Product details
Overview
TS3022ID from STMicroelectronics is a rail-to-rail input, push-pull output dual comparator optimized for high-speed operation (38 ns propagation delay at 2 V supply) and ultra-low power consumption (73 μA per comparator). It operates from 1.8 V to 5 V over -40°C to +125°C and is packaged in SO-8. It serves as a precision threshold detector in portable communication systems requiring fast response with micropower efficiency.
For engineers reviewing the TS3022ID datasheet, TS3022ID pinout, TS3022ID application, or TS3022ID equivalent, key selection criteria include propagation delay vs. supply voltage, rail-to-rail input common-mode range, push-pull output drive capability, and guaranteed performance across automotive-grade temperature extremes.
Technical Context
The TS3022ID integrates two independent high-speed comparators with rail-to-rail input stages enabling full-supply-range signal detection, and push-pull CMOS outputs eliminating external pull-up resistors. Its internal architecture supports stable operation down to 1.8 V while maintaining sub-50 ns propagation delay under 100 mV overdrive.
It features robust ESD tolerance (5 kV HBM), latch-up immunity (200 mA), and guaranteed electrical performance across -40°C to +125°C - validated via correlation and simulation per ST's qualification methodology. Input offset voltage remains ≤7 mV over temperature, and supply current stays below 125 μA/comp across full voltage and temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 38 ns typical (low-to-high) at VCC = 2 V, 100 mV overdrive - enables sampling rates up to ~10 MHz in comparator-based ADC front-ends. |
| Supply current / comparator | 73 μA typical at VCC = 2 V, output high - allows battery-powered designs to sustain >1-year operation on coin cells. |
| Rail-to-rail inputs | Common-mode range extends from (VCC−) −0.2 V to (VCC+) +0.2 V - supports direct interfacing with sensors and DACs operating at supply rails. |
| Push-pull outputs | Source/sink capability up to 9–51 mA depending on VCC - drives logic inputs directly without external pull-ups or level shifters. |
| Operating temperature | -40°C to +125°C - qualified for under-hood automotive, industrial motor control, and telecom base station applications. |
| Input offset voltage | ≤7 mV max over full temperature range - ensures reliable detection of small-signal thresholds (e.g., ±10 mV window comparators). |
| ESD tolerance | 5 kV HBM - protects against handling-induced transients during PCB assembly and field service. |
Pinout & Package
TS3022ID is supplied in an SO-8 package (ECOPACK® compliant, RoHS-compliant), with standard 1.27 mm pitch and 4.90 mm × 6.00 mm body dimensions. Pin numbering follows JEDEC MS-012AC.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Push-pull output of comparator A - sinks or sources current; compatible with TTL/CMOS logic inputs. |
| 2 | IN− A | Inverting input of comparator A - rail-to-rail capable; accepts signals from 0 V to VCC. |
| 3 | IN+ A | Non-inverting input of comparator A - rail-to-rail capable; used for reference or signal input. |
| 4 | VCC− | Negative supply terminal (GND when single-supply used) - must be connected to system ground plane. |
| 5 | IN+ B | Non-inverting input of comparator B - independently configurable; supports dual-threshold or window detection. |
| 6 | IN− B | Inverting input of comparator B - rail-to-rail capable; differential pair with IN+ B. |
| 7 | OUT B | Push-pull output of comparator B - electrically isolated from OUT A; enables asynchronous event detection. |
| 8 | VCC+ | Positive supply terminal - accepts 1.8 V to 5 V; decoupling capacitor (100 nF) required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Enables accurate comparison of signals near supply rails - critical for low-voltage sensor interfaces (e.g., 1.8 V ADC references). |
| 38 ns propagation delay @ 2 V | Supports real-time overvoltage/undervoltage monitoring in DC-DC converters with <100 ns fault response windows. |
| 73 μA/comparator supply current | Reduces quiescent power in always-on monitoring circuits - e.g., battery fuel gauges or wake-on-event systems. |
