Overview
The MAX901BESE is a high-speed, low-power quad voltage comparator from the MAX900–MAX903 series. It features differential analog inputs and TTL-logic outputs with active internal pull-ups. The device operates on separate analog and digital supplies or a single combined supply. Key electrical parameters include an 8ns typical propagation delay at 5mV overdrive, 18mW power consumption per comparator at +5V, and an input common-mode range that includes the negative rail. It lacks latch inputs found in other family members.
Feature Summary
- Features fast propagation delay for high-speed data discrimination applications
- Provides TTL-compatible outputs with active internal pull-ups
- Supports flexible analog supply voltages ranging from +5V to +10V or ±5V
- Allows ground sensing when powered from a single supply due to input range including the negative rail
Applications
- High-Speed A/D Converters
- Line Receivers
- Threshold Detectors
- Input Trigger Circuitry
- PWM Circuits
Procurement Notes
Verify the specific suffix BESE indicates the -40°C to +85°C temperature range and Narrow SO package. Confirm RoHS compliance status as the datasheet notes the manufacturing process may be discontinued. Check for availability of newer pin-for-pin compatible replacements like the MAX9201 series if long-term supply is required.
Selection Notes
Select this component when four independent comparators are needed without latch functionality. Ensure the design accommodates separate analog (VCC/VEE) and digital (VDD) power domains or utilizes a single +5V supply configuration. Verify that the TTL output drive capability meets the fan-out requirements of the downstream logic circuitry.
Part Context
The MAX901BESE 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. It shares the same performance characteristics regarding speed and power consumption but offers a simplified interface for applications where latching is unnecessary.
Replacement Considerations
For newer designs requiring similar speed with half the power dissipation, consider the MAX9201, MAX9202, or MAX9203 series which are pin-for-pin compatible.
