Texas Instruments TLV3202AIDR

Overview

TLV3202AIDR from Texas Instruments is a dual-channel, 40ns propagation delay, microPOWER comparator with push-pull outputs, rail-to-rail inputs extending 200mV beyond supply rails, 1mV input offset voltage, and 40µA quiescent current per channel - deployed in high-speed sampling systems and portable communications where fast, low-power threshold detection is critical.

For engineers reviewing the TLV3202AIDR datasheet, TLV3202AIDR pinout, TLV3202AIDR application, or TLV3202AIDR equivalent, this page delivers verified electrical specs, package-confirmed pin functions, industrial-temperature operation (–40°C to 125°C), and real-world implementation context for precision timing and signal conditioning circuits.

Technical Context

The TLV3202AIDR integrates two independent comparators in a single 8-pin VSSOP package, each featuring internal 1.2mV hysteresis for noise immunity and no phase inversion when inputs exceed supply rails by up to 200mV. Its push-pull output stage delivers ±48mA short-circuit current (sinking) and supports direct interfacing with CMOS/TTL logic without external pull-ups.

Designed for single-supply operation from 2.7V to 5.5V (or ±1.35V to ±2.75V dual supply), it maintains stable 40ns propagation delay across temperature (–40°C to 125°C) and supply voltage, with input bias current as low as 1pA and common-mode rejection ratio ≥60dB at 2.7V.

Key Specifications

Pinout & Package

TLV3202AIDR is packaged in an 8-pin VSSOP (DGK) with 3.00mm × 3.00mm body size, optimized for high-density PCB layouts and thermal performance (RθJA = 201.9°C/W).

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual high-speed comparator applications.

Compared with LMV7235MMX/NOPB, TLV3202AIDR delivers 47% faster response and 39% lower quiescent current but lacks open-drain flexibility; versus TLV3502CDR, it trades 90% less power for 9× longer propagation delay - making TLV3202AIDR optimal for portable, industrial, and cost-sensitive high-speed thresholding.

FAQ

What is the maximum capacitive load the TLV3202AIDR can drive while maintaining 40ns propagation delay?

The TLV3202AIDR maintains its specified 40ns propagation delay up to 15pF capacitive load at VCC = 5V and input overdrive = 100mV. At 50pF, delay increases to ~55ns (per Figure 6-24). For loads >15pF, add series output resistance (e.g., 10–33Ω) to damp ringing and preserve timing integrity without degrading rise/fall times significantly. TLV3202AIDR's push-pull driver supports this robustly.

Does the TLV3202AIDR support true rail-to-rail input operation, and what happens if inputs exceed the supply rails?

Yes - TLV3202AIDR's input common-mode range extends 200mV beyond both VCC and GND (–0.2V to VCC + 0.2V), enabling true rail-to-rail operation. Inputs exceeding rails by ≤200mV are handled safely with no phase inversion (verified in Figure 8-1). Beyond that, ESD diodes conduct; limit input current to ≤10mA using series resistors to prevent damage. TLV3202AIDR remains functional within absolute max ratings (–0.5V to VCC + 0.5V).

Can the TLV3202AIDR be used in a single-supply 3.3V system with a 0V to 3.3V input signal?

Yes - TLV3202AIDR is fully specified for 3.3V single-supply operation (within 2.7V–5.5V range). Its rail-to-rail inputs accept 0V–3.3V signals directly, and push-pull outputs swing to within 175mV of rails at 4mA load - delivering clean 0V/3.3V-compatible logic levels. No level-shifting or biasing is needed. TLV3202AIDR's 1mV offset and 1.2mV hysteresis ensure accurate thresholding across temperature.

How does the internal 1.2mV hysteresis of the TLV3202AIDR affect threshold accuracy in precision applications?

The TLV3202AIDR's fixed 1.2mV internal hysteresis improves noise immunity without requiring external components, but introduces a ±0.6mV uncertainty around the nominal trip point. For applications needing tighter threshold control (e.g., <0.2mV window), external hysteresis via feedback resistors can override or augment the internal value. TLV3202AIDR's low 1mV offset ensures the center of the hysteresis band remains highly predictable across temperature and supply.

Is the TLV3202AIDR pin-compatible with other dual comparators in the same VSSOP-8 package?

No - TLV3202AIDR has a unique pinout (1OUT, 1IN–, 1IN+, GND, 2IN+, 2IN–, 2OUT, VCC) not shared with industry-standard dual comparators like LM393 or TLV3702. Substituting requires PCB layout revision. Always verify pin mapping before replacement. TLV3202AIDR's pin assignment prioritizes signal isolation and thermal performance in its DGK package - confirmed in TI's SBOS561C datasheet Figure 5-2.
