Product details
Overview
TLV7211IDR from Texas Instruments is a micropower CMOS comparator with rail-to-rail input, push-pull output, 15 mV max input offset voltage, 7 μA typical supply current at 5 V, and 420 ns typical propagation delay (low-to-high) at 5 V. It operates from 2.7 V to 15 V and is used in battery-powered sensor interface circuits where low quiescent current and direct capacitive load driving are critical.
For engineers reviewing the TLV7211IDR datasheet, TLV7211IDR pinout, TLV7211IDR application, or TLV7211IDR equivalent, this page delivers verified functional identity, SOIC-8 package mapping, confirmed rail-to-rail input range beyond supply rails, push-pull output drive capability without external pull-up, and Power-on Reset behavior holding output low during supply ramp.
Technical Context
The TLV7211IDR implements a CMOS input stage with ultra-low input bias current (0.04 pA typ) and rail-to-rail common-mode input range extending 0.3 V beyond VCC– and VCC+, enabling direct interfacing with sensors operating near supply rails. Its push-pull output stage sinks and sources up to 30 mA/45 mA respectively and drives capacitive loads directly without external components.
An integrated Power-on Reset (POR) circuit holds the output low for up to 200 µs after V+ crosses 1.7 V during power-up or power-down, ensuring known state initialization. The device supports single-supply (2.7 V to 15 V) or dual-supply operation and maintains stable performance across –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 15 V - enables use in both low-voltage portable systems and industrial 12 V rails without level-shifting. |
| Input Offset Voltage (max) | 15 mV at 25°C - defines worst-case decision threshold error in precision threshold detection applications. |
| Supply Current (typ) | 7 μA at 5 V, VOUT = low - supports multi-year battery life in always-on sensor wake-up circuits. |
| Propagation Delay (tPLH) | 420 ns at 5 V, 100 mV overdrive - determines minimum detectable pulse width in fast edge-detection systems. |
| Output Type | Push-pull CMOS - eliminates need for external pull-up resistor, reduces BOM count, and enables direct driving of logic inputs or small capacitive loads. |
| Input Common-Mode Range | VCC– – 0.3 V to VCC+ + 0.3 V - allows input signals to swing beyond supply rails, critical for direct photodiode or bridge sensor interfacing. |
| Power-on Reset Behavior | Output held low for ≤200 µs during V+ ramp - prevents spurious output transitions during power sequencing in microcontroller-based systems. |
Pinout & Package
TLV7211IDR is housed in an 8-pin SOIC (D) package per JEDEC MS-012, with 1.27 mm lead pitch, 3.91 mm × 4.90 mm body, and 1.75 mm max height. Pin 1 is located at the top-left corner with notch or index mark on the package top side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN– | Inverting input - accepts reference or feedback signal; rail-to-rail capable down to VCC– – 0.3 V. |
| 2 | IN+ | Non-inverting input - accepts sensed signal; rail-to-rail capable up to VCC+ + 0.3 V. |
| 3 | OUT | CMOS push-pull output - actively drives high (to VCC+) or low (to VCC–); no external pull-up required. |
| 4 | VCC– | Negative supply or ground terminal - must be connected; serves as output low reference and input common-mode lower bound. |
| 5 | VCC+ | Positive supply terminal - supplies internal bias and defines output high level and input upper common-mode limit. |
| 6–8 | NC | No internal connection - electrically isolated; must remain unconnected per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input | Input common-mode range extends 0.3 V beyond both supply rails, enabling direct interface with sensors whose outputs swing near GND or VCC. |
| Push-pull output | Eliminates need for external pull-up resistors, reducing board space, power loss, and signal rise time variability in logic-level interfacing. |
| 7 μA supply current (typ) | Enables >10-year battery life in coin-cell-powered wake-up comparators when paired with low-duty-cycle microcontrollers. |
| Integrated Power-on Reset | Holds OUT low during V+ ramp-up/down, preventing false triggers in power-sensitive control loops and sequenced systems. |
| 2.7 V to 15 V operation | Single-part support across multiple supply domains - from 3.3 V IoT nodes to 12 V automotive subsystems - simplifying BOM management. |
Applications
| Light Sensor Threshold Detection | Battery Voltage Monitor |
|---|---|
|
Use Scenario: Detecting ambient light level crossing a preset threshold to enable/disable display backlight in portable devices. IC Role / Device Role / Timing Role: Comparator comparing photodiode amplifier output against a fixed reference voltage; rail-to-rail input accommodates near-GND signal swing.

