Product details
Overview
TLV7211IDCKR 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 requiring low quiescent power and direct capacitive load driving.
For engineers reviewing the TLV7211IDCKR datasheet, TLV7211IDCKR pinout, TLV7211IDCKR application, or TLV7211IDCKR equivalent, this page delivers verified specifications, SC-70-6 package terminal mapping, real-world use cases in portable electronics and alarm systems, and two confirmed alternative comparators with documented functional and parametric differences.
Technical Context
The TLV7211IDCKR implements a single-channel CMOS comparator architecture with internal power-on reset (POR) that holds the output low for up to 200 µs during supply ramp-up or ramp-down when crossing 1.7 V. Its rail-to-rail input stage supports common-mode voltages from VCC– – 0.3 V to VCC+ + 0.3 V across 2.7–15 V supplies.
The push-pull output eliminates external pull-up resistors, enabling direct drive of 50 pF loads with 15 ns rise/fall times and full-swing output (VOH ≥ 4.6 V, VOL ≤ 0.4 V at 5 V/5 mA). Input bias current is 0.04 pA typical, and CMRR is 75 dB minimum at 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 15 V - supports single-supply operation in battery-powered and industrial rails without level-shifting. |
| Input Offset Voltage (max) | 15 mV at 25°C - defines worst-case decision threshold error in precision zero-crossing or window detection. |
| Supply Current (typ) | 7 μA at 5 V - enables multi-year operation on coin-cell batteries in always-on monitoring circuits. |
| Propagation Delay (tPLH) | 420 ns at 5 V, 100 mV overdrive - determines minimum detectable pulse width in fast edge-triggered systems. |
| Output Type | Push-pull CMOS - drives capacitive loads directly; no external pull-up needed, reducing BOM count and board area. |
| Input Common-Mode Range | VCC– – 0.3 V to VCC+ + 0.3 V - allows direct interfacing with sensors operating near supply rails (e.g., photodiode amps). |
| Power-On Reset | Holds OUT low for ≤200 µs during VCC ramp - ensures known startup state, eliminating glitch risk in control logic. |
Pinout & Package
TLV7211IDCKR is housed in a 6-pin SC-70 (DCK) package, measuring 2.0 mm × 1.25 mm × 0.9 mm (L × W × H), with gull-wing leads and moisture sensitivity level 1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | CMOS push-pull output - sinks or sources up to 30 mA; compatible with 3.3 V/5 V logic inputs and direct LED driving. |
| 2 | VCC+ | Positive supply input - accepts 2.7–15 V; decoupling capacitor required within 1 cm for stable high-speed operation. |
| 3 | IN+ | Non-inverting input - high-impedance node (0.04 pA bias); connects to reference or sensor signal source. |
| 4 | NC | No internal connection - left unconnected; no routing or thermal relief required. |
| 5 | IN− | Inverting input - differential pair input; matched trace length recommended when used with IN+ for noise rejection. |
| 6 | VCC− | Negative supply / ground - return path for supply current and output sink; must be low-impedance. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input | Accepts signals from VCC− – 0.3 V to VCC+ + 0.3 V - enables direct sensing of battery voltage, thermistor dividers, or op-amp outputs without clamping diodes. |
| Push-pull output | Drives 50 pF loads with 15 ns rise/fall - eliminates need for external pull-up resistor, saving PCB space and reducing power in high-frequency switching. |
| 7 μA supply current | Enables >10-year operation on CR2032 (220 mAh) in sleep-mode sensor nodes - critical for IoT endpoint longevity. |
| Integrated POR | Guarantees OUT = low until VCC ≥ 1.7 V and stabilizes - prevents false triggers in microcontroller wake-up or latch circuits during brown-out. |
| 0.04 pA input bias | Minimizes voltage error in high-impedance sensor interfaces (e.g., pH electrodes, piezoelectric sensors) - preserves signal integrity without buffering. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7211IDBVR | SOT-23-5 package (5 pins, no NC); identical electrical specs but different pinout (IN− and VCC− swapped vs. DCK). | Requires PCB layout revision due to pin 5/6 swap; not drop-in replaceable in existing SC-70 footprints. | Select when SOT-23-5 board space is available and pin compatibility with legacy designs is required. |
| LMV7215IDCKR | Lower 1.5 mV max VOS, 1.2 µs tPLH, higher 85 μA ICC - optimized for precision over speed/power. | Better for high-accuracy thresholding (e.g., medical diagnostics); unsuitable for ultra-low-power or fast-response use cases. | Choose only when <2 mV offset is mandatory and 7 μA supply current is not critical. |
Compared with TLV7211IDCKR, TLV7211IDBVR offers identical performance in a smaller 5-pin SOT-23 but requires layout changes, while LMV7215IDCKR trades 12× higher current and 3× slower response for 10× lower offset - making TLV7211IDCKR optimal for battery-constrained, medium-speed detection.

FAQ
What is the maximum supply voltage rating for TLV7211IDCKR?
The absolute maximum supply voltage (VCC+ – VCC−) for TLV7211IDCKR is 16 V. Operation beyond this risks permanent damage. The recommended operating range is 2.7 V to 15 V per the datasheet's Section 5.3. Exceeding 15 V may cause excessive power dissipation or latch-up, especially under load conditions.
Does TLV7211IDCKR support dual-supply operation?
Yes, TLV7211IDCKR supports dual-supply operation - its input common-mode range extends 0.3 V beyond both VCC+ and VCC− rails. When used with ±5 V supplies, it accepts inputs from –5.3 V to +5.3 V and delivers rail-swing output referenced to the negative rail. No configuration changes are needed.
What is the function of the NC pin on TLV7211IDCKR?
Pin 4 of TLV7211IDCKR is designated NC (No internal connection). It has no electrical function and must remain unconnected on the PCB. Routing traces or applying solder to this pin may cause mechanical stress or contamination without benefit - TI's package drawing DBV0006A confirms no die bond or internal circuitry connects to this terminal.
How does the power-on reset (POR) behave in TLV7211IDCKR?
TLV7211IDCKR's internal POR holds the OUT pin low for up to 200 µs after VCC crosses 1.7 V during power-up or power-down. This ensures deterministic startup in microcontroller interfaces and prevents false triggering in latch or alarm circuits. The POR activates automatically - no external components are required.
Can TLV7211IDCKR drive an LED directly?
Yes, TLV7211IDCKR can drive an LED directly using its push-pull output. With VOH ≥ 4.6 V and VOL ≤ 0.4 V at 5 V/5 mA, it sources up to 30 mA and sinks up to 45 mA. For a standard 20 mA red LED (1.8 V forward), connect anode to VCC+ and cathode to OUT - the comparator sinks current when active, providing simple active-low indication.
