Product details
Overview
TS339CN from STMicroelectronics is a micropower quad CMOS voltage comparator with 9 μA typical supply current per comparator, 2.7–16 V single-supply operation, and rail-to-rail input common-mode range including ground. It features 1 pA typical input bias current, 1.5 μs typical response time at 5 mV overdrive, and pin-to-pin compatibility with LM339 for low-power industrial sensing and battery-powered monitoring systems.
For engineers reviewing the TS339CN datasheet, TS339CN pinout, TS339CN application, or TS339CN equivalent, key selection criteria include ultra-low quiescent current, ground-sensing capability, output stage compatibility with TTL/CMOS loads, and DIP14 package suitability for prototyping and legacy board designs.
Technical Context
The TS339CN implements four independent CMOS comparators in a single monolithic IC, each with high-impedance (10¹² Ω typ.) inputs and open-drain NMOS outputs. Its input stage supports common-mode voltages from GND to VCC−1.2 V, enabling direct interface with sensors referenced to system ground.
Designed as a low-power replacement for bipolar LM339, it maintains comparable propagation delay (1.5 μs low-to-high, 2.5 μs high-to-low at 5 mV overdrive) while reducing supply current by 20×. Output logic states are defined by external pull-up configuration, supporting flexible interfacing with microcontrollers and logic families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply current | 9 μA typ. per comparator - enables multi-comparator operation in battery-powered devices with >10-year shelf life |
| Input bias current | 1 pA typ. - minimizes loading error on high-impedance sensor sources (e.g., photodiodes, thermistors) |
| Input offset voltage | 5 mV max. - ensures reliable detection of small differential signals above ~10 mV threshold |
| Response time | 1.5 μs typ. (low-to-high), 2.5 μs typ. (high-to-low) at 5 mV overdrive - suitable for slow-varying analog monitoring, not high-speed signal discrimination |
| Common-mode range | 0 V to VCC−1.2 V - allows direct comparison of signals referenced to ground without level-shifting circuitry |
| Output type | Open-drain NMOS - requires external pull-up; compatible with mixed-voltage logic interfaces and wired-OR configurations |
| ESD rating | HBM: 50 V - indicates limited robustness; requires handling precautions in uncontrolled environments |
Pinout & Package
DIP14 plastic dual-in-line package (14-pin through-hole), 20.0 mm × 8.5 mm body, 2.54 mm lead pitch, ECOPACK® compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input of comparator A | Accepts reference or feedback signal; high-impedance node requiring guarded routing |
| 2 | Non-inverting input of comparator A | Accepts sensed signal; common-mode range includes GND for direct sensor connection |
| 3 | Output of comparator A | Open-drain NMOS; must be pulled up externally to define logic HIGH level |
| 4 | GND | Power and signal reference plane; decoupling capacitor required near pin |
| 5 | Inverting input of comparator B | Independent high-Z input; electrically isolated from other comparator inputs |
| 6 | Non-inverting input of comparator B | Supports same common-mode range as pin 2; no internal level shifting |
| 7 | Output of comparator B | Open-drain output; may share pull-up with other outputs for wired-OR logic |
| 8 | VCC | Positive supply rail; bypass capacitor mandatory for stable operation |
| 9 | Inverting input of comparator C | Third independent comparator input; identical electrical characteristics to pins 1 and 5 |
| 10 | Non-inverting input of comparator C | Matches pin 2/6 performance; supports GND-referenced signal conditioning |
| 11 | Output of comparator C | Open-drain output; compatible with 3.3 V or 5 V logic pull-up targets |
| 12 | Inverting input of comparator D | Fourth comparator input; fully isolated; no crosstalk specified in datasheet |
| 13 | Non-inverting input of comparator D | Same input specs as other non-inverting inputs; usable down to 0 V |
| 14 | Output of comparator D | Final open-drain output; supports independent or shared pull-up configuration |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply current | 9 μA/comparator enables 4-channel monitoring in energy-harvesting or coin-cell applications |
