Texas Instruments TLV3502AIDCNT

Overview

TLV3502AIDCNT 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 station front-ends and ATE timing paths.

For engineers reviewing the TLV3502AIDCNT datasheet, TLV3502AIDCNT pinout, TLV3502AIDCNT application, or TLV3502AIDCNT equivalent, this page delivers verified electrical specs, dual-channel pin mapping, real-world timing performance at 100 mV overdrive, and validated alternatives for high-speed analog signal conditioning.

Technical Context

The TLV3502AIDCNT integrates two independent comparators sharing a common 2.7–5.5 V supply, each featuring beyond-the-rails input range (V− −0.2 V to V+ −0.2 V), 6 mV internal hysteresis, and rail-to-rail CMOS push-pull outputs capable of driving TTL/CMOS logic directly. No shutdown functionality is present-unlike the TLV3501 variant.

Its 4.5 ns typical propagation delay (at 100 mV overdrive, TA = 25°C) and <0.5 ns channel-to-channel skew enable precise edge detection in high-frequency systems; quiescent current remains stable at 3.2 mA per channel across temperature (−40°C to +125°C) and supply voltage.

FAQ

What is the maximum toggle frequency supported by the TLV3502AIDCNT?

The TLV3502AIDCNT supports a maximum toggle frequency of 80 MHz under specified conditions (50 mV overdrive, VS = 5 V). This value derives directly from its 4.5 ns propagation delay and matched rise/fall times (1.5 ns each), enabling reliable operation in high-speed clock/data recovery and pulse-width modulation circuits. The TLV3502AIDCNT maintains this performance across its full operating temperature range (−40°C to +125°C).

Does the TLV3502AIDCNT include a shutdown feature?

No, the TLV3502AIDCNT does not include a shutdown pin or power-down mode. Unlike the single-channel TLV3501, the TLV3502AIDCNT is designed as a dual comparator without shutdown functionality. Its quiescent current remains fixed at 3.2 mA per channel across the full supply range (2.7 V to 5.5 V), making it suitable for always-on high-speed monitoring applications where deterministic latency is critical.

What is the input common-mode voltage range for the TLV3502AIDCNT?

The TLV3502AIDCNT features a beyond-the-rails input common-mode range of V− −0.2 V to V+ −0.2 V. This specification allows the device to accept input signals that extend 200 mV below the negative rail or 200 mV below the positive rail-enabling direct interfacing with sensors, DACs, or attenuated signals without clamping diodes or level-shifting circuitry. This capability is confirmed in Section 6.6 of the SBOS321E datasheet.

Can the TLV3502AIDCNT drive TTL logic directly?

Yes, the TLV3502AIDCNT can drive TTL logic directly due to its rail-to-rail push-pull CMOS output stage. At IO = ±1 mA, the output swing is within 30–50 mV of the supply rails, ensuring VOH exceeds 2.4 V and VOL remains below 0.4 V when powered from 3.3 V or 5 V supplies-meeting standard TTL voltage thresholds. This eliminates the need for external pull-up resistors or buffer stages in mixed-logic systems.

What package type is used for the TLV3502AIDCNT?

The TLV3502AIDCNT uses an 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 of the SBOS321E datasheet and is distinct from the SOIC-8 variant (TLV3502IDR). The DCN package supports high-density PCB layouts in portable and RF-sensitive applications where thermal and parasitic constraints demand minimal footprint.
