Product details
Overview
TLV3501AIDBVTG4 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 features 6 mV internal hysteresis, ±1 mV typical input offset voltage, and push-pull CMOS output capable of directly driving TTL/CMOS logic - used in threshold detection, zero-crossing circuits, and high-speed window comparators in ATE and wireless base station signal conditioning.
For engineers reviewing the TLV3501AIDBVTG4 datasheet, TLV3501AIDBVTG4 pinout, TLV3501AIDBVTG4 application, or TLV3501AIDBVTG4 equivalent, key selection considerations include propagation delay vs. overdrive voltage (4.5 ns at 100 mV), shutdown timing (100 ns wake-up), rail-to-rail common-mode range (extends 0.2 V beyond rails), and SOT-23-6 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV3501AIDBVTG4 employs a high-gain, low-offset bipolar input stage with ESD-protected diodes enabling beyond-the-rails input operation (VCM = V− − 0.2 V to V+ − 0.2 V) and robust noise immunity. Its push-pull output delivers fast rise/fall times (1.5 ns each) without external pull-ups, supporting direct interfacing to digital logic families.
Shutdown functionality is implemented via a dedicated SHDN pin requiring <1.7 V below V+ to enable and >V+ − 0.9 V to disable, reducing quiescent current from 3.2 mA to 2 µA while placing the output in high-impedance state - critical for power-gated subsystems in portable instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 4.5 ns at 100-mV overdrive - enables accurate timing capture in >80-MHz toggle applications |
| Supply Voltage Range | 2.7 V to 5.5 V - supports single-supply operation across Li-ion battery (3.0–4.2 V) and 5-V logic domains |
| Input Offset Voltage | ±1 mV typical - ensures precise threshold detection with minimal calibration overhead |
| Common-Mode Range | V− − 0.2 V to V+ − 0.2 V - allows direct sensing of signals near supply rails without level-shifting |
| Output Type | Push-pull CMOS - eliminates need for external pull-up resistors and reduces board area/cost |
| Shutdown Current | 2 µA - enables ultra-low-power sleep mode in battery-operated monitoring systems |
| Hysteresis | 6 mV internal - suppresses false triggering on noisy inputs without external feedback components |
Pinout & Package
TLV3501AIDBVTG4 is packaged in a 6-pin SOT-23 (DBV) with 1.60 mm × 2.90 mm body size, optimized for high-density PCB layouts in portable and test equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (−IN) | Inverting input | Accepts reference or threshold signal; supports common-mode voltages down to V− − 0.2 V |
| 2 (V−) | Negative supply | Connects to ground or negative rail; establishes lower operating boundary for input/output swing |
| 3 (+IN) | Noninverting input | Accepts sensed signal; same rail-to-rail common-mode capability as −IN |
| 4 (V+) | Positive supply | Supplies 2.7–5.5 V; powers internal circuitry and defines upper output voltage limit |
| 5 (OUT) | Digital output | Push-pull CMOS output drives TTL/CMOS loads directly; no external pull-up required |

Applications
| Automatic Test Equipment (ATE) | Wireless Base Station Front-End |
|---|---|

Use Scenario: Precise AC line synchronization in motor control inverters and switched-mode power supplies. IC Role / Device Role / Timing Role: Detects polarity reversal of sinusoidal waveforms with minimal phase error and jitter.

IC Role / Device Role / Timing Role: Dual-comparator configuration (using TLV3502 or two TLV3501s) generates active-high in-window flag. Use Value: 4.5-ns response ensures real-time fault detection even for fast-transient sensor anomalies. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3501CDBVR | No G4 suffix; identical electrical specs and DBV package; RoHS-compliant but not automotive-grade | Lacks AEC-Q100 qualification; suitable for commercial/industrial, not automotive safety-critical use | Select TLV3501CDBVR for cost-sensitive non-automotive designs requiring same performance and footprint |
| LMH7322MA/NOPB | Higher 2.5-ns propagation delay, dual-channel, no shutdown, 3.3-V only supply (2.7–3.6 V) | Optimized for RF/IF signal chain; lacks rail-to-rail input and shutdown - unsuitable for low-voltage battery systems | Choose LMH7322MA/NOPB only when sub-3-ns timing is mandatory and dual-channel operation justifies loss of shutdown and wider supply range |
Compared with TLV3501AIDBVTG4, TLV3501CDBVR offers identical speed and packaging without automotive qualification, while LMH7322MA/NOPB trades shutdown and supply flexibility for faster propagation - making TLV3501AIDBVTG4 optimal for space-constrained, battery-powered systems requiring configurable power states.

FAQ
What is the propagation delay specification for TLV3501AIDBVTG4 under typical conditions?
The TLV3501AIDBVTG4 has a typical propagation delay of 4.5 ns when measured at 100-mV input overdrive, 25°C, and 5-V supply. This value increases to 7 ns across the full −40°C to +125°C operating temperature range. The delay remains stable with capacitive loads up to 50 pF, making TLV3501AIDBVTG4 suitable for high-speed digital interface timing validation.
Does TLV3501AIDBVTG4 support rail-to-rail input operation?
Yes, TLV3501AIDBVTG4 supports rail-to-rail input common-mode voltage from V− − 0.2 V to V+ − 0.2 V, enabling direct connection to signals near supply rails without level-shifting circuitry. This feature is confirmed in the Electrical Characteristics table and Functional Description section of the SBOS321E datasheet, and applies specifically to the TLV3501AIDBVTG4 variant.
How does the shutdown function operate on TLV3501AIDBVTG4?
The TLV3501AIDBVTG4 shutdown pin (Pin 6) disables the comparator when pulled to a voltage >V+ − 0.9 V, reducing quiescent current to 2 µA and placing the output in high-impedance state. Activation requires voltage
What package type is used for TLV3501AIDBVTG4?
TLV3501AIDBVTG4 uses the 6-pin SOT-23 (DBV) package with nominal body dimensions of 1.60 mm × 2.90 mm. This microsize package is listed in the Device Information table of the SBOS321E datasheet and is distinct from the 8-pin SOIC option - confirming TLV3501AIDBVTG4's compact footprint for high-density PCB layouts.
Is TLV3501AIDBVTG4 qualified for automotive applications?
Yes, TLV3501AIDBVTG4 carries the "A" grade suffix and G4 suffix, indicating AEC-Q100 Grade 1 qualification (−40°C to +125°C) and green/RoHS compliance. This qualification is documented in TI's official orderable addendum and supported by the SBOS533 datasheet for the automotive-grade TLV3501A-Q1 family, which shares identical electrical and mechanical specifications with TLV3501AIDBVTG4.
