Product details
Overview
TLV7012DDFR from Texas Instruments is a dual-channel, micropower comparator with push-pull outputs, rail-to-rail input capability (VEE to VCC + 0.1 V), 5 µA quiescent supply current, and 260 ns typical propagation delay at 5 V. It operates from 1.6 V to 6.5 V and is used in battery-powered voltage monitoring, level translation, and threshold detection circuits.
For engineers reviewing the TLV7012DDFR datasheet, TLV7012DDFR pinout, TLV7012DDFR application, or TLV7012DDFR equivalent, key selection criteria include dual-channel push-pull output drive strength, ultra-low power consumption across wide temperature range (–40°C to 125°C), internal hysteresis for noise immunity, and compatibility with 1.8 V/3.3 V/5 V systems without external biasing.
Technical Context
The TLV7012DDFR implements two independent high-precision comparators with rail-to-rail inputs extending 100 mV beyond VCC and no phase reversal under overdrive. Each channel features internal hysteresis (2–15 mV) and a push-pull output stage capable of sourcing/sinking ≥3 mA at 5 V.
It integrates a Power-on-Reset (POR) circuit that holds outputs low during supply ramp-up until VCC ≥ 1.6 V, ensuring deterministic startup behavior. The device supports single-supply operation with VEE tied to ground and exhibits 73 dB CMRR and 77 dB PSRR at 5 V, enabling reliable operation in noisy industrial and portable environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6 V to 6.5 V - enables direct interface with 1.8 V logic, Li-ion battery systems, and legacy 5 V rails without level shifting. |
| Quiescent Supply Current | 5 µA per channel - allows continuous monitoring in always-on sensor nodes with multi-year battery life. |
| Propagation Delay | 260 ns (tPLH), 310 ns (tPHL) at 100 mV overdrive - provides fast response to fault conditions while maintaining micropower efficiency. |
| Input Offset Voltage | ±0.1 mV (typ), ±8 mV (max) - ensures accurate threshold detection down to sub-millivolt levels in precision monitoring. |
| Common-Mode Input Range | VEE to VCC + 0.1 V - supports sensing above supply rail (e.g., overvoltage detection) without external resistive dividers. |
| Output Drive Strength | Sources/sinks ≥3 mA at VOH/VOL - directly drives LEDs, logic inputs, or small capacitive loads without external buffers. |
| Operating Temperature | –40°C to +125°C - qualified for automotive cabin, industrial control, and outdoor IoT deployments. |
Pinout & Package
TLV7012DDFR is packaged in an 8-pin SOT-23 (DDF) package measuring 2.90 mm × 1.60 mm, optimized for space-constrained PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUTA (Pin 1) | Output, Channel A | Push-pull digital output - actively drives high/low; no external pull-up required for logic interfacing. |
| INA– (Pin 2) | Inverting Input, Channel A | Differential input node - accepts signals up to VCC + 0.1 V; fault-tolerant to 5.5 V regardless of VCC state. |
| INA+ (Pin 3) | Noninverting Input, Channel A | Differential input node - same fault tolerance and rail-to-rail range as INA–; defines comparison polarity. |
| VEE (Pin 4) | Negative Supply / Ground | Reference return path - tied to system ground in single-supply configurations; sets lower common-mode boundary. |
| INB+ (Pin 5) | Noninverting Input, Channel B | Independent second comparator input - enables dual-threshold or window detection without additional ICs. |
| INB– (Pin 6) | Inverting Input, Channel B | Second differential input - supports mirrored or complementary sensing topologies across both channels. |
| OUTB (Pin 7) | Output, Channel B | Independent push-pull output - synchronously or asynchronously controlled; shares no internal coupling with OUTA. |
| VCC (Pin 8) | Positive Supply | Main power rail - supplies both comparators; POR circuit activates below 1.6 V to prevent metastable outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with overrail capability | Accepts inputs up to VCC + 0.1 V - eliminates need for external attenuators when monitoring voltages exceeding supply rails. |
| Internal hysteresis | 2–15 mV programmable via supply voltage - suppresses chatter on slow-moving or noisy input signals without external feedback components. |
| No phase inversion on overdriven inputs | Maintains correct output polarity even when IN+ or IN– exceeds VCC/VEE - prevents false triggering in transient-heavy environments. |
| Power-on-reset (POR) circuit | Holds OUTA/OUTB low until VCC ≥ 1.6 V - guarantees known initial state during cold start or brownout recovery. |
| Fault-tolerant inputs | Withstand 0–5.5 V input range independent of VCC - enables "power-first" sensor connection where analog signals are present before power-up. |
Applications
