Texas Instruments TLV3502AIDR

Overview

TLV3502AIDR from Texas Instruments is a dual, rail-to-rail input/output high-speed comparator with 4.5 ns propagation delay at 100 mV overdrive, 2.7 V to 5.5 V supply range, and push-pull CMOS outputs. It operates across –40°C to +125°C and features 6 mV internal hysteresis for noise immunity-used in high-speed threshold detection within wireless base station front-ends.

For engineers reviewing the TLV3502AIDR datasheet, TLV3502AIDR pinout, TLV3502AIDR application, or TLV3502AIDR equivalent, key selection considerations include propagation delay vs. overdrive voltage, input common-mode range extending 0.2 V beyond rails, dual-channel timing alignment (skew ≤0.5 ns), and SOT-23-8 package compatibility with space-constrained RF signal chains.

Technical Context

The TLV3502AIDR integrates two independent comparators sharing a single supply, each with beyond-the-rails input stage enabling operation with inputs down to (V−) −0.2 V and up to (V+) −0.2 V. Its push-pull output drives CMOS/TTL loads directly without external pull-ups.

Unlike the TLV3501, the TLV3502AIDR omits shutdown functionality-confirmed by absence of SHDN pin in its 8-pin SOT-23 pinout and explicit statement in Section 7.4.1. Propagation delay remains stable across temperature (7 ns max from –40°C to +125°C) and load capacitance (≤100 pF), supporting reliable high-frequency window detection.

FAQ

What is the maximum operating temperature for TLV3502AIDR?

The TLV3502AIDR is specified to operate continuously from –40°C to +125°C ambient temperature. This rating is confirmed in Section 6.3 (Recommended Operating Conditions) and applies across the full supply range (2.7 V to 5.5 V). Thermal metrics such as RθJA = 191.6°C/W (SOT-23) ensure reliable junction temperature control under typical PCB layouts.

Does TLV3502AIDR include a shutdown feature?

No, TLV3502AIDR does not include a shutdown feature. Unlike the TLV3501, the TLV3502 family lacks a SHDN pin-explicitly stated in Section 7.4.1 and verified by the 8-pin SOT-23 pinout listing only V+, V−, two inputs per channel, and two outputs. Power management must be handled externally via supply sequencing.

What is the input common-mode voltage range of TLV3502AIDR?

The TLV3502AIDR supports an input common-mode voltage range from (V−) −0.2 V to (V+) −0.2 V, as specified in Section 6.6 (Electrical Characteristics). This beyond-the-rails capability allows direct interfacing with sensors or signals operating near ground or supply rails without level-shifting circuitry.

Can TLV3502AIDR drive TTL logic directly?

Yes, TLV3502AIDR can drive TTL logic directly. Its push-pull CMOS output delivers VOH ≥ (V+) − 30 mV and VOL ≤ (V−) + 30 mV at ±1 mA load (Section 6.6), satisfying TTL VIH(min) = 2.0 V and VIL(max) = 0.8 V when powered from 3.3 V or 5 V supplies-no pull-up resistor required.

What is the propagation delay skew between channels in TLV3502AIDR?

The propagation delay skew between Channel A and Channel B of TLV3502AIDR is ≤0.5 ns under typical conditions (ΔVIN = 100 mV, overdrive = 20 mV, TA = 25°C), as documented in Section 6.7 (Switching Characteristics). This tight skew enables synchronized dual-threshold decisions critical for window detection and phase-aligned signal processing.
