Product details
Overview
TLV7211AIDCKR from Texas Instruments is a micropower CMOS comparator with rail-to-rail input, push-pull output, 5 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 fast response.
For engineers reviewing the TLV7211AIDCKR datasheet, TLV7211AIDCKR pinout, TLV7211AIDCKR application, or TLV7211AIDCKR equivalent, key selection criteria include input offset voltage tolerance, push-pull drive capability without external pull-up, power-on reset behavior, and SC-70 package footprint constraints for space-constrained portable designs.
Technical Context
The TLV7211AIDCKR implements a single-channel CMOS comparator 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 drives capacitive loads directly-eliminating need for external pull-up resistors-and delivers ±30 mA short-circuit sourcing/sinking capability. Input bias current is 0.04 pA (typ), enabling high-impedance sensor interfacing without loading error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 15 V - supports single-supply operation in battery-powered systems from Li-ion (3.0–4.2 V) to industrial 12 V rails |
| Input Offset Voltage (max) | 5 mV at 25°C - enables accurate threshold detection in precision analog monitoring applications |
| Supply Current (typ) | 7 μA at 5 V - allows multi-year operation on coin-cell batteries in always-on status-sensing nodes |
| Propagation Delay (tPLH) | 420 ns at 5 V, 100 mV overdrive - ensures timely response to fast-changing sensor signals like optical interrupters |
| Input Common-Mode Range | VCC– – 0.3 V to VCC+ + 0.3 V - permits direct connection to sensors operating at rail extremes without level-shifting |
| Output Type | Push-pull CMOS - eliminates external pull-up resistor, reduces BOM count, and improves rise/fall time consistency |
| Power-On Reset | Holds output low for ≤200 µs during VCC ramp - prevents spurious logic transitions during system startup or brownout recovery |
Pinout & Package
TLV7211AIDCKR is packaged in SC-70 (DCK), a 6-pin surface-mount package measuring 2.0 mm × 1.25 mm × 0.9 mm (L × W × H), optimized for ultra-compact PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | CMOS push-pull output - drives logic inputs or small loads directly; no external pull-up required |
| 2 | VCC+ | Positive supply terminal - accepts 2.7–15 V; must be decoupled locally with 0.1 μF ceramic capacitor |
| 3 | IN+ | Non-inverting input - high-impedance (0.04 pA bias), supports rail-to-rail common-mode range |
| 4 | NC | No internal connection - left unconnected; not electrically tied to die or substrate |
| 5 | IN− | Inverting input - matched to IN+ for <5 mV offset; differential input voltage rating ±supply |
| 6 | VCC− | Negative supply / ground reference - forms return path for supply current and defines output low state |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Accepts input signals from VCC− – 0.3 V to VCC+ + 0.3 V - enables direct interface with sensors spanning full supply range |
| Push-pull output | Drives high/low actively without external components - reduces board area and improves switching consistency vs. open-drain |
| 7 μA supply current (typ) | Enables >10-year battery life in 10-μA average-current wake-on-event systems using coin cells |
| Integrated power-on reset | Guarantees known output state during power sequencing - eliminates need for external supervisor IC in cost-sensitive designs |
| 0.04 pA input bias current | Minimizes voltage error when interfacing with high-output-impedance sources like photodiodes or thermistors |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7211IDCKR | 15 mV max input offset voltage vs. 5 mV for TLV7211AIDCKR; otherwise identical specs and pinout | Suitable where lower accuracy is acceptable (e.g., gross-level battery OK/LOW indication) | Select TLV7211IDCKR for cost-sensitive designs where 15 mV offset meets system threshold margin |
| LMV7215IDBVR | Higher supply current (32 μA typ), faster response (120 ns), but SOT-23-5 (5-pin) vs. SC-70-6 (6-pin) package | Requires PCB layout change; better for speed-critical apps where power budget allows | Choose LMV7215IDBVR only if 120 ns propagation delay is mandatory and SC-70 footprint is not constrained |
Compared with TLV7211IDCKR, TLV7211AIDCKR provides tighter offset for precision sensing; compared with LMV7215IDBVR, it trades speed for 4.6× lower quiescent current and smaller SC-70 footprint-critical for miniaturized battery-operated devices.

FAQ
What is the maximum supply voltage rating for TLV7211AIDCKR?
The absolute maximum supply voltage (VCC+ – VCC−) for TLV7211AIDCKR is 16 V. Operation beyond 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 maximum limits.
Does TLV7211AIDCKR have built-in power-on reset functionality?
Yes, TLV7211AIDCKR integrates a power-on reset (POR) circuit that holds the output low for up to 200 µs when the supply crosses 1.7 V during ramp-up or ramp-down. This ensures deterministic startup behavior without external supervision, a feature confirmed in Section 6.3.2 of the official datasheet.
What is the input offset voltage specification for TLV7211AIDCKR over temperature?
TLV7211AIDCKR has a maximum input offset voltage of 5 mV at 25°C and 8 mV over the full operating temperature range of –40°C to +85°C. This is specified in Table 5.4 (2.7 V), Table 5.5 (5 V), and Table 5.6 (15 V) of the datasheet under "VOS" parameter.
Can TLV7211AIDCKR drive an LED directly from its output?
Yes, TLV7211AIDCKR can drive a standard 2 mA LED directly when configured with VCC+ = 3.3 V or 5 V. Its push-pull output sinks up to 45 mA (IOL) and sources up to 30 mA (IOH), well above typical LED forward current requirements. No current-limiting resistor is needed if the LED's forward voltage drop is close to VCC+.
Is TLV7211AIDCKR pin-compatible with other comparators in the TLV7211 family?
TLV7211AIDCKR shares identical pinout with TLV7211IDCKR (its 15 mV offset variant) in the SC-70-6 package. However, it is not pin-compatible with TLV7211AIDBVR (SOT-23-5) or TLV7211AIDR (SOIC-8), as those use different pin counts and arrangements per package drawings DBV and D.
