Texas Instruments TLV3501AIDBVT

Overview

TLV3501AIDBVT from Texas Instruments is a single, 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 integrated shutdown control. It delivers push-pull CMOS output compatible with TTL/CMOS logic and supports precision threshold detection in high-frequency signal conditioning circuits.

For engineers reviewing the TLV3501AIDBVT datasheet, TLV3501AIDBVT pinout, TLV3501AIDBVT application, or TLV3501AIDBVT equivalent, this page provides verified electrical specs, SOT-23-6 package mapping, shutdown timing (100 ns turn-on), input hysteresis (6 mV), and real-world use cases including zero-crossing detection and relaxation oscillators.

Technical Context

The TLV3501AIDBVT uses a high-gain, low-offset bipolar-CMOS architecture optimized for sub-5 ns switching. Its beyond-the-rails input common-mode range (−0.2 V to V₊ − 0.2 V) enables direct interfacing with signals exceeding supply rails, while internal 6 mV hysteresis improves noise immunity without external components.

Shutdown functionality is implemented via a dedicated SHDN pin that places the output in high-impedance state and reduces quiescent current to 2 µA. The device maintains stable propagation delay skew (<0.5 ns) across temperature (−40°C to +125°C) and load capacitance (up to 50 pF).

Key Specifications

FAQ

What is the maximum toggle frequency supported by TLV3501AIDBVT?

The TLV3501AIDBVT supports a maximum toggle frequency of 80 MHz under 50-mV overdrive and 5-V supply conditions. This performance stems directly from its 4.5-ns propagation delay and fast 1.5-ns rise/fall times. For reliable operation, ensure input slew rate exceeds 20 V/ns and maintain proper PCB layout with minimized trace inductance and grounded guard rings around sensitive pins. TLV3501AIDBVT achieves this spec without external compensation.

Does TLV3501AIDBVT require external hysteresis for noise immunity?

No-TLV3501AIDBVT integrates 6 mV of internal hysteresis, sufficient for most high-speed applications like zero-crossing detection and window comparators with moderate noise floors. External hysteresis is only needed when input noise exceeds ±3 mV or when precise, user-defined thresholds are required. The internal hysteresis is factory-trimmed and remains stable across temperature. TLV3501AIDBVT's design eliminates the need for feedback resistors in basic threshold-detection setups.

How does the shutdown feature affect output behavior in TLV3501AIDBVT?

When the SHDN pin is driven high (≥ V₊ − 0.9 V), TLV3501AIDBVT enters shutdown mode: the output goes to high-impedance state, quiescent current drops to 2 µA, and internal biasing is disabled. Exiting shutdown requires ≤100 ns, after which full-speed operation resumes. During shutdown, the input stage remains inactive-no signal path exists from IN to OUT. TLV3501AIDBVT's shutdown is not a tri-state enable but a complete functional disable.

Can TLV3501AIDBVT operate from a 2.2-V supply?

TLV3501AIDBVT is specified for 2.7 V to 5.5 V operation per datasheet Section 6.3. While it may function at 2.2 V, parameters including propagation delay (increasing to ~7 ns), output swing (reduced headroom), and input common-mode range (narrowed) are not guaranteed. TI explicitly defines 2.2 V as the absolute minimum supply for functional operation-not recommended for production designs. TLV3501AIDBVT must be operated within 2.7–5.5 V for compliance with published specs.

What is the input common-mode voltage range for TLV3501AIDBVT?

The input common-mode voltage range for TLV3501AIDBVT is (V−) − 0.2 V to (V+) − 0.2 V, meaning it accepts signals 0.2 V below ground or up to 0.2 V below the positive rail. This "beyond-the-rails" capability allows direct interfacing with op-amps, transducers, or sensors whose outputs exceed supply limits. At 5-V supply, usable input range spans −0.2 V to +4.8 V. TLV3501AIDBVT maintains rail-to-rail output swing regardless of input position within this range.
