Product details
Overview
TLV7022DDFR from Texas Instruments is a dual-channel, micropower, open-drain output comparator with rail-to-rail input capability, 5 µA quiescent current, 260 ns propagation delay (tPLH), and operation from 1.6 V to 6.5 V supply. It delivers precision voltage monitoring in battery-powered IR receivers and level translation circuits where low power and noise immunity are critical.
For engineers reviewing the TLV7022DDFR datasheet, TLV7022DDFR pinout, TLV7022DDFR application, or TLV7022DDFR equivalent, this page provides verified package mapping (SOT-23-8), confirmed dual-comparator architecture, open-drain output behavior, internal hysteresis (2–15 mV), and temperature-rated performance (–40°C to +125°C) - all essential for portable system design and fault-tolerant sensing.
Technical Context
The TLV7022DDFR implements two independent comparators with rail-to-rail inputs extending 100 mV beyond VCC and down to VEE, enabling robust operation under mismatched supply and signal conditions. Its open-drain outputs support flexible pull-up configurations up to 6 V, making it suitable for bipolar-to-single-ended conversion and multi-voltage domain interfacing.
Each channel features internal hysteresis (typ. 7.2 mV) and no phase reversal on overdriven inputs - critical for stable threshold detection in noisy environments. The device includes a Power-on-Reset (POR) circuit that holds outputs in high-impedance state during supply ramp-up, preventing spurious logic transitions at power-on.
Key Specifications

Use Value: Rail-to-rail inputs accept direct connection to Li-ion cell; no external biasing needed - reduces component count and PCB footprint. |
| Level Translator (Bipolar to Single-Ended) | Industrial Sensor Interface |
Use Scenario: Converting ±5 V analog sensor outputs (e.g., strain gauges) to 3.3 V logic-compatible digital flags for MCU GPIOs. IC Role / Device Role / Timing Role: TLV7022DDFR compares differential sensor output against mid-rail reference; open-drain outputs interface directly with 3.3 V pull-ups. Use Value: Input tolerance to 5.5 V allows direct connection to ±5 V sources without attenuation or clamping diodes - simplifies analog front-end design. |
Use Scenario: Detecting overtemperature or overcurrent faults in motor drives using thermistor or shunt-based analog signals. IC Role / Device Role / Timing Role: One comparator monitors temperature threshold; second monitors current threshold - both drive independent interrupt lines to safety controller. Use Value: –40°C to +125°C rating ensures reliable operation inside enclosures; 15 mV max hysteresis prevents nuisance tripping near trip points. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual open-drain comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV7235MFX/NOPB | Higher supply current (32 µA vs. 4.7 µA), faster propagation (4.5 ns), but only 2.7–5.5 V supply range. | Not suitable for 1.8 V or sub-2.7 V battery systems; better for high-speed industrial logic interfacing. | Select when nanosecond response is required and power budget permits >6× higher ICC. |
| TLV7022DBVR | Same electrical specs, but in 8-pin WSON (2 mm × 2 mm) with exposed thermal pad - lower RθJA (106.1°C/W vs. 212.5°C/W). | Better thermal performance in high-density layouts or sustained output loading; requires different solder stencil. | Prefer for space-constrained PCBs with thermal constraints; verify reflow profile compatibility with exposed pad. |
Compared with LMV7235MFX/NOPB and TLV7022DBVR, the TLV7022DDFR uniquely balances ultra-low power (4.7 µA), wide supply (1.6–6.5 V), and proven SOT-23 manufacturability - making it optimal for cost-sensitive, long-life portable designs where thermal headroom is moderate.

FAQ
What is the maximum input voltage the TLV7022DDFR can tolerate on its IN+ and IN– pins?
The TLV7022DDFR inputs are fault-tolerant up to 5.5 V, independent of VCC voltage - meaning they remain high-impedance and undamaged even when unpowered or operating at 1.6 V. This allows safe interfacing with legacy 5 V sensors or unregulated analog sources without external clamping.
Does the TLV7022DDFR require external hysteresis resistors for stable threshold detection?
No. The TLV7022DDFR integrates internal hysteresis (2–15 mV typ.), eliminating the need for external positive feedback components. This simplifies design, saves board space, and ensures consistent noise immunity across temperature and process variation - verified in TI's production testing.
Can the TLV7022DDFR operate from a 1.8 V supply while driving a 3.3 V pull-up on its open-drain outputs?
Yes. The TLV7022DDFR's open-drain outputs are rated to 6 V, so a 3.3 V pull-up is fully supported even when VCC = 1.8 V. This enables seamless level translation between low-voltage logic domains and higher-voltage peripherals - a key feature confirmed in the Absolute Maximum Ratings table.
What is the power-on behavior of the TLV7022DDFR outputs?
During power-up, the TLV7022DDFR's internal Power-on-Reset (POR) circuit holds both outputs in high-impedance state until VCC exceeds 1.6 V and stabilizes for ≥20 µs. This prevents false logic assertions in battery-powered systems - a behavior explicitly documented in Section 7.4.1 of the datasheet.
How does the TLV7022DDFR compare to the TLV7012 in terms of output structure and use cases?
The TLV7022DDFR uses open-drain outputs, while the TLV7012 uses push-pull outputs. This makes the TLV7022DDFR ideal for wired-OR bus configurations, level translation, and interfacing with higher-voltage controllers; the TLV7012 is better suited for driving LEDs or capacitive loads directly. Both share identical supply, speed, and input specs.
