Product details
Overview
TS3011ICT from STMicroelectronics is a single rail-to-rail input, push-pull output high-speed comparator optimized for automotive and industrial signal conditioning. It delivers 8 ns propagation delay at 5 V, consumes only 470 μA typical supply current, operates from 2.2–5 V, and supports –40 °C to +125 °C ambient temperature-enabling use in on-board chargers and portable telecom systems.
For engineers reviewing the TS3011ICT datasheet, TS3011ICT pinout, TS3011ICT application, or TS3011ICT equivalent, key selection criteria include propagation delay vs. supply voltage, rail-to-rail input common-mode range (VCC− −0.2 V to VCC+ +0.2 V), push-pull output drive capability (62 mA sink/source at 5 V), and AEC-Q100 qualification for automotive deployment.
Technical Context
The TS3011ICT implements a high-gain, low-offset comparator core with built-in 2 mV hysteresis to suppress noise-induced oscillation during slow or noisy input transitions. Its rail-to-rail input stage accepts signals from VCC− −0.2 V to VCC+ +0.2 V across the full operating temperature range, enabling direct interfacing with sensors and ADC references without level-shifting.
Push-pull CMOS output drives loads up to 4 mA with VOH = 4.84 V (min) and VOL = 90 mV (max) at 5 V supply and 25 °C, eliminating external pull-up resistors. The device achieves stable operation under fast overdrive conditions (5–50 mV), with propagation delay variation <3 ns across VCC = 2.2–5 V and temperature = –40 to +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 8 ns typ. at 5 V, 50 mV overdrive - enables sampling of >100 MHz analog edge transitions in high-speed data acquisition. |
| Supply current | 470 μA typ. at 5 V - supports battery-powered instrumentation with multi-year runtime on coin-cell sources. |
| Rail-to-rail input range | VCC− −0.2 V to VCC+ +0.2 V - allows direct connection to 0–5 V sensor outputs or DACs without external biasing. |
| Output type | Push-pull CMOS - eliminates need for external pull-up, reduces board space, and ensures fast rise/fall times (TR = 1.1 ns, TF = 1.0 ns). |
| Operating temperature | –40 °C to +125 °C - qualified per AEC-Q100 Grade 1, suitable for under-hood automotive electronics and industrial motor drives. |
| Input hysteresis | 2 mV built-in - prevents chatter on slowly varying or noisy inputs (e.g., thermistor-based temperature monitoring). |
| ESD tolerance | 2 kV HBM / 200 V MM - meets IEC 61000-4-2 system-level ESD robustness requirements for front-end signal paths. |
Pinout & Package
TS3011ICT is supplied in SC70-5 package (2.0 × 2.1 mm, 0.65 mm pitch), featuring wettable flanks for automated optical solder-joint inspection. Pin numbering follows JEDEC MO-203AA standard with top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | CMOS push-pull output - actively drives high/low; compatible with 1.8–5 V logic families and capable of sourcing/sinking ≥60 mA. |
| 2 | VCC− | Negative supply reference - must be connected to system ground or negative rail; serves as common return for inputs and output. |
| 3 | IN+ | Non-inverting input - accepts rail-to-rail voltages; differential input impedance >1012 Ω minimizes loading on precision sensor sources. |
| 4 | IN− | Inverting input - matched to IN+ in offset and bias current (IIB = 1–20 pA); enables precise threshold detection with low drift. |
| 5 | VCC+ | Positive supply input - supports 2.2–5 V operation; internal regulation ensures stable internal biasing across supply range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Enables direct interface with 0–5 V analog sources (e.g., battery voltage monitors, current-sense amplifiers) without external level shifters. |
| 8 ns propagation delay | Supports real-time response in high-speed sampling systems where comparator latency directly impacts effective sampling rate. |
| 470 μA supply current at 5 V | Reduces thermal load in dense PCB layouts and extends battery life in portable communication devices (e.g., handheld test equipment). |
| AEC-Q100 qualified | Validated for automotive applications including on-board chargers and battery management systems requiring Grade 1 temperature reliability. |
| 2 mV built-in hysteresis | Eliminates need for external positive feedback resistors, simplifying layout and improving consistency across production units. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3501DBVR | Higher supply current (2.3 mA typ.), faster propagation (4.5 ns), no built-in hysteresis, wider supply range (2.7–5.5 V) | Requires external hysteresis network; better suited for ultra-high-speed oscilloscope trigger circuits than noisy automotive environments | Select when nanosecond-level speed outweighs power and integration needs; verify hysteresis design for EMI immunity. |
| MAX961ESA+ | Lower supply current (120 μA typ.), slower propagation (4.5 ns typ. at 3.3 V), rail-to-rail output only, not rail-to-rail input | Limited input range (VSS +0.2 V to VDD −0.2 V) requires level-shifting for 0 V referenced sensors | Prefer for ultra-low-power battery monitoring where input range flexibility is secondary to quiescent current. |
Compared with TLV3501DBVR and MAX961ESA+, TS3011ICT uniquely balances 8 ns speed, 470 μA consumption, rail-to-rail inputs, built-in hysteresis, and AEC-Q100 qualification-making it optimal for automotive signal conditioning where integration, robustness, and thermal reliability are co-prioritized.

FAQ
What is the maximum recommended supply voltage for TS3011ICT?
The absolute maximum supply voltage (VCC) is 5.5 V, but the device is specified for reliable operation between 2.2 V and 5.0 V. Operating above 5.0 V risks exceeding internal junction temperature limits and invalidating AEC-Q100 qualification-designs should maintain VCC ≤ 5.0 V with ±5% tolerance for production margin.
Does TS3011ICT require external hysteresis for noise immunity?
No-TS3011ICT integrates 2 mV of internal hysteresis, eliminating the need for external positive feedback resistors. This simplifies PCB layout, improves unit-to-unit consistency, and maintains noise immunity across temperature (–40 °C to +125 °C) without recalibration.
Can TS3011ICT drive a 50 Ω transmission line directly?
No-its push-pull output is rated for 4 mA load (VOH/VOL specified at Isource/Isink = 4 mA), insufficient for 50 Ω termination at 5 V (requiring 100 mA). Use a dedicated line driver (e.g., SN65LVDS1) or series-terminate with 49.9 Ω resistor for point-to-point LVDS-compatible signaling.
Is the exposed pad on the DFN8 package required to be grounded?
No-the DFN8 variant's exposed pad may be left floating or connected to VCC− (ground) per layout preference. When grounded, it improves thermal dissipation (RθJA = 57 °C/W); when floating, it retains full functionality but increases junction temperature by ~15 °C at 1 mA load under worst-case ambient.
