HA17901P-E

Overview

The HA17901P-E is a quad comparator integrated circuit manufactured by Renesas Electronics Corporation, originally based on Hitachi designs. It operates from a single power supply voltage ranging from 2V to 36V. Key electrical characteristics include an extremely low current drain of 0.8mA, a low input bias current of 25nA, and a low input offset voltage of 2mV. The device features a common-mode input voltage range that includes ground, even under single-supply operation. Output saturation voltages are specified at 1mV with 5µA load and 70mV with 1mA load. The component is housed in a PDIP-14 package.

Feature Summary

• Operates from a wide single power-supply voltage range of 2V to 36V
• Common-mode input voltage range includes ground during single-supply operation
• Output voltages compatible with CMOS logic systems
• Features extremely low current drain and low input offset voltage

Applications

• Limit comparators
• Simple A/D converters
• Pulse, square-wave, and time delay generators
• Wide range VCO circuits
• MOS clock timers and multivibrators

Procurement Notes

Verify the specific suffix 'E' against the official Renesas datasheet to confirm environmental compliance or pin compatibility details. Ensure the PDIP-14 package matches the target PCB footprint. Confirm availability status as legacy components may have limited stock or end-of-life notices. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit sources.

Selection Notes

Select this component for applications requiring high-speed comparison with minimal power consumption. The inclusion of ground in the common-mode input range simplifies single-supply circuit design. Consider the output compatibility with downstream CMOS logic when designing interface stages. Evaluate the 2mV offset voltage requirement against the precision needs of the specific signal conditioning task.

Part Context

The HA17901 series belongs to the family of analog mixed-signal ICs produced by Renesas, retaining historical Hitachi semiconductor design heritage. It serves as a general-purpose comparator solution for control systems. The P-E designation indicates the plastic DIP package variant with specific manufacturing attributes defined by the supplier's standard nomenclature for this product line.

Replacement Considerations

Compatible substitutes include the HA17901AP and HA17901AFP variants within the same Renesas portfolio. Other generic quad comparators with similar voltage ranges and pinouts may serve as functional replacements if electrical parameters align with the design requirements.
