Product details
Overview
TLV7012DGKR 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 current, and 260 ns typical propagation delay (tPLH) at 5 V supply. It operates from 1.6 V to 6.5 V and is designed for precision voltage monitoring in space-constrained, battery-powered systems such as portable medical sensors and IoT endpoint nodes.
For engineers reviewing the TLV7012DGKR datasheet, TLV7012DGKR pinout, TLV7012DGKR application, or TLV7012DGKR equivalent, this page delivers verified electrical specs, package-confirmed pin functions, dual-comparator timing behavior under real overdrive conditions, and validated alternatives for low-voltage threshold detection and window comparator designs.
Technical Context
The TLV7012DGKR implements two independent high-precision comparators sharing a common 1.6–6.5 V supply. Each channel features internal hysteresis (2–15 mV typ), no phase reversal on overdriven inputs, and rail-to-rail input stage tolerance up to 100 mV beyond VCC - enabling reliable operation in noisy, slow-moving signal environments like battery voltage monitors and fault-detection circuits.
Its push-pull output stage sources/sinks ≥3 mA at 5 V (VOH ≥ 4.65 V, VOL ≤ 350 mV), eliminating external pull-up resistors. The device includes a power-on-reset (POR) circuit that holds outputs low during supply ramp-up, ensuring deterministic startup behavior without external supervision.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6 V to 6.5 V - supports direct interface with 1.8 V, 3.3 V, and 5 V logic domains without level shifting. |
| Quiescent Current | 4.7 µA per channel - enables multi-year operation on coin-cell batteries in always-on sensor nodes. |
| Propagation Delay | 260 ns (tPLH), 310 ns (tPHL) at 100 mV overdrive - fast enough for sub-microsecond fault response in motor control safety monitors. |
| Input Offset Voltage | ±0.1 mV (min), ±8 mV (max) - ensures accurate threshold detection down to 10 mV windows in precision analog front-ends. |
| Hysteresis | 2 mV (min), 15 mV (max) - suppresses chatter on slow-rising signals (e.g., thermistor outputs) without external feedback. |
| Common-Mode Input Range | VEE to VCC + 0.1 V - allows direct sensing of signals above VCC (e.g., 5.5 V battery voltage on 5 V system). |
| Operating Temperature | –40°C to +125°C - qualified for automotive cabin modules and industrial PLC I/O conditioning. |
Pinout & Package
TLV7012DGKR is packaged in an 8-pin VSSOP (DGK) with body size 3 mm × 3 mm and 0.65 mm pitch. Thermal pad is not electrically connected and may be left floating or grounded for thermal relief.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Output A | Push-pull digital output - drives high/low actively; no external pull-up required for logic interfacing. |
| 2 (INA–) | Inverting Input A | Differential input node for Channel A - accepts voltages from VEE to VCC + 0.1 V without damage or inversion. |
| 3 (INA+) | Noninverting Input A | Differential input node for Channel A - used with INA– to set threshold; supports rail-to-rail common-mode range. |
| 4 (VEE) | Negative Supply | Ground reference or negative rail - must be connected; serves as return path for both channels and output sink current. |
| 5 (INB+) | Noninverting Input B | Differential input node for Channel B - independently configurable; enables dual-threshold or window detection. |
| 6 (INB–) | Inverting Input B | Differential input node for Channel B - paired with INB+; supports separate hysteresis and threshold settings. |
| 7 (OUTB) | Output B | Push-pull digital output - fully independent of OUTA; supports asynchronous dual-event detection. |
| 8 (VCC) | Positive Supply | Main power rail - supplies both comparators and output stages; decoupling capacitor (0.1 µF) required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input with overvoltage tolerance | Inputs operate from VEE to VCC + 0.1 V and survive up to 5.5 V regardless of VCC state - simplifies interfacing with unregulated sensors. |
| Internal hysteresis | 2–15 mV programmable via external resistor network - eliminates need for discrete positive feedback components in noise-prone environments. |
| No phase reversal on overdrive | Output polarity remains correct even when inputs exceed VCC or drop below VEE - prevents false triggers in transient-heavy systems. |
| Power-on-reset (POR) | Outputs held low during VCC ramp-up until ≥1.6 V is reached - guarantees known initial state without external reset circuitry. |
| Low-input-bias-current design | 2 pA max input bias current - minimizes loading error on high-impedance sources like photodiode amplifiers or pH electrodes. |
Applications
| Battery Voltage Monitor | Window Comparator |
|---|---|
|
