Texas Instruments TLV3502AIDG4

Overview

TLV3502AIDG4 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 operation, and 6 mV internal hysteresis-designed for threshold detection in wireless base station front-ends and automatic test equipment timing paths.

For engineers reviewing the TLV3502AIDG4 datasheet, TLV3502AIDG4 pinout, TLV3502AIDG4 application, or TLV3502AIDG4 equivalent, this page delivers verified electrical specs, dual-channel pin mapping, real-world use cases including window comparators and zero-crossing detection, and two validated alternative parts with documented functional and packaging differences.

Technical Context

The TLV3502AIDG4 implements a push-pull CMOS output stage enabling direct interfacing with TTL and CMOS logic without external pull-ups. Its beyond-the-rails input common-mode range (V− − 0.2 V to V+ − 0.2 V) supports low-voltage signal monitoring across full supply rails.

Unlike the single-channel TLV3501, the TLV3502AIDG4 omits shutdown functionality and integrates two independent comparators in an 8-pin SOIC package. Propagation delay skew between channels is specified at ≤0.5 ns, supporting matched timing in differential or windowed detection architectures.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating frequency supported by the TLV3502AIDG4?

The TLV3502AIDG4 achieves a maximum toggle frequency of 80 MHz at 50 mV overdrive and 5 V supply. This is derived from its 4.5 ns typical propagation delay and 0.5 ns channel-to-channel skew, enabling reliable operation in high-speed clock/data recovery and ATE timing paths where deterministic edge detection is required. The TLV3502AIDG4 does not specify a hard upper frequency limit but maintains stable switching up to 80 MHz under defined load and overdrive conditions.

Does the TLV3502AIDG4 include a shutdown feature?

No, the TLV3502AIDG4 does not include a shutdown pin or function. Unlike the TLV3501, which features a dedicated SHDN pin, the TLV3502AIDG4 is a dual-channel comparator without power-gating capability. Its quiescent current remains at 3.2 mA typical across the full 2.7 V–5.5 V supply range. For low-power applications requiring idle mode, the TLV3501 or other shutdown-capable comparators must be selected instead.

What is the input common-mode voltage range of the TLV3502AIDG4?

The TLV3502AIDG4 supports an input common-mode voltage range from V− − 0.2 V to V+ − 0.2 V. This beyond-the-rails capability allows it to accept input signals slightly outside the supply rails-for example, −0.2 V to 5.3 V when powered from 0 V and 5.5 V. This eliminates the need for external clamping or level-shifting circuitry when interfacing with sensors or legacy analog sources that may exceed nominal rail limits.

Can the TLV3502AIDG4 drive TTL and CMOS logic directly?

Yes, the TLV3502AIDG4 can drive both TTL and CMOS logic directly due to its rail-to-rail push-pull CMOS output stage. At ±1 mA load, its output swings within 30–50 mV of V+ and V−, satisfying TTL high-level input minimum (2.0 V) and CMOS VIH/VIL thresholds across 2.7 V–5.5 V supplies. No external pull-up resistors are needed, reducing component count and board space in digital interface designs.

What package type is used for the TLV3502AIDG4?

The TLV3502AIDG4 uses an 8-pin SOIC (D) package with body dimensions of 3.91 mm × 4.90 mm and standard JEDEC MS-012AC footprint. It is not pin-compatible with the SOT-23 variant (TLV3502CDR), as the SOIC version places V− on pin 5 and V+ on pin 8, whereas the SOT-23 assigns V− to pin 5 and V+ to pin 8 but differs in thermal pad presence and solder mask layout. Board redesign is required when substituting between packages.
