Texas Instruments TLV3201AIDCKR

Overview

TLV3201AIDCKR from Texas Instruments is a single-channel, 40ns propagation delay, microPOWER comparator with push-pull output, rail-to-rail inputs extending 200mV beyond supply rails, 1mV input offset voltage, and 40µA quiescent current per channel. It operates from 2.7V to 5.5V across –40°C to 125°C and is used in high-speed sampling systems for precise zero-cross detection and PWM monitoring.

For engineers reviewing the TLV3201AIDCKR datasheet, TLV3201AIDCKR pinout, TLV3201AIDCKR application, or TLV3201AIDCKR equivalent, key selection criteria include propagation delay vs. load capacitance, input common-mode range beyond rails, push-pull drive capability (±48mA sink/source at 5V), low-offset stability over temperature, and SC70-5 package compatibility with space-constrained portable designs.

Technical Context

The TLV3201AIDCKR implements a high-speed, low-power comparator core with internal 1.2mV hysteresis for noise immunity and no phase inversion when inputs exceed supply rails. Its input stage uses ESD-protected back-to-back diodes with 1kΩ series resistors, enabling robust operation under transient overvoltage conditions up to ±10mA.

It features rail-to-rail input operation with common-mode range from (V_EE – 0.2V) to (V_CC + 0.2V), and a push-pull output stage capable of sourcing up to 60mA and sinking up to 48mA at V_CC = 5V, ensuring direct interface with CMOS logic and moderate-current loads without external pull-ups.

Key Specifications

Pinout & Package

FAQ

What is the maximum capacitive load TLV3201AIDCKR can drive while maintaining 40ns propagation delay?

TLV3201AIDCKR maintains ≤50ns propagation delay up to 50pF capacitive load at V_CC = 5V and 20mV input overdrive, per Figure 6-24. Beyond 50pF, delay increases nonlinearly; for 100pF loads, typical delay rises to ~60ns. Layout best practices include minimizing trace length and using local 100nF ceramic bypass at V_CC to preserve timing integrity in TLV3201AIDCKR applications.

Does TLV3201AIDCKR support true rail-to-rail input operation including beyond the supply rails?

Yes, TLV3201AIDCKR supports input common-mode voltage from (V_EE – 0.2V) to (V_CC + 0.2V), explicitly enabling signals 200mV beyond either rail. This is confirmed in Section 6.5 and 6.7 of the datasheet and verified in Figure 6-4 and 6-5. The internal ESD diode structure safely clamps inputs within ±10mA, making TLV3201AIDCKR suitable for AC-coupled or mismatched-signal interfaces without external protection.

What is the output drive strength of TLV3201AIDCKR at 2.7V supply?

At V_CC = 2.7V, TLV3201AIDCKR delivers minimum sink current of 13mA and source current of 15mA (Section 6.7), with output swing of 230mV above GND and 210mV below V_CC at 4mA load. These values ensure reliable interfacing with 2.7V logic families and low-voltage microcontrollers. Full drive capability is retained across –40°C to 125°C, as validated in Figure 6-14 for TLV3201AIDCKR.

Can TLV3201AIDCKR replace open-drain comparators like LMV7235 without circuit modification?

No-TLV3201AIDCKR has push-pull output, while LMV7235 uses open-drain. Direct replacement requires removing any external pull-up resistor and verifying load compatibility with active-high/low drive. TLV3201AIDCKR's push-pull output sources current (unlike open-drain), so bus-sharing or wired-OR configurations are incompatible. For new designs, TLV3201AIDCKR simplifies layout; for legacy upgrades, schematic review is mandatory before substituting TLV3201AIDCKR.

Is TLV3201AIDCKR pin-compatible with other SC70-5 comparators such as TLV3011 or TLV3501?

No-TLV3201AIDCKR uses standard SC70-5 pinout (OUT, IN–, IN+, GND, V_CC), but TLV3011 (open-drain, integrated reference) and TLV3501 (4.5ns, no beyond-rail input) have different pin functions and electrical behaviors. While physical package matches, signal routing and peripheral components (e.g., reference, pull-ups) differ. TLV3201AIDCKR is only functionally and pin-compatible with TLV3201DBVR (SOT-23-5) and TLV3202 variants in their respective packages.
