Product details
Overview
TS3022IST from STMicroelectronics is a rail-to-rail input, push-pull output dual high-speed comparator optimized for automotive and industrial applications. It delivers 38 ns propagation delay at 2 V supply, draws only 73 µA quiescent current, operates from 1.8–5 V, and supports full -40 °C to +125 °C temperature range - enabling use in battery-powered signal conditioning and high-speed sampling systems.
For engineers reviewing the TS3022IST datasheet, TS3022IST pinout, TS3022IST application, or TS3022IST equivalent, key selection criteria include micropower operation under wide supply voltage, rail-to-rail input common-mode range up to VCC+0.2 V, guaranteed propagation delay across temperature, push-pull output drive capability (up to 51 mA sink/source at 5 V), and AEC-Q100 qualified MiniSO-8 packaging.
Technical Context
The TS3022IST integrates two independent comparators with matched internal architectures, each featuring rail-to-rail input stages capable of accepting signals from VCC− −0.2 V to VCC+ +0.2 V (at 25 °C) and maintaining functionality across the full −40 °C to +125 °C range. Its push-pull outputs eliminate need for external pull-up resistors and support direct interfacing with CMOS/TTL logic.
Designed for low-noise, high-speed decision-making, it achieves 38 ns typical TPLH/TPHL at 2 V with 100 mV overdrive and 50 pF load, while maintaining <6 mV input offset voltage (typ.) and 75 dB CMRR at 3.3 V - critical for precision threshold detection in telecom and instrumentation front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation delay | 38 ns typical (low-to-high, 2 V, 100 mV overdrive) - enables sampling rates >10 MHz in comparator-based ADCs or window detectors. |
| Supply voltage range | 1.8–5 V - supports direct integration into 1.8 V, 3.3 V, and 5 V systems without level-shifting. |
| Quiescent current | 73 µA typical at 2 V - allows continuous operation in always-on automotive sensors or portable instrumentation. |
| Input common-mode range | VCC− −0.2 V to VCC+ +0.2 V (25 °C); rail-to-rail at temperature extremes - accommodates full-scale analog inputs without attenuation. |
| Output type | Push-pull - drives CMOS/TTL loads directly; no external pull-up required; sinks 51 mA / sources 40 mA at 5 V. |
| Temperature range | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1, suitable for under-hood automotive and industrial control environments. |
| ESD tolerance | 5 kV HBM, 300 V MM - enhances robustness in handling and PCB assembly for high-reliability production. |
Pinout & Package
The TS3022IST is housed in a MiniSO-8 package (3.0 × 4.9 mm, 0.65 mm pitch), optimized for space-constrained automotive and portable designs. It features exposed pad for thermal enhancement and RoHS-compliant ECOPACK2 construction.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Push-pull output of Comparator 1 - actively drives high/low; compatible with 1.8–5 V logic families. |
| 2 | IN1− | Inverting input of Comparator 1 - accepts rail-to-rail common-mode voltages; high impedance (>100 MΩ). |
| 3 | IN1+ | Non-inverting input of Comparator 1 - matched to IN1− for low input offset and drift. |
| 4 | VCC− | Negative supply rail (GND) - must be connected to system ground; decoupling capacitor required adjacent to pin. |
| 5 | IN2+ | Non-inverting input of Comparator 2 - electrically isolated from Comparator 1; same rail-to-rail performance. |
| 6 | IN2− | Inverting input of Comparator 2 - low input bias current (86 nA typ.) minimizes error in high-impedance sensor interfaces. |
| 7 | OUT2 | Push-pull output of Comparator 2 - independently controlled; supports asynchronous dual-threshold detection. |
| 8 | VCC+ | Positive supply rail - accepts 1.8–5 V; requires local 100 nF + 10 nF + 1 nF decoupling per layout guidelines. |
Key Features

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 |
|---|---|---|---|
| LM393LVDSR | Open-drain output; 1.65–5.5 V supply; 100 ns propagation delay at 3.3 V. | Lacks push-pull drive; requires external pull-up; slower response limits use in >1 MSPS systems. | Select when cost sensitivity outweighs speed requirements and open-drain compatibility is needed. |
| TLV3502DBVR | Push-pull output; 2.7–5.5 V supply; 4.5 ns propagation delay; higher ICC (100 µA). | Faster but narrower supply range; not AEC-Q100 qualified; MiniSO-8 pinout incompatible. | Select for ultra-high-speed lab equipment where automotive qualification is unnecessary. |
Compared with LM393LVDSR and TLV3502DBVR, the TS3022IST uniquely balances automotive-grade reliability, micropower operation at 1.8 V, and sub-40 ns speed - making it optimal for space- and energy-constrained embedded systems requiring guaranteed performance across extreme temperatures.

FAQ
What is the maximum recommended supply voltage for TS3022IST?
The absolute maximum supply voltage is 5.5 V, but the device is specified for reliable operation from 1.8 V to 5 V. Operating above 5 V risks permanent damage and voids AEC-Q100 qualification. Electrical characteristics (e.g., propagation delay, output drive) are guaranteed only within the 1.8–5 V range per DS6029 Rev 6.
Does TS3022IST require external pull-up resistors on its outputs?
No. TS3022IST features true push-pull outputs capable of actively sourcing and sinking current - eliminating need for external pull-up resistors. This reduces BOM count, PCB area, and power loss, especially critical in battery-powered applications where every µA matters.
Can TS3022IST operate with inputs exceeding the supply rails?
No. Input voltages must remain within (VCC−) −0.3 V to (VCC+) +0.3 V per absolute maximum ratings. Exceeding this range risks latch-up or permanent damage. The rail-to-rail input stage operates *within* the supply rails - not beyond them - and supports common-mode range up to VCC+ +0.2 V at 25 °C.
Is the MiniSO-8 package of TS3022IST thermally enhanced?
Yes. The MiniSO-8 package includes an exposed thermal pad (connected internally to VCC−) that significantly improves thermal resistance (Rthjc = 39 °C/W). For optimal performance, the pad must be soldered to a dedicated copper pour on the PCB using ≥4 thermal vias to inner ground planes - per ST's layout recommendations in DS6029 Section 4.
