Product details
Overview
HA1631D01TEL-E from Renesas is a dual CMOS comparator with push-pull full-swing outputs, designed for low-voltage single-supply operation (1.8–5.5 V), 5 µA typical supply current per comparator, 5 mV maximum input offset voltage, and rail-to-rail input common-mode range including ground. It enables direct interfacing with TTL/CMOS logic in battery-powered sensor monitoring and portable power management circuits.
For engineers reviewing the HA1631D01TEL-E datasheet, HA1631D01TEL-E pinout, HA1631D01TEL-E application, or HA1631D01TEL-E equivalent, key selection criteria include ultra-low IDD at 1.8 V, guaranteed VOH ≥ 2.9 V at VDD = 3.0 V, open-drain compatibility of related variants (HA1631D03/04), and TSSOP-8 package suitability for space-constrained PCB layouts.
Technical Context
The HA1631D01TEL-E implements two independent high-impedance CMOS comparators on a single die, each featuring picoamp-level input bias current (1 pA typ) and internal ESD protection. Its push-pull output stage delivers full-swing logic-compatible levels without external pull-ups.
It operates across –40°C to +85°C with supply rejection ratio (PSRR) of 60–80 dB and common-mode rejection ratio (CMRR) of 60–80 dB, supporting stable threshold detection in noisy industrial and portable environments where supply rails vary or share switching regulators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - Enables operation from single-cell Li-ion (3.0 V), coin cell (3.0 V), or regulated 3.3 V/5 V rails without level-shifting. |
| Supply Current (per comparator) | 5 µA typical at 25°C - Supports multi-year battery life in always-on wake-up or low-duty-cycle sensing applications. |
| Input Offset Voltage | ≤5 mV max - Ensures accurate threshold detection within ±2.5 mV over temperature and process variation. |
| Input Bias Current | 1 pA typical - Minimizes voltage error across high-impedance sensor dividers (e.g., thermistors, photodiodes). |
| Output High Voltage | ≥2.9 V at VDD = 3.0 V, RL = 10 kΩ - Guarantees TTL/74HC logic-high margin with 0.1 V noise headroom. |
| Common-Mode Input Range | Includes ground (–0.1 V to 2.1 V at VDD = 3.0 V) - Allows direct sensing of signals referenced to system ground without level shifters. |
| Propagation Delay | 1.20 µs TPLH / 0.55 µs TPHL (typ) at 100 mV overdrive - Supports response times suitable for 500 kHz window-comparator or zero-crossing detection. |
Pinout & Package
HA1631D01TEL-E is packaged in a Pb-free, RoHS-compliant TSSOP-8 (PTSP0008JC-B) with 0.65 mm pitch, 4.4 mm × 3.0 mm body, and 1.1 mm max height - optimized for automated SMT assembly and thermal performance in compact designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VSS | Ground reference for both comparators and output stage; must be connected directly to system ground plane. |
| 2 | VIN1(+) | Inverting input of Channel 1 - used for reference voltage connection in standard comparator configuration. |
| 3 | VIN1(–) | Non-inverting input of Channel 1 - accepts signal to be compared against VIN1(+). |
| 4 | VOUT1 | Push-pull output of Channel 1 - drives high/low actively; compatible with CMOS/TTL loads up to 28 mA sink/source. |
| 5 | VIN2(+) | Inverting input of Channel 2 - independent of Channel 1; supports dual-threshold or window-detection topologies. |
| 6 | VIN2(–) | Non-inverting input of Channel 2 - enables separate signal path for second comparison function. |
| 7 | VOUT2 | Push-pull output of Channel 2 - electrically isolated from VOUT1; allows independent logic-level assertion per channel. |
| 8 | VDD | Positive supply rail - powers both comparators and output drivers; decoupling capacitor (0.1 µF) required adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply current | 5 µA per comparator enables >10-year battery life in IoT endpoint sensors with 10 µA average system current. |
| Rail-to-rail input capability | Input common-mode range includes ground and extends to VDD–0.1 V - eliminates need for external bias networks in single-supply systems. |
| Full-swing push-pull output | VOH ≥ VDD–0.1 V and VOL ≤ 0.1 V at 10 kΩ load - ensures robust logic interfacing without external pull resistors. |
| High ESD immunity | On-chip ESD protection meets JEDEC JS-001 Class 2 (±2 kV HBM) - reduces board-level protection component count. |
| Low input offset drift | VIO ≤ 5 mV max over –40°C to +85°C - maintains accuracy in automotive cabin or industrial ambient temperature swings. |
Applications
| Battery Voltage Monitor | Window Comparator for Sensor Thresholds |

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 (200 µA typ), wider VDD range (2–36 V), open-drain only, no rail-to-rail input. | Requires external pull-up; unsuitable for <2 V operation or ground-referenced inputs without biasing. | Select LM393DR only when higher voltage tolerance (>5.5 V) or cost sensitivity outweighs low-power and input-range requirements. |
| TLV3702IDR | Lower supply current (1 µA typ), rail-to-rail input/output, but 5.5 V max VDD and 1.5 V min VDD - narrower low-voltage margin than HA1631D01TEL-E. | Superior low-IQ performance but lacks guaranteed 1.8 V operation; not validated for 1.8 V logic interfacing. | Choose TLV3702IDR for ultra-low-power designs operating strictly ≥2.0 V; verify 1.8 V functionality separately if required. |
Compared with LM393DR and TLV3702IDR, HA1631D01TEL-E uniquely guarantees 1.8 V operation with rail-to-rail inputs and 5 µA supply current - making it optimal for energy-harvesting and coin-cell-powered systems where supply headroom and input flexibility are critical.

FAQ
What is the minimum operating voltage for HA1631D01TEL-E?
The HA1631D01TEL-E is fully specified down to 1.8 V, with guaranteed performance including 5 µA typical supply current, 5 mV max input offset voltage, and functional push-pull outputs. Operation below 1.8 V is not characterized and may result in undefined behavior or failure to meet datasheet limits.
Does HA1631D01TEL-E support rail-to-rail input common-mode range?
Yes, HA1631D01TEL-E supports an input common-mode voltage range from –0.1 V to 2.1 V at VDD = 3.0 V, which includes ground and extends close to VDD. This allows direct connection of ground-referenced signals such as thermistor bridges or AC-coupled waveforms without external biasing networks.
Can HA1631D01TEL-E drive standard CMOS logic directly?
Yes, HA1631D01TEL-E's push-pull outputs deliver VOH ≥ 2.9 V and VOL ≤ 0.1 V at VDD = 3.0 V with 10 kΩ load, meeting 3.3 V CMOS logic-high (≥2.4 V) and logic-low (≤0.4 V) thresholds. No external pull-up resistors are needed, simplifying interface design.
Is HA1631D01TEL-E pin-compatible with HA1631D03TEL-E or HA1631D04TEL-E?
No - while HA1631D01TEL-E (push-pull) and HA1631D03/04TEL-E (open-drain) share identical pinout and package, their output stages differ fundamentally. Substituting HA1631D01TEL-E for an open-drain variant requires removing external pull-up resistors and verifying logic-level compatibility with downstream loads.
What is the maximum capacitive load HA1631D01TEL-E can drive reliably?
HA1631D01TEL-E is characterized up to 15 pF load capacitance in the datasheet (response time test condition). Driving >15 pF may increase propagation delay and cause ringing; for loads >30 pF, add a series resistor (10–100 Ω) near the output to dampen overshoot and maintain stability.
