Product details
Overview
TLV3601DBVR from Texas Instruments is a single-channel, 325 MHz high-speed comparator with 2.5 ns propagation delay, rail-to-rail inputs extending 200 mV beyond both supply rails, ±5 mV input offset voltage, and push-pull output. It operates from 2.4 V to 5.5 V and enables narrow-pulse detection (1.25 ns) in LIDAR distance sensing and clock/data recovery circuits.
For engineers reviewing the TLV3601DBVR datasheet, TLV3601DBVR pinout, TLV3601DBVR application, or TLV3601DBVR equivalent, key selection criteria include propagation delay stability over temperature (4.5 ns max at –40°C to +125°C), overdrive dispersion (600 ps), input common-mode range, push-pull drive capability (±30 mA short-circuit current), and SC70-5 package compatibility for space-constrained PCB layouts.
Technical Context
The TLV3601DBVR implements a fully differential front-end with rail-to-rail input stage capable of accepting signals from VEE – 0.2 V to VCC + 0.2 V, enabling direct interfacing with low-voltage logic and analog sensors. Its internal architecture delivers consistent 2.5 ns typical propagation delay across 2.5 V, 3.3 V, and 5 V supplies with <80 ps common-mode dispersion.
Unlike latch-capable variants (TLV3603/3E), the TLV3601DBVR operates exclusively in transparent comparison mode-no LE/HYS control pin-making it suitable for real-time threshold detection where output must track input polarity without hysteresis or latching. It exhibits known startup behavior and stable output state at power-on.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3601DCKR | Same electrical specs; SC70-5 package with identical 1.25 mm × 2.00 mm footprint but different lead finish and tape/reel packaging | No functional difference; used interchangeably in new designs where DBV and DCKR are both qualified | Select TLV3601DCKR if preferred distributor stock or alternate assembly line qualification is required |
| LMH7322MA/NOPB | Higher 1.9 ns propagation delay, differential LVDS outputs, wider 2.7–12.6 V supply, no rail-to-rail inputs | Requires external termination and level-shifting; suited for backplane or high-voltage industrial interfaces | Choose LMH7322MA/NOPB only when differential signaling, higher supply voltage, or lower delay is mandatory-and rail-to-rail input is not needed |
Compared with TLV3601DBVR, TLV3601DCKR offers identical performance in a functionally equivalent package variant, while LMH7322MA/NOPB trades rail-to-rail input flexibility and push-pull simplicity for lower delay and differential output-requiring additional interface components and layout changes.

FAQ
What is the maximum operating temperature range for TLV3601DBVR?
The TLV3601DBVR is rated for operation from –40°C to +125°C ambient temperature. This extended industrial temperature range is validated per TI's recommended operating conditions and supports deployment in under-hood automotive LIDAR modules and industrial test equipment without derating.
Does TLV3601DBVR support dual-supply operation?
Yes, TLV3601DBVR supports dual-supply operation with VEE as the negative rail and VCC as the positive rail. The input common-mode range extends 200 mV beyond both rails (VEE – 0.2 V to VCC + 0.2 V), enabling true bipolar signal handling-for example, ±2.5 V inputs with ±2.7 V supplies.
Is TLV3601DBVR pin-compatible with TLV3603E?
No, TLV3601DBVR is not pin-compatible with TLV3603E. TLV3601DBVR uses a 5-pin SC70 package (IN+, IN–, OUT, VEE, VCC), while TLV3603E uses a 6-pin SC70 package with an additional LE/HYS pin. Board layout and schematic must be modified to accommodate the extra pin and functional differences.
What is the typical input bias current of TLV3601DBVR?
The typical input bias current of TLV3601DBVR is 1 µA to 5 µA over –40°C to +125°C, as specified in the Electrical Characteristics table. This low bias current minimizes loading on high-impedance sensor nodes such as photodiode transimpedance amplifier outputs.
Can TLV3601DBVR drive a 50 Ω transmission line directly?
Yes, TLV3601DBVR can drive a 50 Ω transmission line directly via its push-pull output stage, which delivers ±30 mA short-circuit current. At 3.3 V supply, the output low voltage remains ≤80 mV at 1 mA sink, ensuring robust logic-low margin into 50 Ω loads terminated to VEE or mid-rail.
