Product details
Overview
TS3011ILT from STMicroelectronics is a 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 to 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 TS3011ILT datasheet, TS3011ILT pinout, TS3011ILT application, or TS3011ILT equivalent, key selection considerations include its micropower–speed trade-off (sub-1 mA / <10 ns), built-in 2 mV hysteresis, push-pull output drive capability (62 mA sink/source at 5 V), and AEC-Q100 qualified SOT23-5 packaging with wettable flank compatibility.
Technical Context
The TS3011ILT implements a fully differential, high-gain comparator core with internal hysteresis to suppress noise-induced output oscillation during slow or noisy input transitions. Its rail-to-rail input stage accepts common-mode voltages from (VCC−) −0.2 V to (VCC+) +0.2 V across the full operating temperature range.
Output stage uses complementary MOS push-pull architecture-eliminating external pull-up resistors-and maintains VOL ≤ 120 mV and VOH ≥ 4.84 V at 4 mA load under 5 V supply, enabling direct interfacing with CMOS logic and microcontroller GPIOs without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 8 ns typ. at 5 V - enables sampling of signals up to ~125 MHz edge rate in high-speed data acquisition. |
| Supply current | 470 μA typ. at 5 V - allows battery-powered instrumentation to achieve >1-year runtime on coin-cell sources. |
| Input hysteresis | 2 mV fixed - provides noise immunity against sub-2 mV EMI/ground bounce in automotive PCB environments. |
| Common-mode range | (VCC−) −0.2 V to (VCC+) +0.2 V - supports direct sensing of signals near supply rails, e.g., battery voltage monitoring. |
| Output drive | 62 mA source/sink at 5 V - drives 50 Ω transmission lines or multiple CMOS inputs without buffering. |
| ESD tolerance | 2 kV HBM / 200 V MM - meets IEC 61000-4-2 Level 3 for robustness in handheld test equipment. |
| Operating temp | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive applications. |
Pinout & Package
SOT23-5 package: 2.9 mm × 1.6 mm × 1.3 mm body, gull-wing leads, wettable flanks for automated optical solder-joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Digital output | CMOS-compatible push-pull node; no external pull-up required; sinks 62 mA / sources 62 mA at 5 V. |
| 2 (VCC−) | Negative supply | Reference ground for dual-supply operation; also serves as return path for single-supply configurations. |
| 3 (IN+) | Non-inverting input | Rail-to-rail capable; input bias current ≤ 20 pA enables high-impedance sensor interface (e.g., thermistor dividers). |
| 4 (IN−) | Inverting input | Matches IN+ in offset, drift, and common-mode range; supports precision threshold detection with matched trace routing. |
| 5 (VCC+) | Positive supply | Accepts 2.2–5 V; decoupling mandatory within 2 mm due to 8 ns switching sensitivity to supply noise. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Enables accurate comparison of signals spanning full supply range-critical for battery voltage monitoring down to 0 V. |
| Built-in 2 mV hysteresis | Eliminates need for external positive feedback resistors, reducing BOM count and layout area in space-constrained OBCs. |
| Push-pull output | Drives capacitive loads ≤ 20 pF directly; avoids rise-time degradation from pull-up resistor RC time constant. |
| AEC-Q100 qualified | Validated for automotive powertrain and charging systems requiring lifetime reliability at 125 °C junction temperature. |
| Wettable flank leads | Supports automated AOI inspection of solder fillets-essential for zero-defect manufacturing in EV production lines. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3501IDBVR | Higher supply current (2.3 mA typ.), faster propagation (4.5 ns), no built-in hysteresis | Requires external hysteresis network; unsuitable for low-power portable designs | Choose when absolute speed >8 ns is critical and power budget allows >2× ICC. |
| MAX961ESA+ | Wider supply range (2.7–5.5 V), higher input offset (±1.5 mV), SC70-6 package | Lacks AEC-Q100 qualification; not approved for automotive under-hood use | Prefer for industrial instrumentation where automotive qualification is unnecessary and 6-pin layout fits. |
Compared with TLV3501IDBVR and MAX961ESA+, the TS3011ILT uniquely balances ultra-low ICC (470 μA), integrated hysteresis, and AEC-Q100 compliance-making it the only drop-in solution for automotive OBCs requiring both micropower operation and functional safety–aligned robustness.

FAQ
What is the maximum recommended PCB trace length between VCC and bypass capacitors for TS3011ILT?
STMicroelectronics specifies ≤2 mm maximum distance between each VCC pin and its nearest 100 nF ceramic capacitor, with the 1 nF capacitor placed closest to the pin. Longer traces increase inductance, degrading high-frequency decoupling and causing propagation delay variation exceeding ±1 ns in 8 ns operation.
Does TS3011ILT support true dual-supply operation with VCC+ = +5 V and VCC− = −5 V?
No. The TS3011ILT is specified only for single-supply or asymmetric dual-supply operation where VCC+ − VCC− ≤ 5.5 V and both supplies remain within absolute maximum ratings. Applying −5 V to VCC− violates the −0.3 V minimum input voltage limit relative to VCC− and risks latch-up.
Can the exposed thermal pad on the DFN8 variant be left unconnected?
Yes. ST's datasheet explicitly states the exposed pad may be left floating or connected to VCC−. However, grounding it improves thermal resistance by ~30 °C/W and reduces junction temperature rise by up to 15 °C under 1 mA continuous output current-recommended for sustained 125 °C ambient operation.
Is the 2 mV hysteresis value adjustable via external components?
No. The 2 mV hysteresis is internally fixed and non-adjustable. It results from on-chip resistor trimming during final test and cannot be modified. For variable hysteresis, designers must select comparators like the LMH7322 or implement external positive feedback networks.