| Push-pull CMOS outputs | Eliminates need for external pull-up resistors - simplifies PCB layout and reduces BOM count in space-constrained modules. |
| -40°C to +125°C operation | Validated for engine control units and industrial PLC I/O modules where ambient thermal stress exceeds commercial grade limits. |
Applications
| Telecommunications Signal Detection | Portable Communication Systems |
|---|---|
|
Use Scenario: Detecting line signal presence and loss in DSL or optical transceiver front-ends. IC Role / Device Role / Timing Role: Dual comparator monitors differential receive path and reference voltage to assert LOS (Loss of Signal) flag. Use Value: 38 ns delay ensures sub-bit-period response; rail-to-rail inputs accommodate varying amplitude levels across link margins. |
Use Scenario: Battery voltage monitoring and low-power mode activation in smartphones and wearables. IC Role / Device Role / Timing Role: Comparator A detects battery undervoltage (e.g., <3.2 V); Comparator B triggers charger enable at >4.1 V. Use Value: 73 μA total quiescent current extends standby time; push-pull outputs interface directly with PMIC enable pins. |
| High-Speed Sampling Systems | Instrumentation Threshold Monitoring |
|
Use Scenario: Window comparator in oscilloscope trigger circuitry detecting signal excursions beyond user-defined bounds. IC Role / Device Role / Timing Role: Two comparators form upper/lower thresholds; outputs feed SR latch for edge-triggered capture. Use Value: Matched propagation delays (<5 ns skew between A/B) ensure precise timing alignment; 1.8 V operation supports low-voltage FPGA I/O domains. |
Use Scenario: Overtemperature warning in medical diagnostic equipment using thermistor-based voltage dividers. IC Role / Device Role / Timing Role: Compares thermistor divider output against precision reference to assert alarm before thermal shutdown. Use Value: ≤7 mV input offset minimizes calibration drift; -40°C to +125°C rating covers full clinical operating envelope. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Open-collector outputs, 1.5 V minimum supply, 1.3 μs propagation delay - lacks rail-to-rail inputs and speed. | Suitable only for non-critical, low-speed level translation; cannot replace TS3022ID in 1.8 V or high-speed designs. | Select only if cost is primary constraint and 38 ns timing is unnecessary. |
| TLV3502IDR | 3.5 ns propagation delay, 60 μA/comparator, rail-to-rail inputs - higher speed but narrower temp range (-40°C to +125°C not guaranteed). | Valid for consumer-grade portable devices but not automotive or industrial environments requiring full-temp validation. | Choose when sub-10 ns response is mandatory and extended temperature compliance is not required. |
Compared with LM393DR and TLV3502IDR, the TS3022ID uniquely balances micropower operation (73 μA), 38 ns speed, rail-to-rail inputs, and full -40°C to +125°C qualification - making it optimal for battery-constrained, thermally harsh, and timing-sensitive embedded systems.

FAQ
What is the minimum supply voltage for guaranteed operation of TS3022ID?
The TS3022ID is fully specified from 1.8 V to 5 V. At 1.8 V, propagation delay is 38 ns (typical), supply current is 73 μA/comp, and rail-to-rail input operation is maintained. Operation below 1.8 V is not characterized or guaranteed per datasheet Table 2.
Can TS3022ID drive a 10 kΩ load directly?
Yes. With VOH ≥1.88 V and VOL ≤100 mV at ISource/ISink = 1 mA (VCC = 2 V), the TS3022ID can drive a 10 kΩ load with <0.1% error - verified by Figures 5–10 showing output voltage stability across temperature and current.
Does TS3022ID require external hysteresis for noise immunity?
No external hysteresis is required for basic operation, but the device does not integrate internal hysteresis. For noisy input environments, external positive feedback (e.g., 10 MΩ resistor from OUT to IN+) adds ~5 mV hysteresis - confirmed by application note AN2712.
Is the SO-8 package of TS3022ID lead-free and RoHS-compliant?
Yes. The TS3022ID SO-8 package is ECOPACK® certified, lead-free, and fully RoHS-compliant per EU Directive 2011/65/EU, with matte tin plating and halogen-free molding compound - documented in Section 3 of the datasheet.
