BU5255HFV-TR

Comparators Overview

The BU5255HFV-TR is a CMOS analog comparator manufactured by ROHM Semiconductor. It features super fast recovery diode characteristics and operates within a supply voltage range of 1.8V to 5.5V. The device provides push-pull output with a typical response time of 1.6µs and input offset voltage maximum of 6mV at 3V. It draws a typical circuit current of 0.0065mA and supports an operating temperature range from -40°C to 85°C (extended to 105°C for the SHFV variant). The component is housed in a compact HVSOF5 package.

Comparators Feature Summary

• Features low operating supply voltage capability for efficient power management
• Provides full swing input and push-pull output for robust signal handling
• Maintains extremely low input bias current to minimize loading effects
• Offers wide operating temperature range options for diverse environmental conditions

Comparators Applications

• Low voltage portable electronic devices requiring high efficiency
• Battery-powered systems utilizing single-supply operation
• General-purpose analog comparison circuits in consumer electronics
• Signal processing interfaces demanding low power consumption

Comparators Procurement Notes

Verify the specific suffix against official ROHM documentation, as variants like SHFV extend temperature ranges. Confirm RoHS compliance status directly from the manufacturer's datasheet. Ensure the ordering part number matches the required package type and tape quantity specifications for your assembly line. Cross-reference the ECCN code EAR99 for export classification requirements.

Comparators Selection Notes

Select this component when a low-power, single-supply comparator is required for battery-operated applications. Consider the BU5255SHFV-TR if operation above 85°C up to 105°C is necessary. Evaluate the 1.6µs response time against system speed requirements. Ensure the HVSOF5 package dimensions fit the PCB layout constraints compared to larger packages.