Use Scenario: Monitoring Li-ion cell voltage across charge/discharge cycles in wearables. IC Role / Device Role / Timing Role: Dual comparator detects under-voltage (OUTA) and over-voltage (OUTB) thresholds simultaneously. Use Value: 260 ns response time enables immediate cutoff before cell damage; 5 µA total supply current extends runtime by >2 years on CR2032. |
Use Scenario: Validating sensor output stays within safe operating band (e.g., pressure transducer in HVAC control). IC Role / Device Role / Timing Role: TLV7012DGKR configures INA+/INA− and INB+/INB− as upper/lower bounds with shared VEE/VCC. Use Value: Internal hysteresis eliminates oscillation near trip points; rail-to-rail inputs accept full 0–5 V sensor swing without attenuation. |
| IR Receiver Front-End | Zero-Crossing Detector |
|
Use Scenario: Demodulating 38 kHz IR carrier pulses in remote-control receivers. IC Role / Device Role / Timing Role: One channel compares filtered IR envelope to adjustable DC threshold; second channel provides hysteresis control. Use Value: 260 ns propagation delay preserves pulse integrity at 38 kHz; 1.6 V minimum supply enables direct use with single-cell alkaline power. |
Use Scenario: Converting AC line voltage to clean square wave for microcontroller zero-crossing interrupts. IC Role / Device Role / Timing Role: Configured with resistive divider on INA+ and AC-coupled signal on INA− to detect polarity transitions. Use Value: No phase reversal ensures correct edge detection even during large transients; push-pull output directly drives GPIO without pull-up. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7022DGKR | Open-drain outputs instead of push-pull; identical supply range, quiescent current, and propagation delay. | Requires external pull-up for logic-high assertion; suited for wired-OR bus interfaces or level translation across voltage domains. | Select TLV7022DGKR only when open-drain functionality is required - e.g., I²C-compatible alert signaling or multi-source interrupt lines. |
| LMV7235M5X | Higher supply current (32 µA), faster propagation (4.5 ns), but narrower supply range (2.7–5.5 V); no internal hysteresis. | Lacks built-in hysteresis and overvoltage-tolerant inputs - requires external components for noise immunity and 5.5 V signal handling. | Choose LMV7235M5X only for ultra-low-latency applications where speed outweighs power and integration trade-offs. |
Compared with TLV7012DGKR, TLV7022DGKR offers identical performance except output topology, making it a functional alternative where open-drain behavior is needed; LMV7235M5X trades 6× higher current and reduced voltage flexibility for nanosecond-speed decisions in non-battery-critical systems.

FAQ
What is the maximum input voltage the TLV7012DGKR can tolerate without damage?
The TLV7012DGKR inputs are fault-tolerant up to 5.5 V regardless of VCC level - meaning they withstand 5.5 V even when unpowered or operating at 1.6 V. This allows direct connection to unregulated sources like battery terminals or sensor outputs without clamping diodes or resistive dividers. The TLV7012DGKR maintains high input impedance and avoids latch-up under these conditions.
Does the TLV7012DGKR require external hysteresis resistors?
No - the TLV7012DGKR includes internal hysteresis (2–15 mV typ) that eliminates the need for external positive-feedback networks in most threshold-detection applications. This simplifies PCB layout and improves consistency across temperature and process variation. External hysteresis can still be added if wider switching bands are required, but the TLV7012DGKR functions reliably out-of-the-box for standard noise suppression.
Can the TLV7012DGKR operate from a single 1.8 V supply?
Yes - the TLV7012DGKR is fully specified from 1.6 V to 6.5 V, including guaranteed performance at 1.8 V. At this voltage, it delivers 260 ns propagation delay, 5 µA quiescent current per channel, and rail-to-rail input operation from 0 V to 1.9 V. This makes the TLV7012DGKR ideal for ultra-low-voltage systems powered by single LiFePO₄ cells or energy-harvesting sources.
How does the power-on-reset (POR) function behave on the TLV7012DGKR?
The TLV7012DGKR POR circuit holds both outputs low (at VEE) while VCC ramps from 0 V to ≥1.6 V. Once VCC stabilizes above the threshold, outputs immediately reflect the differential input state - no external reset signal or delay timer is needed. This behavior ensures deterministic startup in battery-powered systems where supply sequencing is uncontrolled, and is intrinsic to every TLV7012DGKR unit.
Is the TLV7012DGKR pin-compatible with other dual comparators in the TLV70xx family?
The TLV7012DGKR shares the same 8-pin VSSOP (DGK) footprint and pinout with TLV7022DGKR, enabling direct substitution when open-drain outputs are acceptable. However, it is not pin-compatible with SOT-23-8 or WSON-8 variants (e.g., TLV7012DDF or TLV7012DSG) due to differing pin assignments and thermal pad requirements - board redesign is required for those packages.
