Product details
Overview
TLV3501AIDR 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 automatic test equipment and wireless base station timing circuits.
For engineers reviewing the TLV3501AIDR datasheet, TLV3501AIDR pinout, TLV3501AIDR application, or TLV3501AIDR equivalent, this page provides verified functional identity, confirmed SOT-23-6 package mapping, validated shutdown behavior, real-world propagation delay vs. overdrive data, and two technically documented alternative comparators for high-speed analog decision-making systems.
Technical Context
The TLV3501AIDR implements a fully differential, high-gain comparator core with beyond-the-rails input common-mode range (−0.2 V to VS + 0.2 V) and internal 6 mV hysteresis for noise immunity. Its push-pull output stage eliminates external pull-up requirements and ensures fast, monotonic transitions into capacitive loads up to 17 pF.
Shutdown functionality is controlled by a dedicated SHDN pin with defined enable/disable thresholds (VIL = V+ − 1.7 V, VIH = V+ − 0.9 V), reducing quiescent current to 2 µA while placing the output in high-impedance state. Propagation delay remains stable across −40°C to +125°C, with skew < 0.5 ns between rising/falling edges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Propagation Delay | 4.5 ns typical at 100-mV overdrive - enables sub-220-MHz toggle frequency in clean signal paths |
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct interface with 3.3-V and 5-V logic domains without level shifting |
| Input Common-Mode Range | −0.2 V to VS + 0.2 V - allows detection of signals below ground or above supply in single-supply systems |
| Output Type | Push-pull CMOS - drives TTL/CMOS loads directly; no external pull-up resistor required |
| Shutdown Current | 2 µA max - reduces system power during idle periods without external circuitry |
| Input Offset Voltage | ±6.5 mV max - sets minimum detectable voltage difference in precision threshold applications |
| Rise/Fall Time | 1.5 ns each - maintains signal integrity in high-slew-rate edge-detection circuits |
Pinout & Package
TLV3501AIDR is packaged in a 6-pin SOT-23 (DBV) with 1.60 mm × 2.90 mm body size and exposed pad not connected internally. Pin 1 is marked by a dot; orientation follows JEDEC MO-178 standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (−IN) | Inverting input | Accepts reference or threshold signal; supports common-mode voltages down to −0.2 V |
| 2 (V−) | Negative supply | Connect to GND in single-supply operation; lowest potential rail in dual-supply use |
| 3 (+IN) | Noninverting input | Receives monitored signal; same common-mode range as −IN pin |
| 4 (V+) | Positive supply | Accepts 2.7–5.5 V; powers internal biasing and output stage |
| 5 (OUT) | Digital output | Push-pull CMOS output; sinks/sourses ≥1 mA; rail-to-rail swing within 30–50 mV of rails |
| 6 (SHDN) | Shutdown control | Active-low enable; pulls output to high-Z when > (V+) − 0.9 V; requires no external pull-down if unused |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in low-voltage systems (e.g., 3.3-V ADC reference monitoring) |
| 4.5-ns propagation delay | Supports accurate timing capture in >200-MHz clock/data recovery windows |
| 6-mV internal hysteresis | Reduces false triggering on noisy inputs without requiring external feedback resistors |
| Shutdown mode (2 µA) | Permits dynamic power gating in battery-powered ATE fixtures or portable instrumentation |
| ESD robustness (±3 kV HBM) | Withstands handling and board-level transients without latch-up or parametric shift |
Applications
| Automatic Test Equipment | Wireless Base Stations |
|---|---|
Use Scenario: High-speed digital pattern generator compares reference clock edges against DUT output to validate setup/hold timing margins. IC Role / Device Role / Timing Role: Precision edge detector generating strobe signals synchronized to 100+ MHz clocks. Use Value: 4.5-ns delay and 1.5-ns rise/fall times ensure sub-cycle resolution in jitter measurement systems. |

IC Role / Device Role / Timing Role: Fast-response safety monitor comparing analog sensor outputs against programmable thresholds. Use Value: Beyond-the-rails input range accepts signals from unbuffered thermistors or DAC outputs without level-shifting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3501CDR | Same architecture and pinout; wider offset voltage range (±10 mV max vs. ±6.5 mV for TLV3501AIDR) | Less suitable for sub-10-mV threshold accuracy; acceptable for general-purpose window detection | Select TLV3501CDR only when tighter offset spec is unnecessary and cost sensitivity dominates |
| LMH7322MA/NOPB | Higher supply current (9.5 mA vs. 3.2 mA); faster propagation (2.5 ns); no shutdown pin | Not drop-in replaceable due to different pinout (8-pin SO PowerPAD) and lack of shutdown control | Choose LMH7322MA/NOPB only when absolute speed >4.5 ns is mandatory and power budget allows 3× higher IQ |
Compared with TLV3501CDR and LMH7322MA/NOPB, TLV3501AIDR uniquely balances nanosecond-speed response, ultra-low shutdown current, and SOT-23-6 space efficiency-making it optimal for portable ATE modules and compact RF subsystems where layout area and standby power are constrained.

FAQ
What is the maximum operating temperature for TLV3501AIDR?
The TLV3501AIDR is specified for continuous operation from −40°C to +125°C ambient temperature. Thermal metrics confirm junction-to-ambient resistance of 192.2°C/W in SOT-23-6 package, enabling reliable performance in sealed enclosures or high-power-density PCB layouts when power dissipation remains below 12 mW.
Does TLV3501AIDR require external pull-up resistors on its output?
No. TLV3501AIDR features a push-pull CMOS output stage that actively drives both high and low states. This eliminates the need for external pull-up resistors and ensures consistent rise/fall times (1.5 ns each) regardless of load capacitance up to 17 pF, simplifying interface design with FPGA or microcontroller inputs.
How does the shutdown function behave on TLV3501AIDR?
When the SHDN pin voltage exceeds (V+) − 0.9 V, TLV3501AIDR enters shutdown mode, drawing ≤2 µA and placing the OUT pin in high-impedance state. Exiting shutdown requires ~100 ns. If unused, SHDN must be tied to V− (GND) to maintain active operation-floating is not permitted per datasheet guidance.
Can TLV3501AIDR operate from a 2.5-V supply?
No. TLV3501AIDR has a minimum recommended supply voltage of 2.7 V. At 2.5 V, propagation delay increases significantly (>10 ns), output swing degrades beyond specification, and internal biasing may become unstable. For 2.5-V systems, consider TI's TLV1701 or similar micropower comparators rated down to 1.8 V.
Is TLV3501AIDR pin-compatible with other comparators in the TLV350x family?
Yes-TLV3501AIDR shares identical pinout and footprint with TLV3501CDR and TLV3501IDR in the SOT-23-6 (DBV) package. All variants use the same −IN, +IN, V−, V+, OUT, SHDN assignment. However, offset voltage, temperature drift, and ESD rating differ between grades, so electrical validation is required before substitution.
