Product details
Overview
TS3022IDT 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 telecom receivers and engine control signal conditioning circuits.
For engineers reviewing the TS3022IDT datasheet, TS3022IDT pinout, TS3022IDT application, or TS3022IDT equivalent, key selection criteria include micropower consumption under 100 µA, guaranteed high-speed response across 1.8–5 V supply, rail-to-rail input common-mode range, push-pull output drive capability, and AEC-Q100 qualified SO-8 packaging for automotive-grade reliability.
Technical Context
The TS3022IDT integrates two independent comparators with complementary CMOS input stages enabling rail-to-rail input voltage operation down to 1.8 V. Its propagation delay remains stable across supply voltages (38–42 ns typ. at 2–5 V) and temperature (-40 °C to +125 °C), with input offset voltage drift limited to 3–20 µV/°C.
Each comparator features push-pull outputs capable of sourcing up to 51 mA and sinking up to 40 mA at 5 V, eliminating external pull-up resistors. ESD robustness (5 kV HBM, 300 V MM) and latch-up immunity (200 mA) are validated per JEDEC standards, supporting deployment in noisy automotive and industrial environments.
Key Specifications

| 4 (VCC−) | Negative supply rail | Ground reference for dual-supply operation or 0 V return in single-supply configurations |
| 5 (VCC+) | Positive supply rail | Accepts 1.8–5 V; decoupling capacitor must be placed within 2 mm for stable high-speed operation |
| 6 (IN−B) | Inverting input of comparator B | Independent channel with identical rail-to-rail input performance and offset characteristics as Channel A |
| 7 (IN+B) | Non-inverting input of comparator B | Enables dual-threshold detection or window comparator configuration with external resistors |
| 8 (OUTB) | Push-pull output of comparator B | Electrically isolated from OUTA; supports asynchronous event detection on separate signal paths |

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 output, 1.5 µs propagation delay, 200 µA ICC, no rail-to-rail input | Requires external pull-up; unsuitable for >100 kHz signal conditioning or low-voltage (1.8 V) operation | Select only for cost-sensitive, non-timing-critical DC threshold detection at 5 V |
| TLV3502IDR | 3.5 ns propagation delay, 85 µA ICC, rail-to-rail input, but rated only to 85 °C ambient | Lacks automotive temperature qualification; not validated for sustained 125 °C junction operation | Prefer for portable instrumentation where speed outweighs temperature grade requirements |
Compared with LM393DR and TLV3502IDR, TS3022IDT uniquely balances sub-40 ns speed, micropower operation, rail-to-rail input, and full AEC-Q100 Grade 1 qualification - making it the only option for automotive high-speed analog front-ends requiring both precision timing and extended temperature resilience.

FAQ
What is the maximum recommended supply voltage for TS3022IDT?
The absolute maximum supply voltage is 5.5 V, but the device is specified for reliable operation up to 5 V. Operation above 5 V risks exceeding absolute maximum ratings and may cause permanent damage or parametric shift. Electrical characteristics in Tables 3–5 are guaranteed only between 1.8 V and 5 V.
Does TS3022IDT require external pull-up resistors on its outputs?
No. TS3022IDT features true push-pull outputs capable of sourcing up to 51 mA and sinking up to 40 mA at 5 V. This eliminates the need for external pull-up resistors, simplifying PCB layout and reducing power loss in active-high logic interfaces.
Can TS3022IDT operate with a 1.8 V supply and still meet its 38 ns propagation delay specification?
Yes. At VCC = 1.8 V, TPLH/TPHL is 38 ns typical (Table 3, DS6029 Rev 6, p.3), confirmed across -40 °C to +125 °C. Performance remains stable due to optimized CMOS input stage and low-threshold output drivers designed for low-voltage operation.
Is the TS3022IDT pinout compatible with other dual comparators in SO-8 packages?
No. TS3022IDT uses a proprietary pin assignment: IN−A/IN+A/OUTA/VCC−/VCC+/IN−B/IN+B/OUTB. It is not pin-compatible with LM393, TLC372, or TLV3502 - each requires unique PCB layout and cannot be substituted without redesign.
