Texas Instruments TLV3502AIDCNRG4

Overview

TLV3502AIDCNRG4 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 TLV3502AIDCNRG4 datasheet, TLV3502AIDCNRG4 pinout, TLV3502AIDCNRG4 application, or TLV3502AIDCNRG4 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-23-8 (R_θJA = 191.6°C/W), and absence of shutdown functionality compared to TLV3501.

Technical Context

The TLV3502AIDCNRG4 implements a fully differential, high-gain comparator core with internal hysteresis and rail-to-rail output stage capable of directly driving CMOS/TTL logic. Its input stage supports common-mode voltages extending 0.2 V beyond either supply rail, enabling robust sensing in low-voltage systems where reference levels approach supply boundaries.

Unlike the TLV3501, the TLV3502AIDCNRG4 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-7 ns response over full temperature range.

FAQ

What is the maximum operating temperature range for TLV3502AIDCNRG4?

The TLV3502AIDCNRG4 is rated for continuous operation from −40°C to +125°C. This extended temperature range is verified per TI's automotive-grade qualification standards and supports deployment in under-hood automotive modules, industrial PLCs, and outdoor telecom equipment where ambient temperatures exceed 105°C.

Does TLV3502AIDCNRG4 include a shutdown feature?

No, TLV3502AIDCNRG4 does not include a shutdown pin or function. Unlike the TLV3501 variant, the TLV3502AIDCNRG4 is designed as a dual comparator with fixed active operation - eliminating control complexity and ensuring deterministic timing behavior in always-on monitoring circuits.

What is the typical propagation delay of TLV3502AIDCNRG4 at 5-V supply and 100-mV overdrive?

The typical propagation delay of TLV3502AIDCNRG4 is 4.5 ns under those conditions, as specified in Section 6.7 of the SBOS321E datasheet. This value is measured between 10% and 90% of V_S at the input and output, with load capacitance of 17 pF, and represents the fastest achievable decision latency for the device.

Can TLV3502AIDCNRG4 drive TTL logic directly?

Yes, TLV3502AIDCNRG4 can drive TTL logic directly due to its push-pull CMOS output stage, which provides rail-to-rail voltage swing (≤50 mV from V+ or V− at ±1 mA). At 5 V supply, VOH exceeds 4.9 V and VOL stays below 50 mV - satisfying TTL VIH(min) = 2.0 V and VIL(max) = 0.8 V with substantial noise margin.

What package type is used for TLV3502AIDCNRG4?

TLV3502AIDCNRG4 uses an 8-pin SOT-23 package (DCN suffix), with nominal body dimensions of 1.63 mm × 2.90 mm. This microsize package supports high-density PCB layouts and is compatible with standard surface-mount assembly processes, including reflow soldering per JEDEC J-STD-020.