| Alarm Circuit Input Stage | Direct Magnetic Sensor Interface |
|
Use Scenario: Converting analog output from PIR or smoke detector front-end into clean digital alarm signal for microcontroller input. IC Role / Device Role / Timing Role: High-impedance comparator with <0.1 pA input bias accepting weak sensor signals; POR prevents false alarms during power cycling. Use Value: Input common-mode range down to VCC– – 0.3 V allows direct connection to op-amp output stages biased at GND in single-supply designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7211AIDR | 5 mV max input offset voltage vs. 15 mV for TLV7211IDR; otherwise identical specs and pinout. | Suitable for higher-precision threshold detection (e.g., medical sensor alerts), where 10 mV VOS reduction improves accuracy. | Select TLV7211AIDR when tighter offset tolerance is required; same SOIC-8 footprint and layout compatibility. |
| LMV331M5X/NOPB | Higher 100 μA supply current, open-drain output requiring external pull-up, 200 ns response time, 1.8 V to 5.5 V supply range. | Better suited for ultra-fast, low-voltage logic-level comparison but incompatible with rail-to-rail input or push-pull drive requirements. | Choose LMV331M5X/NOPB only for sub-5 V, speed-critical designs where external pull-up is acceptable and input range beyond rails is unnecessary. |
Compared with TLV7211AIDR, TLV7211IDR trades 10 mV higher input offset for broader availability and lower cost in volume production; compared with LMV331M5X/NOPB, it delivers rail-to-rail input, push-pull output, and 14× lower quiescent current at the expense of slightly slower response and wider supply range.

FAQ
What is the maximum supply voltage rating for TLV7211IDR?
The absolute maximum supply voltage (VCC+ – VCC–) for TLV7211IDR is 16 V. Continuous operation above 15 V is not recommended; the device is characterized and specified for reliable operation from 2.7 V to 15 V across –40°C to +85°C. Exceeding 16 V risks permanent damage per Absolute Maximum Ratings.
Does TLV7211IDR support dual-supply operation?
Yes, TLV7211IDR supports dual-supply operation: VCC+ and VCC– can be independently biased (e.g., +5 V and –5 V), enabling true bipolar input signal handling. The input common-mode range extends 0.3 V beyond each rail, and the push-pull output swings fully between the two supplies.
Is TLV7211IDR pin-compatible with TLV7211AIDR?
Yes, TLV7211IDR and TLV7211AIDR share identical SOIC-8 (D) package, pinout, and electrical interface. The only difference is input offset voltage specification: 15 mV max for TLV7211IDR versus 5 mV max for TLV7211AIDR. No PCB changes are required for substitution.
What is the purpose of the NC pins on TLV7211IDR?
Pins 6, 7, and 8 of TLV7211IDR are marked NC (No internal connection) in the datasheet and must remain unconnected on the PCB. These pins have no internal bond wires or circuitry; routing traces or applying solder to them may cause mechanical stress or unintended coupling and is strictly prohibited.
How does the Power-on Reset (POR) function affect TLV7211IDR output behavior?
During power-up or power-down, TLV7211IDR's internal POR circuit holds the OUT pin low for up to 200 µs after V+ crosses 1.7 V. This ensures a defined initial state regardless of input conditions, preventing erratic MCU interrupts or latch-up in downstream logic - a key reliability feature absent in many generic comparators.
