Product details
Overview
TLV3402IDRG4 from Texas Instruments is a dual-channel nanopower open-drain comparator optimized for ultra-low-power sensing and threshold detection in battery-powered systems. It delivers 470 nA per channel supply current, supports 2.5 V to 16 V single-supply operation, features –0.1 V to VCC + 5 V input common-mode range, and operates across –40°C to +125°C industrial temperature range - enabling use in portable medical devices and wireless security sensors.
For engineers reviewing the TLV3402IDRG4 datasheet, TLV3402IDRG4 pinout, TLV3402IDRG4 application, or TLV3402IDRG4 equivalent, key selection criteria include its nanoscale quiescent current, rail-exceeding input range, open-drain CMOS output stage, reverse-battery protection up to 18 V, and compatibility with low-power references like REF3312 in high-impedance sensing nodes.
Technical Context
The TLV3402IDRG4 implements a precision comparator core with input offset voltage of 250 µV (typ), 3 µV/°C drift, and 55–88 dB CMRR depending on common-mode voltage. Its differential input resistance exceeds 300 MΩ, and input bias current remains below 250 pA (max) over temperature - supporting high-impedance sensor interfaces without loading.
Propagation delay is overdrive-dependent: 55 µs (low-to-high) and 30 µs (high-to-low) at 50 mV overdrive with 10 pF load and 1 MΩ pull-up; fall time is fixed at 5 µs. The open-drain output requires external pull-up and sinks up to 50 µA while maintaining VOL ≤ 200 mV - suitable for interfacing with microcontroller GPIOs or logic-level translators.
Key Specifications

| 3 | 1IN+ | Noninverting input for channel 1 - accepts signals up to VCC + 5 V without damage |
| 4 | GND | Analog ground reference - must connect to low-noise system ground plane to minimize offset drift |
| 5 | 2IN+ | Noninverting input for channel 2 - independent of channel 1; supports dual-threshold or window detection |
| 6 | 2IN– | Inverting input for channel 2 - electrically isolated from channel 1 inputs; enables separate sensor inputs |
| 7 | 2OUT | Open-drain output for channel 2 - independently controllable; supports OR'ed interrupt signaling |

Applications
| Portable Medical Equipment | Wireless Security Systems |
|---|---|
Use Scenario: Battery-powered ECG patch detecting QRS complex amplitude thresholds to trigger data logging. IC Role / Device Role / Timing Role: Dual comparator monitors differential lead voltage against programmable thresholds; one channel triggers wake-up, the other validates signal integrity.

Use Scenario: PIR motion sensor node using dual thresholds to distinguish human movement from environmental drift. IC Role / Device Role / Timing Role: TLV3402IDRG4 implements window comparator: one channel detects upper threshold (motion onset), second detects lower threshold (return to baseline). Use Value: Open-drain outputs interface directly with ESP32 GPIOs; 55 µs propagation delay ensures sub-100 ms response to intrusion events. |
| Remote Control Systems | Handheld Instruments |
Use Scenario: IR receiver module detecting valid carrier bursts while rejecting ambient light noise. IC Role / Device Role / Timing Role: One comparator compares demodulated signal to adaptive DC reference; second validates pulse width consistency. Use Value: Input bias current <250 pA prevents reference voltage shift in high-Z RC filter networks; 2.5 V minimum supply enables operation from single alkaline cell. |
Use Scenario: Multimeter auto-ranging circuit detecting input voltage crossing decade thresholds (e.g., 200 mV → 2 V). IC Role / Device Role / Timing Role: Dual comparators generate overlapping range-select signals; open-drain outputs drive analog switch control lines. Use Value: 250 µV offset ensures accurate 0.1% full-scale threshold accuracy; –40°C to +125°C rating supports calibration stability across operating environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3402IDR | Same electrical specs and pinout; differs only in tape-and-reel packaging (DR vs DRG4) - no functional difference | Identical use cases; DRG4 is TI's green-lead-free, RoHS-compliant variant with matte-tin finish | Select TLV3402IDRG4 for compliance-critical industrial or medical production; TLV3402IDR for cost-sensitive prototyping |
| TLV3702CDR | Higher supply current (650 nA), faster propagation (25 µs tPLH), push-pull output - no external pull-up needed | Better suited for high-speed digital interfacing; unsuitable where wired-OR or level translation is required | Choose TLV3702CDR when speed > power savings, or when driving CMOS loads directly without pull-up resistors |
Compared with TLV3402IDRG4, TLV3402IDR offers identical performance in non-RoHS assemblies, while TLV3702CDR trades nanopower efficiency for speed and output drive convenience - making TLV3402IDRG4 optimal for battery longevity and flexible interface design.

FAQ
What is the maximum supply voltage for TLV3402IDRG4?
The absolute maximum supply voltage for TLV3402IDRG4 is 17 V, but the recommended operating range is 2.5 V to 16 V. Operation above 16 V risks reliability degradation, and the device is fully specified only within the 2.5–16 V range across –40°C to +125°C. Exceeding 16 V voids parametric guarantees even if below 17 V absolute limit.
Does TLV3402IDRG4 support rail-to-rail input operation?
TLV3402IDRG4 does not support true rail-to-rail input - instead, it offers extended common-mode range from –0.1 V to VCC + 5 V. This means inputs can go 5 V above VCC safely, but cannot swing to the negative rail unless a negative supply is used. For single-supply use, the lower limit is –0.1 V relative to GND.
Can TLV3402IDRG4 drive an LED directly?
No, TLV3402IDRG4 cannot drive an LED directly. Its open-drain output is rated for 50 µA sink current with VOL ≤ 200 mV - insufficient for typical LED forward currents (2–20 mA). An external transistor or dedicated LED driver must be used; the TLV3402IDRG4 output should serve only as a logic-level control signal.
What is the purpose of the NC pins on TLV3402IDRG4?
TLV3402IDRG4 has no NC (no-connect) pins in the SOIC (D) package - all 8 pins are functional. Pin 1 is 1OUT, Pin 2 is 1IN–, Pin 3 is 1IN+, Pin 4 is GND, Pin 5 is 2IN+, Pin 6 is 2IN–, Pin 7 is 2OUT, and Pin 8 is VCC. Confusion may arise from TLV3401 SOT-23 variants, but TLV3402IDRG4 uses every pin.
How does reverse battery protection work in TLV3402IDRG4?
TLV3402IDRG4 incorporates internal protection diodes and current-limiting circuitry that prevent destructive current flow when VCC is reversed (e.g., –18 V applied to pin 8). It withstands up to –18 V on VCC while sinking less than 10 mA - protecting downstream circuitry without external components. This is validated per TI's production test flow, not a theoretical rating.
