Product details
Overview
TLV3502AIDCNTG4 from Texas Instruments is a dual, rail-to-rail input/output high-speed comparator with 4.5 ns propagation delay, 2.7 V to 5.5 V supply operation, and push-pull CMOS outputs-designed for threshold detection in wireless base stations and automatic test equipment.
For engineers reviewing the TLV3502AIDCNTG4 datasheet, TLV3502AIDCNTG4 pinout, TLV3502AIDCNTG4 application, or TLV3502AIDCNTG4 equivalent, key selection criteria include propagation delay vs. overdrive voltage, input common-mode range extending 0.2 V beyond rails, and dual-channel timing synchronization in high-frequency window comparators.
Technical Context
The TLV3502AIDCNTG4 implements a fully differential, high-gain comparator core with internal 6 mV hysteresis for noise immunity and operates across −40°C to +125°C. Its push-pull output stage drives CMOS/TTL loads directly without external pull-ups.
Input common-mode range spans (V−) −0.2 V to (V+) −0.2 V, enabling robust operation near supply rails. Unlike the TLV3501, the TLV3502AIDCNTG4 lacks a shutdown pin-confirmed by device functional mode documentation and pin function tables.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 4.5 ns typical at 100-mV overdrive - enables ≤80 MHz toggle frequency in high-speed sampling circuits |
| Supply Voltage Range | 2.7 V to 5.5 V - supports single-supply operation in battery-powered and industrial 3.3 V/5 V systems |
| Input Common-Mode Range | (V−) −0.2 V to (V+) −0.2 V - allows direct sensing of signals near ground or VCC without level-shifting |
| Output Type | Rail-to-rail push-pull CMOS - eliminates need for external pull-up resistors and ensures fast rise/fall times (1.5 ns each) |
| Input Offset Voltage | ±1 mV typical - provides precise threshold detection with minimal calibration overhead in precision comparators |
| Quiescent Current | 3.2 mA at 5 V - balances speed and power for portable instrumentation and ATE front-end stages |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial control environments |
Pinout & Package
TLV3502AIDCNTG4 is packaged in an 8-pin SOT-23 (DCN) with body size 1.63 mm × 2.90 mm, optimized for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3502CDR | Same die, SOIC-8 package (3.91 mm × 4.90 mm); higher RθJA (116.4°C/W vs. 191.6°C/W) | Better thermal performance in high-density layouts; requires larger PCB area | Select when board space permits and thermal management prioritizes junction-to-ambient conduction |
| LMH7322MA/NOPB | 2.5 ns propagation delay, 3.3 V only, no rail-to-rail input; higher quiescent current (7.5 mA) | Targeted at ultra-high-speed ADC drivers and RF IF stages-not suitable for low-voltage or rail-sensing use cases | Choose only when sub-3 ns timing is mandatory and supply is fixed at 3.3 V with ample power budget |
Compared with TLV3502CDR and LMH7322MA/NOPB, the TLV3502AIDCNTG4 uniquely combines 4.5 ns speed, rail-to-rail input, dual-channel synchronization, and 2.7–5.5 V flexibility in a space-saving SOT-23 package-making it optimal for portable and thermally constrained high-speed comparator applications.

FAQ
What is the maximum operating frequency of TLV3502AIDCNTG4 in toggle mode?
The TLV3502AIDCNTG4 supports a maximum toggle frequency of 80 MHz under 50 mV overdrive and 5 V supply conditions, as specified in the Switching Characteristics table. This capability stems from its 4.5 ns propagation delay and matched 1.5 ns rise/fall times, making TLV3502AIDCNTG4 suitable for high-speed clock/data recovery and pulse-width modulation applications.
Does TLV3502AIDCNTG4 include a shutdown feature?
No, TLV3502AIDCNTG4 does not include a shutdown pin. The shutdown functionality is exclusive to the TLV3501 variant, as confirmed in Section 7.4.1 and Pin Functions tables. TLV3502AIDCNTG4 operates continuously when powered within its recommended voltage range (2.7 V to 5.5 V), and TLV3502AIDCNTG4 draws 3.2 mA quiescent current at 5 V.
What is the input common-mode voltage range for TLV3502AIDCNTG4?
The input common-mode voltage range for TLV3502AIDCNTG4 is (V−) −0.2 V to (V+) −0.2 V, meaning it accepts signals 0.2 V below ground or 0.2 V below V+-a "beyond-the-rails" capability critical for low-voltage sensing. This specification is validated across the full −40°C to +125°C operating temperature range and applies to both channels of TLV3502AIDCNTG4.
Can TLV3502AIDCNTG4 drive TTL logic directly?
Yes, TLV3502AIDCNTG4 can drive TTL logic directly due to its rail-to-rail push-pull CMOS output stage, which delivers VOH ≥ V+ − 50 mV and VOL ≤ V− + 30 mV at ±1 mA load. This meets standard TTL VIH (≥2.0 V) and VIL (≤0.8 V) thresholds when operated from 3.3 V or 5 V supplies-no level-shifter or pull-up resistor is needed for interfacing with TLV3502AIDCNTG4.
What package type is used for TLV3502AIDCNTG4?
TLV3502AIDCNTG4 uses the 8-pin SOT-23 (DCN) package with nominal body dimensions of 1.63 mm × 2.90 mm. This microsize package is explicitly listed in the Device Information table and supports high-density PCB layouts in portable and space-constrained applications-distinct from the SOIC-8 option used by TLV3502CDR.
