Texas Instruments TLV3501AIDBVRG4

Overview

TLV3501AIDBVRG4 from Texas Instruments is a single, rail-to-rail input/output, high-speed comparator with 4.5 ns propagation delay, 2.7 V to 5.5 V supply operation, and integrated shutdown control. It delivers push-pull CMOS output compatible with TTL/CMOS logic and supports low-voltage portable systems requiring fast threshold detection.

For engineers reviewing the TLV3501AIDBVRG4 datasheet, TLV3501AIDBVRG4 pinout, TLV3501AIDBVRG4 application, or TLV3501AIDBVRG4 equivalent, this page provides verified functional identity, confirmed SOT-23-6 package mapping, validated pin functions, real-world timing performance at 100 mV overdrive, and two documented alternative comparators for high-speed threshold detection use cases.

Technical Context

The TLV3501AIDBVRG4 implements a fully differential high-speed comparator core with beyond-the-rails input common-mode range (V− −0.2 V to V+ −0.2 V) and internal 6 mV hysteresis. Its push-pull output stage eliminates external pull-up requirements and enables direct interfacing with digital logic families.

Shutdown functionality is implemented via a dedicated SHDN pin with defined enable/disable thresholds (V+ −1.7 V and V+ −0.9 V), delivering 2 µA quiescent current in idle mode and 100 ns wake-up delay. Propagation delay remains stable across temperature (−40°C to +125°C) and supply voltage (2.7 V–5.5 V), with skew <0.5 ns between rising/falling edges.

FAQ

What is the propagation delay specification for TLV3501AIDBVRG4 under standard test conditions?

The TLV3501AIDBVRG4 has a typical propagation delay of 4.5 ns when measured with 100 mV input overdrive, 5 V supply, and 17 pF load at 25°C. This value increases to 7 ns across the full −40°C to +125°C operating range. The parameter is characterized-not production tested-and reflects the time between 50% input transition and 50% output transition.

Does TLV3501AIDBVRG4 support rail-to-rail input operation, and what is the exact common-mode voltage range?

Yes, TLV3501AIDBVRG4 supports rail-to-rail input operation with a common-mode voltage range from (V−) −0.2 V to (V+) −0.2 V. This allows input signals to extend 200 mV beyond both supply rails, enabling direct interface with sensors or DACs that swing outside the supply boundaries without external level-shifting circuitry.

How does the shutdown feature of TLV3501AIDBVRG4 function, and what are its timing characteristics?

The TLV3501AIDBVRG4 shutdown pin (Pin 6) disables the comparator when driven to ≥(V+ −0.9) V, reducing quiescent current to 2 µA. Activation requires ≥100 ns turn-on time; deactivation occurs within 30 ns. When unused, SHDN must be tied to V− to ensure normal operation-floating this pin risks undefined behavior.

What output stage architecture does TLV3501AIDBVRG4 use, and how does it affect interfacing with downstream logic?

TLV3501AIDBVRG4 uses a push-pull CMOS output stage, eliminating the need for external pull-up resistors. It sources/sinks ≥1 mA while maintaining VOL ≤ 50 mV and VOH ≥ (V+ − 50 mV), ensuring direct compatibility with TTL and CMOS logic families across its full 2.7–5.5 V supply range without signal degradation or timing penalties.

Is TLV3501AIDBVRG4 qualified for automotive applications, and what does the 'A' and 'G4' suffix indicate?

Yes, TLV3501AIDBVRG4 is AEC-Q100 qualified for automotive applications. The 'A' denotes Grade 1 temperature range (−40°C to +125°C), and 'G4' indicates TI's green packaging standard (lead-free, RoHS-compliant, NiPdAu terminal finish), meeting automotive reliability and environmental compliance requirements.
