MAX901ACPE

Overview

The MAX901ACPE is a quad high-speed, low-power 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 separate analog and digital power supplies or a single combined supply ranging from +5V to +10V for the analog section, while the digital supply requires +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 consumes approximately 18mW per comparator at +5V. The component is housed in a 16-pin Plastic DIP 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 analog supply options including single or split rail configurations
• Includes TTL-compatible outputs optimized for driving low-power Schottky TTL loads
• Supports ground sensing when powered from a single supply due to negative rail input range

Applications

• High-speed A/D converters
• Line receivers
• Voltage-to-frequency (V/F) converters
• Threshold detectors
• Input trigger circuitry

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific manufacturing lot codes if required for legacy system maintenance. Ensure proper handling procedures are followed during installation to prevent electrostatic discharge damage to the sensitive input stages.

Selection Notes

Select this part for designs requiring multiple comparator channels without latch functionality. Note that unlike the MAX900/MAX902/MAX903, the MAX901 lacks independent latch inputs. Consider the MAX920x series for newer designs requiring pin-for-pin compatibility with significantly lower power dissipation.

Part Context

The MAX901ACPE belongs to the MAX900–MAX903 family of high-speed comparators. While it shares performance characteristics with other members of the series, it specifically excludes the latch feature found in the MAX900, MAX902, and MAX903 variants. This makes it distinct within the family for applications needing pure comparison without output holding capabilities.

Replacement Considerations

The datasheet explicitly states the MAX900 was manufactured using a process no longer available and is not recommended for new designs. For newer designs requiring similar speed with half the power dissipation, the MAX9201/MAX9202/MAX9203 series are suggested as replacements.
