Texas Instruments TLV1701AIDCKT

Overview

TLV1701AIDCKT from Texas Instruments is a single-channel, rail-to-rail input microPower comparator with open-collector output, operating from 2.2 V to 36 V (±1.1 V to ±18 V), featuring 55 µA quiescent current, 560 ns low propagation delay (low-to-high), and ±300 µV input offset voltage at 25°C - used in overvoltage detection, window comparators, and industrial system monitoring circuits.

For engineers reviewing the TLV1701AIDCKT datasheet, TLV1701AIDCKT pinout, TLV1701AIDCKT application, or TLV1701AIDCKT equivalent, key selection considerations include its wide supply range, stable propagation delay across temperature (–40°C to +125°C), rail-to-rail input stage, open-collector output compatibility with 36 V pull-up, and SC70-5 package footprint for space-constrained designs.

Technical Context

The TLV1701AIDCKT implements a rail-to-rail input stage that prevents phase inversion when inputs exceed supply rails, enabling reliable operation in high-common-mode applications. Its open-collector output supports wired-OR configurations and flexible level-shifting up to 36 V above the negative supply rail.

Designed for low-power industrial sensing, it maintains 55 µA per channel quiescent current across –40°C to +125°C and delivers consistent 460–560 ns propagation delay under 100 mV input overdrive, with input bias current ≤15 nA and PSRR of ≥20 µV/V over full temperature range.

Key Specifications

FAQ

What is the maximum supply voltage rating for TLV1701AIDCKT?

The absolute maximum supply voltage for TLV1701AIDCKT is +40 V (or ±20 V), but recommended operating range is +2.2 V to +36 V (±1.1 V to ±18 V). Exceeding 40 V risks permanent damage. Operation at 36 V enables direct interface with 24 V industrial buses while maintaining full rail-to-rail input functionality and open-collector output compatibility with 36 V pull-up rails.

Does TLV1701AIDCKT support rail-to-rail input operation?

Yes, TLV1701AIDCKT features a true rail-to-rail input stage with common-mode range from V– to V+, verified across –40°C to +125°C. This allows direct sensing of signals at ground or supply rails - for example, detecting battery discharge down to 0 V or monitoring 24 V rail headroom without attenuation networks. Phase inversion is prevented even when inputs exceed supply rails.

What is the typical propagation delay of TLV1701AIDCKT and how does it vary with temperature?

TLV1701AIDCKT has a typical propagation delay of 560 ns (low-to-high) and 460 ns (high-to-low) at 25°C with 100 mV input overdrive. Over –40°C to +125°C, delay remains stable: variation is less than ±100 ns across the full range, as confirmed by Figure 10 in SBOS589D. This stability enables reliable timing in thermal-cycling environments like motor control enclosures or outdoor power converters.

Can TLV1701AIDCKT drive a 12 V logic input directly?

Yes - TLV1701AIDCKT's open-collector output can be pulled up to any voltage up to 36 V above V–, so with V– = 0 V (single supply), a 12 kΩ pull-up to 12 V is fully supported. The output sinks ≥4 mA at 900 mV saturation, ensuring clean TTL/CMOS-compatible logic levels. No level-shifter IC is needed, reducing BOM count and board area.

What package type is used for TLV1701AIDCKT and what are its board-level implications?

TLV1701AIDCKT uses the SC70-5 (DCK) package: 1.25 mm × 2.00 mm, 0.65 mm pitch, 5-pin surface-mount. Its small footprint saves PCB space in dense layouts, while thermal metrics (RθJA = 283.6°C/W) require moderate copper pour for >1 mA continuous output current. The package is compatible with standard reflow profiles and supports automated optical inspection due to exposed pad absence.
