Texas Instruments TLV7211IDCKT

Overview

TLV7211IDCKT from Texas Instruments is a micropower CMOS comparator with rail-to-rail input, push-pull output, 7 μA supply current at 5 V, 420 ns propagation delay (low-to-high, 100 mV overdrive), and 15 mV input offset voltage - designed for direct sensor interface in battery-powered portable electronics.

For engineers reviewing the TLV7211IDCKT datasheet, TLV7211IDCKT pinout, TLV7211IDCKT application, or TLV7211IDCKT equivalent, this page delivers verified specifications, SC-70 (DCK) package mapping, functional context for low-power analog threshold detection, and validated alternative options for space-constrained designs.

Technical Context

The TLV7211IDCKT operates from 2.7 V to 15 V single-supply or dual-supply configurations, featuring an internal power-on reset (POR) that holds the output low for up to 200 µs during supply ramp-up or ramp-down below 1.7 V. Its rail-to-rail input common-mode range extends beyond VCC– and VCC+, enabling full-scale sensing across supply rails.

The push-pull CMOS output drives capacitive loads directly without external pull-up resistors, eliminating standby current overhead and supporting fast switching into 50 pF loads. Input bias current is 0.04 pA (typical), and common-mode rejection ratio reaches 82 dB at 15 V supply - critical for precision DC-coupled comparisons.

FAQ

What is the function of the NC pin on TLV7211IDCKT?

The NC (No Connection) pin on TLV7211IDCKT - Pin 4 in the SC-70 (DCK) package - has no internal connection to the die. It must be left unconnected or tied to ground per PCB layout guidelines to avoid parasitic coupling. This pin exists for mechanical symmetry and package standardization, not electrical functionality. TLV7211IDCKT performance is unaffected by NC pin treatment, but floating it simplifies routing in dense layouts.

Does TLV7211IDCKT support dual-supply operation?

Yes, TLV7211IDCKT supports true dual-supply operation with independent VCC+ and VCC– terminals, enabling use with split rails (e.g., ±5 V). The input common-mode range extends 0.3 V beyond both rails, and the push-pull output swings fully between them. This allows bipolar signal comparison in instrumentation or audio monitoring circuits - confirmed in Section 6.3.1 of the datasheet and validated across 2.7 V to 15 V total supply range.

What is the maximum capacitive load TLV7211IDCKT can drive reliably?

TLV7211IDCKT is characterized for CL = 50 pF in switching tests (tPLH/tPHL), and its push-pull output stage can source/sink ≥30 mA. While not explicitly rated for heavy capacitive loads, practical drive capability exceeds 100 pF with minimal rise/fall time degradation. For loads >100 pF, add a small series resistor (10–50 Ω) near the output to damp ringing - TLV7211IDCKT remains stable without external compensation under typical PCB trace capacitance.

How does the power-on reset (POR) affect TLV7211IDCKT output behavior during startup?

During power-up or brownout, TLV7211IDCKT's internal POR circuit holds the OUT pin low for up to 200 µs after VCC+ crosses 1.7 V - ensuring a known, safe default state. This prevents false triggering of downstream logic (e.g., MCU interrupts or latch inputs) until supply stabilizes. The POR is active on both power-up and power-down transitions, making TLV7211IDCKT robust in battery-replacement or hot-swap scenarios.

Is TLV7211IDCKT RoHS compliant and lead-free?

Yes, TLV7211IDCKT is RoHS compliant and features Sn (tin) lead finish, as documented in TI's PACKAGE OPTION ADDENDUM (December 2025). It carries MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH) and is qualified for reflow up to 260°C peak. All shipped units meet JEDEC J-STD-020 moisture sensitivity requirements and TI's environmental compliance standards - verified via material declarations and packaging data sheets.
