Product details
Overview
TLV1701AIDRLT from Texas Instruments is a single-channel, rail-to-rail input microPower comparator with open-collector output, 55 µA quiescent current, 560 ns low propagation delay (low-to-high), and operation across ±1.1 V to ±18 V or +2.2 V to +36 V supply range. It enables precise voltage detection in industrial power supply monitoring and overvoltage protection circuits.
For engineers reviewing the TLV1701AIDRLT datasheet, TLV1701AIDRLT pinout, TLV1701AIDRLT application, or TLV1701AIDRLT equivalent, key selection criteria include input offset voltage (±300 µV typ), temperature stability (–40°C to +125°C), rail-to-rail input stage, open-collector output compatibility with 36 V pull-up, and SOT553-5 package footprint constraints.
Technical Context
The TLV1701AIDRLT uses a rail-to-rail input stage that prevents phase inversion when inputs exceed supply rails, supporting accurate threshold detection near V+ or GND. Its open-collector output allows wired-OR configurations and flexible level-shifting up to 36 V above the negative supply.
Propagation delay remains stable across temperature (–40°C to +125°C) and supply voltage (2.2 V to 36 V), with typical tPLH = 560 ns and tPHL = 460 ns at 100 mV overdrive and 15 pF load. Input bias current stays below 15 nA over full temperature range, enabling high-impedance sensing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2.2 V to +36 V or ±1.1 V to ±18 V - supports wide-input industrial and automotive power rails without external regulation |
| Quiescent Current | 55 µA per channel - enables battery-powered or energy-sensitive system monitoring with minimal standby drain |
| Propagation Delay | 560 ns (low-to-high), 460 ns (high-to-low) - provides fast response for transient overvoltage/undervoltage detection |
| Input Offset Voltage | ±300 µV (typ), ±5.5 mV (max, –40°C to +125°C) - ensures accurate threshold setting in precision window or zero-crossing applications |
| Input Common-Mode Range | Rail-to-rail (V– to V+) - allows direct sensing of signals at ground or supply rail without level-shifting circuitry |
| Output Type | Open-collector - enables wired-OR logic, level translation up to +36 V, and compatibility with multiple pull-up voltages |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial motor control, and harsh-environment embedded systems |
Pinout & Package
SOT553-5 package: 1.20 mm × 1.60 mm ultra-small outline, 0.5-mm pitch, thermally enhanced bottom-exposed pad (no thermal pad connection required in standard layout).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN+ | Noninverting input | Accepts rail-to-rail analog input; phase-inversion immune up to ±0.5 V beyond rails |
| 2 - V– | Negative supply | Reference for dual-supply operation or ground in single-supply systems |
| 3 - IN– | Inverting input | Accepts rail-to-rail analog input; matched bias current with IN+ for low offset drift |
| 4 - OUT | Open-collector output | Sinks current only; requires external pull-up to define logic-high level (up to +36 V) |
| 5 - V+ | Positive supply | Supports up to +36 V; internal ESD clamps limit input swing to ±0.5 V beyond rails |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Enables direct sensing of signals at V– or V+, eliminating need for input biasing resistors in single-supply designs |
| 55 µA quiescent current | Reduces system-level power budget impact in always-on monitoring circuits such as battery backup supervisors |
| 560 ns propagation delay | Supports real-time fault response in overcurrent protection where sub-microsecond latency is critical |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1701IDBVR | SOT-23-5 package (1.60 mm × 2.90 mm); 233.1°C/W RθJA; identical electrical specs | Larger footprint but better thermal performance in high-power-density layouts; compatible PCB rework | Select TLV1701IDBVR when board space permits larger package and junction temperature margin is critical |
| LMV7215M5X | Push-pull output; 1.8 V to 5.5 V supply; 120 ns propagation delay; no rail-to-rail input | Not suitable for high-voltage sensing or level-translating; limited to low-voltage digital systems | Choose LMV7215M5X only for battery-powered 3.3 V logic interfaces requiring faster switching and no external pull-up |
Compared with TLV1701AIDRLT, TLV1701IDBVR offers superior thermal dissipation in continuous-duty monitoring, while LMV7215M5X trades high-voltage flexibility and rail-to-rail input for speed and push-pull simplicity in low-voltage domains.

FAQ
What is the maximum allowable supply voltage for TLV1701AIDRLT?
The absolute maximum supply voltage for TLV1701AIDRLT is +40 V (or ±20 V). Operation beyond this rating risks permanent damage. The recommended operating range is +2.2 V to +36 V (or ±1.1 V to ±18 V), and all electrical specifications are guaranteed within this band. TI specifies 36 V as the maximum functional supply for reliable open-collector output pull-up compatibility.
Does TLV1701AIDRLT support true rail-to-rail input operation?
Yes, TLV1701AIDRLT supports rail-to-rail input operation: its common-mode input voltage range extends from V– to V+, including both supply rails. This is confirmed in the datasheet's "Input Common-Mode Range" specification (–40°C to +125°C) and validated by Figure 18 showing no phase inversion when inputs exceed rails by ±0.5 V.
Can TLV1701AIDRLT drive a 12 V logic interface directly?
Yes - TLV1701AIDRLT's open-collector output can be pulled up to +12 V (or any voltage ≤ +36 V above V–), enabling direct interface to 12 V logic families. No level shifter is needed. The output sink capability is rated at 20 mA short-circuit current, sufficient for driving standard TTL or CMOS inputs with appropriate pull-up resistor selection.
What is the typical input offset voltage drift of TLV1701AIDRLT over temperature?
The typical input offset voltage drift of TLV1701AIDRLT is ±4 µV/°C over –40°C to +125°C, with a maximum of ±20 µV/°C. This value is specified in the Electrical Characteristics table under dVOS/dT and reflects the device's stability in precision threshold applications where temperature-induced drift must remain below 1 mV across full industrial range.
Is TLV1701AIDRLT pin-compatible with other packages in the TLV170x family?
No - TLV1701AIDRLT (SOT553-5) has a unique 5-pin pinout incompatible with SC70-5 (DCK) and SOT-23-5 (DBV) variants due to different terminal ordering. While all TLV1701 variants share identical functionality and electrical specs, PCB layout must be redesigned for SOT553-5; no mechanical or electrical drop-in replacement exists between these packages.
