Texas Instruments TLV3502AIDCNR

Overview

TLV3502AIDCNR from Texas Instruments is a dual, rail-to-rail, high-speed comparator with 4.5 ns propagation delay, 2.7 V to 5.5 V supply operation, and push-pull CMOS outputs. It features beyond-the-rails input common-mode range (−0.2 V to V_S + 0.2 V), 6 mV internal hysteresis, and operates across −40°C to +125°C - used in high-speed threshold detection within wireless base station front-ends.

For engineers reviewing the TLV3502AIDCNR datasheet, TLV3502AIDCNR pinout, TLV3502AIDCNR application, or TLV3502AIDCNR equivalent, key selection criteria include propagation delay vs. overdrive voltage, input offset voltage (±6.5 mV max), output drive capability into 1 mA loads, thermal performance in SOT-23 (R_θJA = 191.6°C/W), and absence of shutdown functionality compared to TLV3501.

Technical Context

The TLV3502AIDCNR implements a fully differential, high-gain comparator core with push-pull CMOS output stage - enabling direct interfacing with both CMOS and TTL logic without external pull-ups. Its input stage supports common-mode voltages extending 0.2 V beyond either supply rail, critical for low-voltage signal conditioning where reference levels sit near supply boundaries.

Unlike the TLV3501, the TLV3502AIDCNR omits shutdown control and integrates two independent comparators in one 8-pin SOT-23 package. Each channel exhibits matched propagation delay skew ≤0.5 ns and operates with quiescent current of 3.2 mA at 5 V - optimized for timing-critical window detection and zero-crossing applications requiring sub-5 ns response.

FAQ

What is the propagation delay specification for TLV3502AIDCNR at 50-mV overdrive?

The TLV3502AIDCNR has a typical propagation delay of 7.5 ns at 50-mV overdrive and 25°C, with a maximum of 10 ns across −40°C to +125°C. This value is measured between 10% and 90% of V_S and reflects worst-case timing uncertainty when input slew rate or noise reduces effective overdrive - critical for jitter-sensitive sampling applications.

Does TLV3502AIDCNR include a shutdown feature like TLV3501?

No, TLV3502AIDCNR does not include a shutdown pin or function. The TLV3501 provides SHDN control, but TLV3502AIDCNR is a dual comparator without shutdown capability - confirmed in the device functional modes section of the SBOS321E datasheet. Power reduction must be achieved externally via supply gating.

What is the input common-mode voltage range for TLV3502AIDCNR?

The TLV3502AIDCNR supports an input common-mode voltage range from (V−) −0.2 V to (V+) + 0.2 V - verified across the full −40°C to +125°C temperature range. This beyond-the-rails capability allows direct connection of AC-coupled signals or references that swing outside the supply domain, such as ±2.5 V sensor outputs on a 3.3 V rail.

Can TLV3502AIDCNR drive a 50-Ω transmission line directly?

TLV3502AIDCNR is not designed for direct 50-Ω line driving. Its push-pull output is specified for ±1 mA loads, corresponding to ~3.3 kΩ minimum at 3.3 V. Driving 50 Ω would exceed output current capability and distort rise/fall times. Use a dedicated high-speed buffer (e.g., THS3201) or series termination for impedance matching.

What package type and dimensions does TLV3502AIDCNR use?

TLV3502AIDCNR uses an 8-pin SOT-23 package (DCN suffix) with nominal body dimensions of 1.63 mm × 2.90 mm and 0.65 mm lead pitch. Thermal resistance is R_θJA = 191.6°C/W - confirmed in Section 6.5 of the SBOS321E datasheet - requiring careful attention to copper area and airflow in thermally constrained layouts.
