Product details

Overview

HPA00330AIDRLR from Texas Instruments is a quad differential comparator IC designed for precision voltage comparison in single-supply industrial and power management systems. It features 0.37 mV typical input offset voltage, 200 µA per comparator supply current, 1 µs response time, ±38 V differential input voltage range, and operates from 2 V to 36 V. It is used in server PSU overvoltage protection circuits where fast, rail-to-rail input capability and robust ESD tolerance (2 kV HBM) are critical.

For engineers reviewing the HPA00330AIDRLR datasheet, HPA00330AIDRLR pinout, HPA00330AIDRLR application, or HPA00330AIDRLR equivalent, this page delivers verified specifications, package mapping to SOIC-14, functional pin definitions, real-world use cases in motor drives and building automation, and two validated alternative parts with documented technical and application differences.

Technical Context

The HPA00330AIDRLR implements four independent open-collector comparators with rail-to-rail input stages capable of accepting common-mode voltages down to ground and up to VCC – 2 V. Its internal architecture includes dedicated ESD clamps enabling 2 kV HBM robustness without external protection.

It supports single-supply operation from 2 V to 36 V with quiescent current independent of supply voltage, and delivers TTL/MOS/CMOS-compatible outputs with 21 mA sink capability and low saturation voltage (≤400 mV at 4 mA).

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad differential comparator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LM2901BDR	Identical electrical specs and SOIC-14 pinout; rated for −40°C to +125°C operating range vs. HPA00330AIDRLR's −40°C to +85°C.	Preferred for under-hood automotive or high-temp industrial enclosures where extended temperature margin is required.	Select LM2901BDR when ambient operating temperature exceeds 85°C; otherwise, HPA00330AIDRLR offers identical performance at lower cost.
LM339DR	Legacy A-version: higher 9 mV max offset, 1.3 µs response, 2–30 V supply range, and no guaranteed 2 kV HBM rating.	Suitable only for non-critical, cost-sensitive consumer applications where speed and precision are secondary.	Choose LM339DR only for legacy redesigns with existing qualification; avoid for new designs requiring reliability or performance headroom.

Compared with LM2901BDR, HPA00330AIDRLR trades 40°C upper temperature margin for optimized cost in commercial-grade applications; compared with LM339DR, it delivers measurable improvements in speed, accuracy, and ruggedness-justifying upgrade in any new design targeting industrial longevity.

FAQ

What is the maximum supply voltage rating for HPA00330AIDRLR?

The absolute maximum supply voltage for HPA00330AIDRLR is 38 V, with recommended operation from 2 V to 36 V. This allows direct use in 24 V industrial systems and 36 V battery-powered tools without regulation. Exceeding 38 V risks permanent damage per TI's Absolute Maximum Ratings table.

Does HPA00330AIDRLR support rail-to-rail input operation?

Yes, HPA00330AIDRLR supports rail-to-rail input common-mode range from GND to VCC – 2 V. Either input can extend to the full VCC level while the other remains within valid range, enabling high-side sensing without attenuation. This behavior is confirmed in Section 6.7 of the datasheet.

Is HPA00330AIDRLR pin-compatible with legacy LM339 devices?

Yes, HPA00330AIDRLR uses the standard SOIC-14 package and matches the pinout of LM339, LM239, and LM2901. TI explicitly states the LM339B series is a drop-in replacement for these parts, including identical terminal numbering and function mapping per Figure 5-1.

What is the typical input offset voltage of HPA00330AIDRLR over temperature?

HPA00330AIDRLR has a typical input offset voltage of ±0.37 mV at 25°C, with a maximum of ±5.5 mV across its −40°C to +85°C operating range. This is verified in Table 6-7 (Electrical Characteristics for LM339B) and Figure 6-8 showing stability across temperature and supply voltage.

Can HPA00330AIDRLR drive a 5 V logic input directly?

Yes, HPA00330AIDRLR's open-collector outputs are compatible with TTL, MOS, and CMOS logic families. When pulled up to 5 V, it sinks up to 21 mA while maintaining VOL ≤ 400 mV at 4 mA-well within standard 5 V logic low-level thresholds (≤0.8 V).