| Ground-sensing input stage | Input common-mode range includes 0 V - eliminates need for negative supply or level shifters in single-supply systems |
| High input impedance | 10¹² Ω typical - preserves signal integrity from megohm-range resistive dividers and capacitive sensors |
| LM339 pin compatibility | Direct drop-in replacement in existing DIP14 footprints - reduces redesign effort for power-sensitive upgrades |
| Wide supply range | 2.7 V to 16 V single supply - supports operation across Li-ion, 5 V, and 12 V industrial rails without regulation |
Applications
| Battery Voltage Monitor | Threshold Detector for Industrial Sensors |
|---|---|
Use Scenario: Monitoring charge state of 3.7 V Li-ion or 9 V alkaline batteries in portable instruments. IC Role / Device Role / Timing Role: Quad comparator independently checks under-voltage, over-voltage, charging complete, and fault thresholds. Use Value: 9 μA total quiescent current extends battery life beyond 5 years in standby mode. | Use Scenario: Detecting temperature, pressure, or light thresholds in PLC I/O modules using RTDs or photoresistors. IC Role / Device Role / Timing Role: Compares conditioned sensor output against precision references to generate digital alarm flags. Use Value: 1 pA input bias avoids measurement error in high-impedance Wheatstone bridge arms. |
| Power Supply Sequencing Controller | Window Comparator for Analog Signal Integrity |
Use Scenario: Enforcing safe startup order of multiple DC rails (e.g., 1.2 V, 3.3 V, 5 V) in FPGA-based systems. IC Role / Device Role / Timing Role: Each comparator validates one rail's presence before enabling next-stage regulators via open-drain outputs. Use Value: Open-drain outputs allow wired-OR combination into a single enable chain without logic gates. | Use Scenario: Validating that analog sensor output remains within acceptable bounds (e.g., 0.5–4.5 V) before ADC sampling. IC Role / Device Role / Timing Role: Two comparators form upper/lower limits; third combines outputs via external diode-OR for window violation flag. Use Value: Rail-to-rail input range allows direct connection to unbuffered sensor outputs without op-amp level shifting. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339N | Higher supply current (500 μA typ.), bipolar input stage, no ground-sensing capability (VICM = VCC−1.5 V min.) | Requires higher power budget; unsuitable for GND-referenced inputs without level shifters | Select when legacy design uses LM339 footprint and power efficiency is secondary to cost |
| TS3704CD | Push-pull CMOS output (no external pull-up needed), same 9 μA supply current, identical input specs | Eliminates external resistors but lacks wired-OR capability; incompatible pinout | Select when board space is constrained and discrete pull-ups are undesirable |
Compared with LM339N and TS3704CD, TS339CN uniquely balances ultra-low power, ground-sensing inputs, and LM339-compatible pinout-making it optimal for upgrading existing DIP14 designs where power and input range are critical.

FAQ
Can TS339CN operate from a 2.7 V supply?
Yes. The TS339CN is fully specified from 2.7 V to 16 V single supply. At 2.7 V, input offset voltage remains ≤6.5 mV, supply current is ≤25 μA per comparator, and output low voltage stays below 800 mV at 6 mA sink current - meeting functional requirements for low-voltage battery monitoring.
Does TS339CN require external pull-up resistors on its outputs?
Yes. All four outputs are open-drain NMOS structures and must be pulled up to a valid logic HIGH voltage (e.g., 3.3 V or 5 V) via external resistors. Typical values range from 4.7 kΩ to 10 kΩ depending on rise time and bus capacitance requirements.
Is TS339CN suitable for automotive applications?
No. TS339CN is rated for 0 °C to +70 °C ambient operation and is not qualified to AEC-Q100 standards. For automotive use, ST offers the TS339IN variant (-40 °C to +125 °C) in DIP14 and SO14 packages with extended temperature validation.
How does TS339CN differ from TS3704 in output architecture?
TS339CN uses open-drain outputs requiring external pull-ups, enabling wired-OR logic and mixed-voltage interfacing. TS3704 features push-pull CMOS outputs that drive both HIGH and LOW actively - eliminating pull-ups but preventing wired-OR and limiting voltage domain flexibility.
