high-speed, low-power quad voltage comparator manufactured by Analog Devices Inc. (Maxim Integrated). It features differential analog inputs and TTL-logic outputs with active internal pull-ups. The device operates from a single supply voltage ranging from 5V to 10V. Key electrical specifications include an 8ns typical propagation delay at 5mV overdrive, 18mW power consumption per comparator at +5V, and a maximum input offset voltage of 4mV. It includes independent TTL-compatible latch inputs to hold output states.

Feature Summary

• Features four independent comparators with fast propagation delay for high-speed data discrimination applications.
• Includes independent TTL-compatible latch inputs to maintain output states when driven low.
• Provides differential analog inputs with TTL-logic outputs equipped with active internal pull-ups.
• Supports operation from a single combined supply or separate analog and digital power supplies.

Applications

• Fast A/D converters
• Sampling circuits
• Line receivers
• Voltage-to-frequency (V/F) converters

Procurement Notes

Verify component authenticity through authorized distributors as the MAX900 series is discontinued. Confirm package integrity and pin alignment against SOIC-20 specifications. Review datasheet revision history for any updates regarding manufacturing process changes. Ensure compliance with RoHS standards if required by current design constraints. Validate supplier documentation against official Analog Devices records.

Selection Notes

Select this component for designs requiring high-speed comparison with latching capabilities in a quad configuration. Consider the 8ns propagation delay for timing-critical applications. Evaluate power consumption requirements against the 18mW per comparator specification. Ensure the system supports the 5V to 10V supply range. Verify that TTL-compatible outputs align with downstream logic levels.

Part Context

The MAX900 belongs to the MAX900–MAX903 family of high-speed, low-power voltage comparators. It is specifically the quad-channel variant within this series. The device was manufactured using a process no longer available, leading to its discontinuation status. It serves as a legacy solution for applications previously designed around Maxim's high-speed comparator technology.

Replacement Considerations

The MAX9201/MAX9202/MAX9203 are recommended replacements offering pin-for-pin compatibility with half the power dissipation. Verify functional equivalence regarding latch inputs and propagation delays before substitution.
