Product details
Overview
TLV1701AIDCKR 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 monitoring and overvoltage protection circuits.
For engineers reviewing the TLV1701AIDCKR datasheet, TLV1701AIDCKR pinout, TLV1701AIDCKR application, or TLV1701AIDCKR equivalent, key selection criteria include its rail-to-rail input stage, stable propagation delay vs temperature (–40°C to +125°C), 300 µV typical input offset voltage, open-collector output compatible with up to +36 V pull-up, and SC70-5 package footprint for space-constrained designs.
Technical Context
The TLV1701AIDCKR implements 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 via external pull-up.
It operates with 55 µA per channel quiescent current across full industrial temperature range (–40°C to +125°C) and maintains 560 ns (typ) tPLH and 460 ns (typ) tPHL at 100 mV input overdrive, with propagation delay variation under ±100 ns over temperature and supply.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV1701IDCKR | Same electrical specs but rated for –40°C to +105°C (vs. –40°C to +125°C for TLV1701AIDCKR) | Not suitable for extended-temperature industrial or automotive under-hood use | Select TLV1701AIDCKR when full –40°C to +125°C operation is required; TLV1701IDCKR may reduce cost where ambient stays below +105°C. |
| LMV7215MF/NOPB | Higher quiescent current (80 µA), faster propagation (4.5 ns), push-pull output (no external pull-up needed) | Lacks open-collector flexibility and rail-to-rail input; unsuitable for mixed-voltage wired-OR or ground-sensing | Choose LMV7215MF/NOPB only for ultra-low-delay, single-rail, low-impedance drive needs - not as functional replacement for TLV1701AIDCKR's open-collector rail-to-rail architecture. |
Compared with TLV1701IDCKR and LMV7215MF/NOPB, TLV1701AIDCKR uniquely combines extended temperature rating, rail-to-rail input, open-collector output, and microPower consumption - making it the only option among the three for high-reliability, multi-rail, thermally demanding comparator applications.

FAQ
What supply voltage range does the TLV1701AIDCKR support?
The TLV1701AIDCKR supports a supply voltage range of +2.2 V to +36 V or ±1.1 V to ±18 V. This wide operating range allows direct connection to high-voltage industrial buses or low-voltage battery systems without external regulation. The device remains fully specified across this range, including quiescent current, propagation delay, and input offset voltage, making TLV1701AIDCKR suitable for diverse power architectures.
Does the TLV1701AIDCKR have rail-to-rail input capability?
Yes, the TLV1701AIDCKR features true rail-to-rail input operation, with an input common-mode voltage range extending from V– to V+. This enables accurate sensing of signals at or near the supply rails - for example, detecting undervoltage conditions close to GND or overvoltage near V+ - without requiring input biasing resistors or level-shifting circuitry, simplifying design and reducing component count in TLV1701AIDCKR-based systems.
What is the typical propagation delay of the TLV1701AIDCKR?
The TLV1701AIDCKR has a typical propagation delay of 560 ns for low-to-high transitions (tPLH) and 460 ns for high-to-low transitions (tPHL) at 100 mV input overdrive. These values remain stable across temperature (–40°C to +125°C) and supply voltage (2.2 V to 36 V), with variation under ±100 ns - ensuring predictable timing behavior in fault-detection and monitoring applications using TLV1701AIDCKR.
Can the TLV1701AIDCKR output drive voltages higher than its supply rails?
Yes, the TLV1701AIDCKR features an open-collector output capable of sinking current up to +36 V above the negative supply rail, regardless of the device's own V+ and V– voltages. This allows the TLV1701AIDCKR output to interface directly with higher-voltage logic domains or relay drivers using an external pull-up resistor - a key advantage over push-pull comparators and essential for mixed-voltage system monitoring with TLV1701AIDCKR.
What package type is used for the TLV1701AIDCKR?
The TLV1701AIDCKR is supplied in the SC70-5 (DCK) package: a 5-pin, surface-mount outline measuring 1.25 mm × 2.00 mm with 0.65 mm lead pitch. This compact footprint supports high-density PCB layouts while maintaining adequate thermal dissipation (RθJA = 283.6°C/W) for typical microPower operation. The SC70-5 package is pin-compatible with other TLV1701 variants like DBV (SOT-23-5) and DRL (SOT553-5), enabling layout flexibility for TLV1701AIDCKR integration.
