Product details
Overview
TS339ID from STMicroelectronics is a micropower quad CMOS voltage comparator with 9 μA typical supply current per comparator, 2.7–16 V single-supply operation, 1 pA typical input bias current, and rail-to-rail input common-mode range including ground-used in battery-powered sensor monitoring and low-power threshold detection circuits.
For engineers reviewing the TS339ID datasheet, TS339ID pinout, TS339ID application, or TS339ID equivalent, key selection criteria include ultra-low quiescent current, ground-sensing capability, fast 1.5 μs response at 5 mV overdrive, and SO14 package compatibility with legacy LM339 layouts.
Technical Context
The TS339ID implements four independent CMOS comparators with open-drain outputs, each featuring high-impedance (10¹² Ω typ.) inputs and internal ESD protection rated to 50 V HBM. Its input stage accepts common-mode voltages from GND to VCC−1.2 V, enabling direct interfacing with sensors referenced to system ground.
It operates across industrial temperature range (−40 °C to +125 °C) and supports both single-supply (2.7–16 V) and dual-supply (±1.35 V to ±8 V) configurations. Output logic states are determined by differential input voltage exceeding 5 mV, with propagation delay tightly specified at 1.5 μs (tPLH) and 2.5 μs (tPHL) under standard test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply current | 9 μA typ./comparator - enables multi-year operation on coin-cell batteries in always-on sensing nodes |
| Input bias current | 1 pA typ. - preserves signal integrity in high-impedance sensor interfaces (e.g., pH electrodes, photodiodes) |
| Input common-mode range | 0 V to VCC−1.2 V - allows direct GND-referenced input without level-shifting circuitry |
| Response time | 1.5 μs low-to-high (5 mV overdrive) - supports real-time fault detection in power supply supervisors |
| Output type | Open-drain - permits wired-OR configuration and flexible pull-up voltage selection (up to 18 V) |
| Input offset voltage | 6.5 mV max - sets minimum detectable voltage difference in precision threshold applications |
| ESD rating | 50 V HBM - meets basic handling robustness for non-automotive industrial assembly environments |
Pinout & Package
TS339ID is supplied in a 14-lead SOIC (SO14) package, 8.75 mm × 5.8 mm body size, 1.27 mm lead pitch, with gull-wing leads and RoHS-compliant ECOPACK® construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | Inverting input (−) | Accepts reference or feedback signal; high-impedance node requiring guarded routing |
| 3, 4, 7, 8 | Non-inverting input (+) | Receives sensed signal; common-mode range includes GND for direct sensor connection |
| 9, 10, 13, 14 | Output | Open-drain NMOS output; requires external pull-up to define logic HIGH voltage level |
| 11 | VCC | Positive supply terminal; supports 2.7–16 V single supply or +VCC in dual-supply mode |
| 12 | GND | Ground reference for all inputs, outputs, and internal circuitry; must be low-impedance |
Key Features
| Feature | Design Value |
|---|---|
| Micropower operation | 9 μA/comparator enables >10-year battery life in wireless sensor nodes powered by CR2032 cells |
| Ground-sensing input | Input common-mode range includes 0 V - eliminates need for negative supply or level shifters in single-supply systems |
| CMOS input stage | 10¹² Ω input impedance minimizes loading on high-Z sources like thermistors and capacitive sensors |
| LM339 pin compatibility | Pin-to-pin and functionally compatible with bipolar LM339 - allows drop-in upgrade to lower power without PCB redesign |
| Wide supply range | Operates from 2.7 V (Li-ion cutoff) to 16 V (industrial 12 V rails) - supports diverse power domains |
Applications
| Battery Voltage Monitor | Over-Temperature Protection |
|---|---|
Use Scenario: Monitoring Li-ion cell voltage during discharge to trigger shutdown before deep discharge. IC Role / Device Role / Timing Role: Quad comparator compares cell voltage against four precision thresholds (e.g., 3.6 V, 3.4 V, 3.2 V, 3.0 V) using resistor-divider references. Use Value: 9 μA total quiescent current extends battery runtime by >20% versus LM339-based designs. | Use Scenario: Detecting thermal runaway in motor drives using NTC thermistor network. IC Role / Device Role / Timing Role: One comparator channel monitors thermistor voltage divider; remaining channels reserved for auxiliary fault signals. Use Value: 1 pA input bias avoids self-heating error in high-resistance NTC circuits (>100 kΩ). |
| Smoke Detector Sensing | Industrial PLC Input Conditioning |
Use Scenario: Interpreting ionization chamber current pulses in residential smoke alarms. IC Role / Device Role / Timing Role: High-gain comparator amplifies and digitizes weak, transient currents (<100 nA) from chamber electrodes. Use Value: 1.5 μs response ensures reliable pulse capture at 10 kHz modulation frequencies. | Use Scenario: Converting 4–20 mA loop signals to digital logic levels in DIN-rail mounted controllers. IC Role / Device Role / Timing Role: Comparator thresholds set at 3.6 mA (fault), 4 mA (low), 20 mA (high), and 22 mA (overrange) for status encoding. Use Value: Open-drain outputs interface directly with optocouplers and 24 V PLC backplanes without level translators. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | 20× higher supply current (180 μA/comparator); bipolar input; no GND-sensing capability | Requires level-shifting for GND-referenced inputs; unsuitable for <5-year battery life targets | Select when legacy footprint reuse is critical and power budget >100 μA is acceptable |
| TS3704CDT | Push-pull CMOS output (no external pull-up needed); identical supply current and input specs | Eliminates pull-up resistors but lacks wired-OR flexibility; not pin-compatible | Select when board space is constrained and output load drives CMOS logic directly |
Compared with LM339DR and TS3704CDT, TS339ID uniquely balances ultra-low power, ground-sensing inputs, and LM339 pin compatibility-making it optimal for retrofitting existing designs with extended battery life without layout changes.

FAQ
Can TS339ID operate from a 2.7 V single supply?
Yes. TS339ID is fully specified from 2.7 V to 16 V single supply, with guaranteed performance including 1.5 μs response time and 6.5 mV input offset voltage at VCC = 2.7 V and TA = 25 °C. Input common-mode range extends down to 0 V, supporting direct interfacing with low-voltage sensors.
What is the maximum sink current capability of the TS339ID output?
The TS339ID output can sink up to 20 mA continuously, with absolute maximum rating of 20 mA per channel. At IOL = 6 mA, the low-level output voltage is 400–550 mV (typ./max) at VCC = 3 V, confirming robust drive strength into standard TTL or CMOS loads with appropriate pull-up.
Does TS339ID require external pull-up resistors on its outputs?
Yes. TS339ID features open-drain NMOS outputs and requires external pull-up resistors to define the logic HIGH voltage level. Pull-up values typically range from 10 kΩ (for speed-critical applications) to 100 kΩ (for ultra-low-power use), with voltage up to 18 V permitted per absolute maximum ratings.
How does TS339ID differ from TS3704 in practical design?
TS339ID uses open-drain outputs and matches LM339 pinout, while TS3704 offers push-pull outputs and different pin mapping. Both share 9 μA supply current and 1 pA input bias, but TS3704 eliminates pull-up resistors at the cost of losing wired-OR capability-making TS339ID preferable for fault-bus architectures and legacy upgrades.