| Battery Voltage Monitor | IR Receiver Front End |
|---|---|
Use Scenario: Monitoring Li-ion cell voltage during charging/discharging to trigger low-battery alerts or cutoff. IC Role / Device Role / Timing Role: Dual comparator implements undervoltage lockout (UVO) and overvoltage protection (OVP) thresholds simultaneously. Use Value: 5 µA total quiescent current extends standby time; rail-to-rail inputs directly sense 0–4.2 V cell range without scaling resistors. | Use Scenario: Converting modulated IR photodiode current into clean digital pulses for microcontroller decoding. IC Role / Device Role / Timing Role: High-speed comparator shapes analog IR envelope into TTL-compatible square waves with minimal jitter. Use Value: 260 ns propagation delay preserves modulation fidelity up to ~1 MHz; internal hysteresis rejects ambient light noise. |
| Level Translator | Window Comparator |
Use Scenario: Interfacing 1.8 V sensor outputs to 3.3 V MCU GPIO pins with precise threshold alignment. IC Role / Device Role / Timing Role: Single comparator acts as unidirectional level shifter by comparing sensor output against fixed reference. Use Value: Push-pull output drives 3.3 V logic high/low directly; 1.6 V minimum supply allows co-location with 1.8 V domain. | Use Scenario: Detecting if a sensor signal remains within safe operational bounds (e.g., temperature, pressure). IC Role / Device Role / Timing Role: Two comparators configured as upper/lower threshold detectors with shared input and OR'd outputs. Use Value: Integrated dual-channel architecture reduces board area vs. discrete solutions; matched offset minimizes window asymmetry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7022DDFR | Open-drain output instead of push-pull; identical supply range, quiescent current, and propagation delay. | Requires external pull-up for logic-high output; supports wired-OR bus architectures and level translation beyond VCC. | Select TLV7022DDFR when interfacing to mixed-voltage buses or implementing active-low interrupt lines. |
| LMV393IDR | Higher quiescent current (20 µA), slower propagation delay (300–600 ns), no internal hysteresis, wider supply range (2.7–36 V). | Less suitable for ultra-low-power battery operation; requires external hysteresis resistor network for noise immunity. | Choose LMV393IDR only when higher supply voltage tolerance or legacy pinout compatibility is mandatory. |
Compared with TLV7022DDFR, TLV7012DDFR offers immediate logic-level outputs without pull-ups but lacks bus-sharing capability; versus LMV393IDR, it delivers 4× lower power and built-in hysteresis at the cost of reduced maximum supply voltage.

FAQ
What is the maximum input voltage allowed on the TLV7012DDFR inputs?
The TLV7012DDFR inputs are fault-tolerant up to 5.5 V regardless of VCC state, and the recommended common-mode range extends from VEE to VCC + 0.1 V. This allows direct connection of sensors or signals exceeding the supply rail - for example, monitoring a 5 V bus while operating from a 3.3 V supply. Exceeding 5.5 V risks permanent damage per absolute maximum ratings.
Does the TLV7012DDFR require external hysteresis components?
No, the TLV7012DDFR includes internal hysteresis ranging from 2 mV to 15 mV depending on supply voltage and temperature. This eliminates the need for external positive-feedback resistors in most noise-prone applications like motor control feedback or environmental sensing. External hysteresis may still be added for custom thresholds, but it is not required for basic noise immunity.
Can the TLV7012DDFR operate from a single 1.8 V supply?
Yes, the TLV7012DDFR is fully specified to operate from 1.6 V to 6.5 V, including 1.8 V single-supply configurations. At 1.8 V, it maintains 5 µA quiescent current, 260 ns propagation delay, and rail-to-rail input operation from ground to 1.9 V - making it ideal for modern ultra-low-voltage microcontrollers and energy-harvesting systems.
How does the Power-on-Reset (POR) function behave in the TLV7012DDFR?
The TLV7012DDFR's POR circuit holds both OUTA and OUTB low whenever VCC is below 1.6 V. Once VCC rises above this threshold and stabilizes, the outputs begin reflecting the instantaneous differential input state. This ensures deterministic startup behavior in battery-powered systems where supply ramps slowly, preventing spurious interrupts or latch-up during power-up sequences.
What is the output drive capability of the TLV7012DDFR at 3.3 V supply?
At VCC = 3.3 V, the TLV7012DDFR push-pull outputs can source ≥2.5 mA while maintaining VOH ≥ 3.0 V, and sink ≥2.5 mA while maintaining VOL ≤ 300 mV. This is sufficient to drive standard CMOS inputs, small LEDs (with series resistor), or 10–15 pF capacitive loads directly - eliminating buffer stages in compact designs.
