Product details
Overview
HA1631D02TEL-E from Renesas is a dual CMOS comparator with push-pull full-swing outputs, low supply current (100 µA typ per comparator), 1.8–5.5 V single-supply operation, and input common-mode range extending to ground. It delivers fast response (TPLH = 0.33 µs, TPHL = 0.17 µs at 100 mV overdrive, CL = 15 pF) and supports direct interfacing with TTL/CMOS logic in battery-powered sensor monitoring and portable power management circuits.
For engineers reviewing the HA1631D02TEL-E datasheet, HA1631D02TEL-E pinout, HA1631D02TEL-E application, or HA1631D02TEL-E equivalent, this page provides verified electrical specifications, package mapping to TSSOP-8, confirmed dual-channel comparator functionality, output drive capability (IOSOURCE = 13 mA, IOSINK = 14 mA), and validated alternatives for low-power analog threshold detection designs.
Technical Context
The HA1631D02TEL-E implements two independent high-precision comparators in a single die, each featuring rail-to-rail input stage with ground-sensing capability and push-pull output stage capable of sourcing 13 mA and sinking 14 mA. Its architecture avoids internal hysteresis, enabling clean zero-crossing detection when externally configured.
Designed for ultra-low-power systems, it achieves 100 µA typical supply current per comparator at 3.0 V while maintaining 5 mV max input offset voltage and 1 pA typical input bias current - critical for high-impedance sensor interfaces such as thermistor or photodiode front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.8 V to 5.5 V - enables direct use with Li-ion, 3.3 V, and 5 V rails without level-shifting. |
| Supply current (typ) | 100 µA per comparator - supports multi-year battery life in always-on wake-up circuits. |
| Input offset voltage (max) | 5 mV - ensures reliable detection of small differential signals (e.g., ±10 mV thresholds). |
| Input bias current (typ) | 1 pA - preserves signal integrity in high-Z sources like piezoelectric sensors or pH electrodes. |
| Propagation delay (TPLH/TPHL) | 0.33 µs / 0.17 µs - suitable for sub-1 MHz window comparators and fast overvoltage latch applications. |
| Output drive (IO) | Sourcing 13 mA / sinking 14 mA - directly drives LEDs, small relays, or logic inputs without external buffers. |
| Common-mode input range | –0.1 V to 2.1 V at VDD = 3.0 V - includes ground, allowing single-supply sensing of 0 V referenced signals. |
Pinout & Package

IC Role / Device Role / Timing Role: High-gain transimpedance amplifier output fed to HA1631D02TEL-E for pulse thresholding and noise rejection. Use Value: 0.17 µs TPHL enables reliable detection of short-duration smoke events; low IDD minimizes standby power in battery-backed units. |
Use Scenario: Interfacing 4–20 mA current-loop sensors to PLC analog input cards with fault detection. IC Role / Device Role / Timing Role: One comparator validates loop integrity (open/short detection); second monitors scaled sensor voltage against alarm thresholds. Use Value: Input common-mode range including ground allows direct connection to shunt-based current sensing; 7.0 V abs-max VDD tolerance accommodates transient surges on industrial buses. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Higher supply current (500 µA typ), open-drain output, no rail-to-rail input (VCM = 0 to VDD–1.5 V). | Requires external pull-up; unsuitable for ground-referenced inputs without level shift. | Choose LM393DR only if cost is primary constraint and open-drain flexibility is needed for wired-OR bus applications. |
| TLV3702IDR | Lower supply current (800 nA typ), rail-to-rail input/output, but slower propagation (1.5 µs) and higher offset (3.5 mV max). | Optimized for nano-power systems where speed is secondary; lacks push-pull output drive strength. | Choose TLV3702IDR when ultra-low quiescent current dominates design requirements and output loading is light (e.g., MCU GPIO only). |
Compared with LM393DR and TLV3702IDR, HA1631D02TEL-E uniquely balances low power (100 µA), fast response (0.17–0.33 µs), rail-to-rail input (including ground), and robust push-pull drive (13/14 mA) - making it optimal for dual-threshold detection in space-constrained, battery-sensitive industrial and portable electronics.

FAQ
What is the maximum operating supply voltage for HA1631D02TEL-E?
The absolute maximum supply voltage for HA1631D02TEL-E is 7.0 V, as specified in the Absolute Maximum Ratings table. Continuous operation is rated from 1.8 V to 5.5 V. Exceeding 7.0 V may cause permanent damage. The HA1631D02TEL-E maintains stable performance across its full 1.8–5.5 V range, with supply current increasing predictably per Figure 2-1 and Figure 2-2 in the datasheet.
Does HA1631D02TEL-E support ground-referenced input signals?
Yes, HA1631D02TEL-E supports ground-referenced input signals: its input common-mode voltage range includes VSS (ground), with VCM specified as –0.1 V to +2.1 V at VDD = 3.0 V. This allows direct connection of sensors or dividers referenced to system ground without level-shifting circuitry - a key advantage over comparators with limited common-mode ranges like the LM393.
What output configuration does HA1631D02TEL-E use?
HA1631D02TEL-E uses a push-pull (totem-pole) output configuration on both channels. Unlike open-drain variants (e.g., HA1631D04), it does not require external pull-up resistors and delivers full-swing outputs from VSS to VDD. This enables direct driving of logic inputs, LEDs, or small loads with 13 mA source and 14 mA sink capability at VDD = 3.0 V.
How does HA1631D02TEL-E compare to HA1631D01 in terms of supply current?
HA1631D02TEL-E draws 100 µA typical supply current per comparator, whereas HA1631D01 draws only 5 µA typical. The HA1631D02TEL-E trades ultra-low quiescent current for faster propagation delay (0.17–0.33 µs vs. 0.55–1.20 µs) and higher output drive strength - making it appropriate for applications needing speed and drive capability over minimal power draw.
Is HA1631D02TEL-E available in both TSSOP-8 and MMPAK-8 packages?
No - HA1631D02TEL-E is specifically the TSSOP-8 variant, identified by package code PTSP0008JC-B and ordering suffix "TEL-E". The MMPAK-8 version carries the "MM" suffix (e.g., HA1631D02MM). Both share identical electrical specifications, but differ mechanically: TSSOP-8 has 4.4 mm × 3.0 mm body and 0.65 mm pitch, while MMPAK-8 is smaller (2.8 mm × 2.95 mm) with different thermal and mounting characteristics.
