Product details
Overview
TLV7211AIDCKT 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 TLV7211AIDCKT datasheet, TLV7211AIDCKT pinout, TLV7211AIDCKT application, or TLV7211AIDCKT equivalent, key selection criteria include input offset voltage tolerance, rail-to-rail common-mode range, push-pull output drive capability without external pull-up, power-on reset behavior, and SC-70 (DCK) package compatibility with space-constrained portable PCB layouts.
Technical Context
The TLV7211AIDCKT implements a CMOS comparator core 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 current. 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 light/magnetic sensor interfaces |
| Supply Current (typ) | 7 μA at 5 V - allows multi-year operation on coin-cell batteries in always-on monitoring applications |
| Propagation Delay (tPLH) | 420 ns at 5 V, 100 mV overdrive - ensures sub-microsecond decision latency for fast alarm triggering |
| Input Common-Mode Range | VCC– – 0.3 V to VCC+ + 0.3 V - permits direct connection to sensors operating at rail extremes (e.g., photodiode amps) |
| Output Type | Push-pull CMOS - eliminates external pull-up resistor, reduces BOM count, and improves rise/fall time consistency |
| Power-On Reset | Holds OUT low for ≤200 µs during VCC ramp - prevents spurious output transitions at power-up in safety-critical status monitoring |
Pinout & Package
TLV7211AIDCKT is housed in a 6-pin SC-70 (DCK) package, measuring 2.0 mm × 1.25 mm × 0.9 mm (max height), 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-signal loads directly; no external pull-up required |
| 2 | VCC+ | Positive supply terminal - accepts 2.7–15 V; decoupling capacitor placement critical for noise immunity |
| 3 | IN+ | Non-inverting input - high-impedance (0.04 pA bias) node for reference or sensor signal routing |
| 4 | NC | No internal connection - must be left floating; not usable as thermal pad or ground tie |
| 5 | IN− | Inverting input - matched to IN+ for differential sensing; common-mode range extends beyond rails |
| 6 | VCC− | Negative supply / ground terminal - return path for supply current and output sink current |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Operates with inputs from VCC− −0.3 V to VCC+ +0.3 V - enables direct interfacing with op-amp outputs or rail-swing sensors |
| Integrated power-on reset (POR) | Guarantees known low-output state during power sequencing - eliminates need for external reset circuitry in portable devices |
| Ultra-low supply current | 7 μA typical at 5 V - reduces system standby power by >90% vs. legacy bipolar comparators |
| Push-pull CMOS output | Drives capacitive loads up to 50 pF with 15 ns rise/fall times - supports clean digital signaling without external components |
| Low input offset voltage drift | 1 μV/°C (25°C) - maintains threshold accuracy across temperature in automotive cabin sensors or industrial monitors |
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), otherwise identical electrical specs and pinout | Suitable for less precision-critical applications like generic voltage monitoring where 10 mV extra offset is acceptable | Select TLV7211IDCKR only if cost sensitivity outweighs need for <5 mV offset in sensor thresholding |
| LMV331IDBVR | Higher 100 μA supply current, 200 ns propagation delay, open-drain output requiring external pull-up | Requires additional resistor; less suitable for ultra-low-power or space-constrained designs | Choose LMV331IDBVR only if higher speed and wider supply range (2.7–5.5 V) justify increased current and layout overhead |
Compared with TLV7211IDCKR and LMV331IDBVR, TLV7211AIDCKT delivers the lowest offset voltage and lowest quiescent current in the SC-70 package, making it optimal for precision, battery-sensitive applications where board area and power budget are tightly constrained.

FAQ
What is the maximum supply voltage rating for TLV7211AIDCKT?
The absolute maximum supply voltage (VCC+ – VCC−) for TLV7211AIDCKT is 16 V. The recommended operating range is 2.7 V to 15 V. Exceeding 16 V risks permanent damage per Absolute Maximum Ratings in the datasheet. Operation above 15 V is not characterized and may degrade performance or reliability of TLV7211AIDCKT.
Does TLV7211AIDCKT have an internal power-on reset function?
Yes, TLV7211AIDCKT 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 reset components-critical for reliable operation in TLV7211AIDCKT-based alarm and status monitoring systems.
What is the input bias current specification for TLV7211AIDCKT?
The input bias current for TLV7211AIDCKT is 0.04 pA (typical) at 25°C. This ultra-low value minimizes loading error on high-impedance sources such as photodiode transimpedance amplifiers or passive sensor bridges, preserving signal integrity in precision TLV7211AIDCKT implementations.
Can TLV7211AIDCKT operate with dual supplies?
Yes, TLV7211AIDCKT supports dual-supply operation (e.g., ±5 V) as well as single-supply configurations. Its rail-to-rail input common-mode range extends 0.3 V beyond both supply rails, allowing use with split supplies while maintaining full input dynamic range-enabling flexible TLV7211AIDCKT integration in mixed-signal test equipment or audio signal detectors.
Is TLV7211AIDCKT pin-compatible with other comparators in SC-70 packages?
TLV7211AIDCKT uses a 6-pin SC-70 (DCK) footprint with pin 1 = OUT, pin 2 = VCC+, pin 3 = IN+, pin 4 = NC, pin 5 = IN−, pin 6 = VCC−. While physically compatible with other DCK-packaged comparators, functional pinout differs-e.g., LMV331IDBVR (SOT-23-5) and TLV3604DBVR (SC-70-6) assign different functions to each pin. Direct replacement requires verification of both pin mapping and electrical behavior for TLV7211AIDCKT.
