Overview
The HA17901PJ-E is a quadruple comparator integrated circuit manufactured by Renesas Electronics Corporation. It operates from a single power supply voltage ranging from 2V to 36V, featuring extremely low current drain of 0.8mA. The device includes ground within its common-mode input voltage range and offers low input bias current (25nA), low input offset current (5nA), and low input offset voltage (2mV). Output saturation voltage is specified at 1mV for 5µA and 70mV for 1mA. The output voltages are compatible with CMOS logic systems.
Feature Summary
- Quadruple comparator configuration designed for power or control systems
- Wide single power-supply voltage operation range from 2V to 36V
- Common-mode input voltage range includes ground potential
- Output compatibility with CMOS logic systems
Applications
- Limit comparators
- Simple A/D converters
- Pulse/square-wave/time delay generators
- Wide range VCO circuits
- MOS clock timers
Procurement Notes
Verify the specific suffix PJ-E against official Renesas documentation to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives as indicated in current datasheets. Confirm availability status directly with authorized distributors or Renesas sales teams, as component lifecycle status may vary. Request security documentation via NDA if required for automotive or high-security applications.
Selection Notes
Select this component for applications requiring multiple independent comparison functions within a single package. Consider the wide supply voltage range and ground-referenced inputs for flexible circuit design. Evaluate the low power consumption characteristics for battery-operated or energy-efficient systems. Verify that the output drive capability meets the requirements of the downstream CMOS logic interface.
Part Context
The HA17901 series belongs to Renesas' portfolio of analog comparator ICs, historically derived from Hitachi Semiconductor designs. These devices are engineered for general-purpose signal processing and control tasks. The quadruple configuration allows for complex logic implementation without occupying excessive board space. Renesas continues to support these legacy parts for existing industrial and consumer electronics designs.
Replacement Considerations
Compatible substitutes include HA17901A, HA17901AFP, and HA17901AP. Verify pinout compatibility and electrical parameter tolerances before substitution. Ensure the alternative part number matches the required package style and operating temperature range.
