Product details
Overview
TLV7211ID 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 - deployed in battery-powered sensor interfaces and portable electronics.
For engineers reviewing the TLV7211ID datasheet, TLV7211ID pinout, TLV7211ID application, or TLV7211ID equivalent, key selection considerations include its SOIC-8 package, single/dual-supply operation (2.7–15 V), internal power-on reset, rail-to-rail common-mode range beyond VCC±, and low-input-current design for high-impedance signal sources.
Technical Context
The TLV7211ID operates as a precision voltage comparator with a push-pull CMOS output stage that drives capacitive loads directly-eliminating external pull-up resistors. Its internal power-on reset holds the output low for up to 200 µs during supply ramp-up or drop below 1.7 V.
It supports single-supply (e.g., 2.7–15 V between VCC+ and VCC−) or dual-supply configurations. Input common-mode range extends 0.3 V beyond both rails (e.g., –0.3 V to VCC+ + 0.3 V), enabling direct interface with sensors and reference voltages across full supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 15 V - enables use in 3.3 V, 5 V, and 12 V systems without level-shifting |
| Input Offset Voltage (max) | 15 mV at –40°C to 85°C - defines minimum detectable differential voltage in precision threshold detection |
| Supply Current (typ) | 7 μA at 5 V, VOUT = low - supports multi-year battery life in always-on monitoring circuits |
| Propagation Delay (tPLH) | 420 ns at 5 V, 100 mV overdrive - ensures fast response for dynamic signal edge detection |
| Input Bias Current (typ) | 0.04 pA at 25°C - preserves accuracy when interfacing with high-impedance sources like photodiodes or thermistors |
| Rail-to-Rail Input Range | VCM = VCC– – 0.3 V to VCC+ + 0.3 V - allows direct sensing of signals near supply rails without attenuation |
| Output Type | Push-pull CMOS - delivers active high/low drive without external components, reducing BOM count and board space |
Pinout & Package
TLV7211ID is housed in an 8-pin SOIC (D) package per JEDEC MS-012, with 1.27 mm pitch, 3.91 mm × 4.90 mm body, and 1.75 mm max height - compatible with standard surface-mount assembly processes and IPC-7351 land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN–) | Inverting input | Accepts reference or feedback signal; high-impedance node (0.04 pA bias current) |
| 2 (IN+) | Non-inverting input | Accepts sensed signal; rail-to-rail common-mode range supports direct sensor connection |
| 3 (OUT) | Digital output | Push-pull CMOS output drives logic inputs or small loads directly (±30 mA sink/source capability) |
| 4 (VCC–) | Negative supply / ground | Reference return for dual-supply operation or system GND in single-supply mode |
| 5 (NC) | No internal connection | Not bonded; must be left floating or tied to GND per layout best practices |
| 6 (NC) | No internal connection | Not bonded; must be left floating or tied to GND per layout best practices |
| 7 (VCC+) | Positive supply | Accepts 2.7–15 V; powers internal bias and output stage |
| 8 (NC) | No internal connection | Not bonded; must be left floating or tied to GND per layout best practices |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends 0.3 V beyond VCC– and VCC+, enabling direct interface with sensors operating near supply rails |
| Internal power-on reset (POR) | Holds OUT low for up to 200 µs during VCC ramp-up or drop below 1.7 V - prevents undefined startup states |
| Ultra-low quiescent current | 7 μA typical at 5 V supports energy-constrained applications such as coin-cell-powered IoT nodes |
| Push-pull CMOS output | Eliminates need for external pull-up resistor, reducing component count and improving rise/fall time consistency |
| Low input bias current | 0.04 pA typical minimizes voltage error across high-impedance source impedances (>100 MΩ) |
Applications
| Battery-Powered Sensor Monitoring | Portable Device Power Sequencing |
|---|---|
Use Scenario: Continuous voltage monitoring of lithium coin cells or alkaline batteries in wireless sensors. IC Role / Device Role / Timing Role: Comparator detecting end-of-life threshold (e.g., 2.4 V) with rail-to-rail input tracking battery decay curve. Use Value: 7 μA supply current extends operational lifetime beyond 5 years on CR2032; no external pull-up reduces standby leakage. | Use Scenario: Enabling subsystem power rails only after main supply stabilizes in notebooks or PDAs. IC Role / Device Role / Timing Role: Threshold detector comparing regulated 3.3 V rail against precision reference to assert enable signal. Use Value: Internal POR ensures clean, glitch-free enable assertion during cold start; push-pull output drives logic-level input directly. |
| Optical Alarm Trigger | Industrial Status Indicator |
Use Scenario: Light-intensity detection in smoke or intrusion alarms using photodiode amplifier output. IC Role / Device Role / Timing Role: High-impedance comparator accepting transimpedance amplifier output to trigger alarm at preset lux level. Use Value: 0.04 pA input bias avoids loading photodiode circuit; rail-to-rail input accommodates wide dynamic range output swing. | Use Scenario: Real-time monitoring of 4–20 mA loop integrity in PLC I/O modules. IC Role / Device Role / Timing Role: Window comparator (using two TLV7211ID units) detecting open-circuit or short-circuit fault conditions. Use Value: 15 mV max VOS ensures accurate 4 mA and 20 mA threshold detection; SOIC-8 package supports compact dual-channel layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7211AID | 5 mV max input offset voltage vs. 15 mV for TLV7211ID; otherwise identical specs and pinout | Suitable where tighter threshold accuracy is required (e.g., precision voltage monitors) | Select TLV7211AID when <10 mV total error budget demands lower VOS; same SOIC-8 footprint and layout |
| LMV331IDBVR | SOT-23-5 package (5-pin), 2.7–5.5 V supply range, 1.25 mV max VOS, 85 ns response - not pin-compatible | Better speed and offset but limited to ≤5.5 V; requires PCB redesign due to different package and pin count | Choose LMV331IDBVR only if higher speed and lower VOS justify SOT-23-5 re-layout and supply voltage constraint |
Compared with TLV7211AID, TLV7211ID trades offset accuracy for cost and availability in legacy SOIC-8 designs; versus LMV331IDBVR, it offers wider supply range and proven robustness in industrial temperature cycling but at slower response and higher VOS.

FAQ
What is the maximum supply voltage rating for TLV7211ID?
The absolute maximum supply voltage (VCC+ – VCC–) for TLV7211ID is 16 V. Operating continuously above this risks permanent damage. The recommended operating range is 2.7 V to 15 V, validated across –40°C to 85°C junction temperature. Exceeding 15 V may degrade long-term reliability even if within absolute max limits.
Does TLV7211ID support dual-supply operation?
Yes, TLV7211ID supports true dual-supply operation: VCC+ and VCC– can be independently biased (e.g., +5 V and –5 V), enabling symmetric input ranges and bipolar signal comparison. The input common-mode range extends 0.3 V beyond each rail, and the push-pull output swings fully between the applied supplies.
What is the function of the NC pins on TLV7211ID?
TLV7211ID has three NC (no internal connection) pins: pins 5, 6, and 8. These are unconnected die bond pads - not tied to any internal circuitry. They must remain electrically floating or be tied to GND per TI's layout recommendations to avoid parasitic coupling or ESD path disruption.
How does the power-on reset (POR) affect TLV7211ID output behavior?
During power-up or brownout, TLV7211ID's internal POR circuit holds the OUT pin low for up to 200 µs after VCC+ crosses 1.7 V. This guarantees a known state at startup, preventing spurious logic transitions in downstream circuitry - critical for reliable enable sequencing in portable electronics.
Can TLV7211ID drive a 10 kΩ load directly?
Yes, TLV7211ID's push-pull CMOS output can drive a 10 kΩ load directly: at 5 V supply, VOL is 0.2–0.4 V and VOH is 4.6–4.8 V under 5 mA load - well within logic thresholds for 5 V TTL/CMOS. No series resistor or pull-up is needed, simplifying interface design and reducing power loss.
